Webflow setupform

Although the example itself uses a small number of beans you may consider organizing a real-world application with many more beans according to similar principles. Before going into the specifics of each individual context, use the diagram below to get a brief overview of all configuration files including location and purpose. The web. The contextConifgLocation parameter for the DispatcherServlet indicates the Spring MVC web context for the sellitem servlet is spread over two xml files: sellitem-servlet-config.

This service layer context defines beans to be referenced from web flow definitions. The next section discusses the content of this context in more detail. The services-config. For example, the service context defines a DAO bean "saleProcessor" and injects it with a data source:. The services context also declares a bean of type InMemoryDatabaseCreator set to autowire by type meaning that its fields will be compared against the types of beans available in the context and will be automatically set when a match is found.

This table is created in an in-memory hsqldb database called sellitem based on the url property of the dataSource bean. It's also worth noting the bean declarations related to declarative transaction management:. For annotated beans the Spring container automatically creates proxies according to the transaction semantics in the annotation metadata.

The Spring MVC web context is split over two files - sellitem-servlet-config. The sellitem-servlet-config. FlowController acts as gateway to Web Flow and a single controller instance can serve the application as most of the actual control logic is encapsulated in web flow definitions. The sellitem-webflow-config.

It drives the execution of flow definitions configured through the flowRegistry. The flowRegistry bean is configured to load definitions from files ending with "-flow.

This matches to sellitem-flow. As shown here the flow executor can also be configured with a flow listener, which is a callback mechanism for flow execution lifecycle events. Looking inside SellItemFlowExecutionListener, it implements the stateEntering method executed for whenever a new state is about to be entered. The logic in this method checks if the current web flow state has an attribute named "role" and if so it ensures the user has that role:.

Based on the above definitions - web. Note: although it is possible to invoke the shipping-flow directly as well, it expects an input attribute and is intended to be invoked as a subflow. Before tracing the sequence of states in sellitem-flow. The sellitem-beans. The SellValidator will be used to validate form input data.

This editor will bind the shipDate form field in shippingDetailsForm. The formAction bean will use the sale variable for form binding and validation see sellitem-beans. The view state uses a render action to invoke the setupForm method of the formAction bean.

The setupForm method prepares a form object based on the "sale" variable declared at the top of the flow definition. The priceAndItemCountForm. Prior to transitioning the formAction's bindAndValidate method is called to perform binding and partial validation using the validatePriceAndItemCount method of the validator object. The next view state enterCategory based on categoryForm. On submit it transitions to the requiresShipping state:.

The requiresShipping state is a decision state making flow routing decisions. It evaluates a boolean expression against the executing flow and it decides where to transition to next. Here the shipping boolean property of the "sale" form backing object is checked to decide whether to go to the enterShippingDetails subflow state or proceed directly to processSale. The enterShippingDetails subflow state is based on shipping-flow. The form backing object "sale" is passed to it as an input attribute using an attribute mapper declaration:.

The shipping-flow subflow is a simple flow with one view state. It collects the shipping details, binds the data and returns to its parent flow. The id of the subflow end state "finish" is returned to the parent subflow state causing a transition to the processSale action state.

The saleProcessor an instance of JdbcSaleProcessor performs a database update using the values of the Sale object and upon successful completion transitions to the end view state:.

Then end state calls FormAction's setupForm method again. This does not re-create the "sale" form object still in flow scope but it does ensure any custom property editors are registered for use in rendering the JSP. A simpler version of the sellitem-flow is available in the sellitem-simple-flow.

This version uses a view state to gather shipping details instead of using a subflow. You can launch the sellitem-simple-flow using the following URI:.

This web flow is equivalent in functionality to the sellitem-flow definition described above. Conversation scope retains attributes stored in it for the life of the flow execution and is shared by all flow sessions.

For example when invoking the shipping details subflow the parent flow does not need to pass the "sale" form backing object because it is now stored in conversation scope and is accessible to both flows:. Also, when the "sale" object needs to be accessed it is done by referencing conversation cope:. Navigation logic and supporting managed beans are supplied by Spring Web Flow, while UI views and overall servlet processing is based on JSF technology.

For further general information on Web Flow definitions and supporting Java classes for the Sellitem example, please refer to the Sellitem example documentation. In addition, the web. These declarations are very similar to the Sellitem example and explained in more detail there. The webflow-config. These definitions will be explained a little bit further on in the context of how they fit into the JSF phases lifecycle. To plug in Web Flow, a few things must be added once to faces-config.

This is demonstrated in the faces-config. The FlowNavigationHandler delegates view navigation handling to the the Web Flow system when a flow is initiated or resumed. The resolver search algorithm looks in flash scope first, then flow scope, then conversation scope. If no variable is found, this resolver delegates to the next resolver in the chain. Examining the definitions in faces-config. Now we can turn to the question of how to configure the web flow system itself in a JSF environment.

Here the flow executor is configured to support execution of a single flow definition - sellitem-flow. The executor bean has been assigned the id "flowExecutor". This id is significant and is required for the JSF artifacts to detect the executor and its services. The intro. This causes the sellitem-flow to be initiated.

Once a flow is initiated each subsequent JSP page can participate in the flow the flow execution key is tracked for you. The JSF version of the sellitem flow definition is simpler because JSF components care for data binding and validation. This is consistent with normal JSF-isms. There is no need to manually track the flow execution key because it is tracked for you in the JSF view root. The combination of delegating flow variable resolution plus automatic flow execution key management means JSF views selected a flow look like standard JSF views to JSF developers.

Also, JSF components help simplify flow definition logic as the flow no longer has to worry about data binding and validation. For more information and understanding on the Sellitem flow definition logic itself please refer to the documentation for the original Sellitem example. The Shippingrate sample demonstrates the use of Spring Web Flow in combination with Ajaxian techniques.

It consists of several wizard-style steps executed with Ajax requests and refreshing a portion of the page. The input is collected from the user in incremental steps. It is stored in a flow-scoped object and is then used to calcualte a shipping rate. The example also demonstrates invocation of a service-layer bean defined in a Spring context to perform calculations and to provide reference data such as countries and package types.

The services. FlowController is a Web Flow controller. It is the main point of integration between Spring MVC and Spring Web Flow routing requests to one or more managed web flow executions. The FlowController is injected with flowExecutor and flowRegistry beans:. The flowExecutor uses a "simple" repository, which manages execution state in the user session. Given the above definitions the following URI can be used to initiate the getRate-flow:. The shippingrate example consists of several wizard-style steps.

After the initial index. The Ajax requests are done with the help of the Prototype framework and a thin JavaScript layer over it providing convenient functions for processing Ajax form and get requests. The required Javascript libraries are included in index. When index. Functions are first-class citizens and a type in JavaScript. This function invokes Prototype's Ajax. Updater with the specified URL and request parameters.

On success the content of the getRateWizard div is replaced with the response returned from the server. The next few pages are form-based JSP's - selectCustomer. Each of them contains the following JavaScript call at the bottom:. On success the results returned form the server replace the content of the form. Although not demonstrated in this example a back button can be implemented in parallel with the Next button used to advance from one screen to the next.

This would be necessary because the browser back button - a common issue in Ajax applications, contrary to user expectation returns to the page prior to the first Ajax request. As a result of the Ajax requests the entire wizard is able to function within a portion of the page without refresing the remaining information on it. Notice, the use of a start action executed immediately before the JSP is displayed:.

It specifies a form object and a validator to use for form data binding and validation:. The form object of type RateCriteria will be used to collect data from the user in several steps. The form object will be stored in FLOW scope and will not be re-created with each request as long as the flow hasn't reached its end state. The actual binding of html form fields to the RateCriteria object is based on Spring's data binding mechanism. When the selectCustomer. This indicates to Web Flow a transition to the "selectSender" view state.

This view state is defined as follows:. The selectSender view state has a render action: the "rateService" bean that was loaded through the services. The purpose of the render action is to load data required to render the JSP. In this case the rateService bean has a method called getCountries that returns a list of countries to be displayed in a drop-down by the JSP.

The "selectSender" view state also defines one transition: on event with id of "submit" a transition to the "selectReceiver" view state occurs. A pre-requisite for the transition to occur is the successful completion of formAction bean's bindAndValidate method. The attribute "validatorMethod" on the bean specifies the name of the method to invoke on the Validator object specifically for the fields of the current screen.

If the bindAndValidate method does not succeed the transition does not take place and the flow remains in the "selectSender" view state where the user can review the errors and modify the selection. The next two states in the flow - selectReceiver and selectPackageDetails use similar mechnisms. The rateSevice bean is used to retrieve countries and package types for use in the JSP.

The "findRate" action state occurs after all user input has been provided. It is defined as follows:. If you look at the picture above, that's what mine looks like. That said, there are a few really important things that need to happen for this to work. To leverage Vue. These attributes will essentially get mapped as values that bind our form elements to data on a Vue component.

If that sentence made no sense, don't worry about it! We'll still make it work. We need to add Custom Attributes to the form elements - as seen in the picture above. On this sign up form, we're going to be asking the user to supply their first name, last name, email, and password. Make sure that those form fields have the following Custom Attributes on them, as detailed in the list below. Once all the form fields are configured, we're going to also add a Custom Attribute to the form's submit button.

This will serve to make the button's click event with a custom method, rather than submit the form. Okay, great work so far. If you're not familiar with Javascript, don't let the next part intimidate you! It's pretty simple and we'll walk through what's happening.

First off, we need to give the form you just created a unique ID. So in the form element's settings, update the ID input to be "sign-up-form". The reason we need this is that we're going to need to tell the Vue component where to mount, which will give it visibility and control over the child elements all the inputs nested within the form. Once that ID is updated, we're going to update the entire page with a script that goes before the body tag.

The script is below and the screenshot shows exactly where the script needs to go. If you want to, read the in-code comments of the script to get a better understanding of what's happening. However, once you save and publish, we'll have a working sign up page! The sign-up page is technically working at this point.

However, we don't have the necessary pages for sign in, forgot password, or the profile page that will only be for authenticated users. So let's go ahead and build the rest of those pages. You'll see the sign-in page above. It's essentially the sign-up page, without the name fields.

So, to move fast just duplicate the page or copy and paste the sign-up page into a new page called "Sign In". Delete the First Name and Last Name inputs from your form.

On this page, we're going to keep the same Custom Attributes on the email and password inputs, so there are no changes needed there.

However, we need to update the Custom Attribute on the form button. For the form element, update the form ID to be "sign-in-form". This will be the unique ID that the component looks for, just like last time. Now, we're going to update the page with a very similar script to the one we used last time. Finally, we have our forgotten password page! As seen above So let's move forward as we did with the last to pages. Copy the form over to a new page called "Forgot Password".

The custom attributes that we're going to need to add to the form elements are below. Additionally, we'll want to update the form ID on this page to "forgot-password-form".

This is the most simple form of all. Submitting it will send a password reset email. You can fill these field with form variables which allow you to dynamically customize the text that populates the notification fields. These include:. Submitted files will be included as clickable URLs. We recommend that you download and save the files for safekeeping. You can do this automatically by using Zapier to send file submissions to a cloud storage provider.

Alternatively, you can download individual files by right-clicking the file URL and choosing save. You can delete individual form submissions by clicking the trashcan icon. If you're working on a project for a client, you should not view the form submissions for that site. You can declare that you're not the "data controller" of this site and hide the form submission data in the project settings.

If your site collects personal data from EU residents, know your responsibilities as a "data controller". If you're the Data Controller, and you've hidden the form submissions by mistake, you can choose to show form submissions again. If you host websites that collect personal data from EU residents — e.

This data protection self-assessment checklist can be helpful. To host forms externally, you'll need to use a 3rd-party tool to collect form submissions on exported sites. Or, you can embed a 3rd-party form. See form integrations. Each site plan has a monthly form submission limit see chart. Enterprise hosting allows up to unlimited form submissions.

On staged sites, forms will not be submitted after the limit is reached. The count will be reset each month, except for Free staging e. You can clear storage by deleting submissions. Email notifications will be sent from a branded email no-reply webflow. To receive email notifications from an unbranded email address no-reply webforms. You won't be able to access the form data if you've hidden form submissions. Exporting form submission data is only available if you haven't hidden form submissions.
