CHAPTER 18: Spring Web Flow and JSF > Implement the Add Contact Flow
Implement the Add Contact Flow
Having the contact list view and show contact view ready, we can proceed to implement the add contact flow. In the following sections, we will discuss the implementation of the views in the add contact flow.
Step 1: Enter Basic Information
The add contact flow will be started when the user clicks the Add Contact button in the list contact view. The first state is step 1, in which the user will enter the basic information of a contact, including the first name, last name, and date of birth.
Take a look on the code snippet in Listing 18-14, which was extracted from the start state in the flow definition in Listing 18-5 (flow.xml).
Listing 18-14. Navigate from List Contact to Step 1 of Add Contact
<view-state id="start" view="list.xhtml">
<on-entry>
<evaluate expression="contactController.newContactListBean()"
result="viewScope.contactListBean"/>
</on-entry>
<transition on="view" to="show">
<set name="requestScope.contactId" value="contactListBean.selectedContact.id"/>
</transition>
<transition on="add" to="add-step-1">
<evaluate expression="contactController.newContactBean()"
result="flowScope.contactBean"/>
</transition>
</view-state>
