Spring web stream: transition through view states

Question

In the spring web stream, I need to implement a navigation bar that will allow you to "back off" or resume the stream to one of the previous views.

For instance:

• View 1 = login
• View 2 = My Details
• View 3 = My Messages
• View 4 = Close session

In this example, I would like to return to viewing 2 from 4 pages.

It depends on how you are going to do it. If you do this in one thread, you will have something like this:

<view-state id="loginView" view="login.jsp">
    <action-state bean="someBean" method="login" />
    <transition on="success" to="informationView" />
</view-state> 

<view-state id="informationView" view="information.jsp">
    <render-actions>
        <action-state bean="someBean" method="retrieveInformation" />
    </render-actions>
    <transition on="forward" to="messageView" />
    <transition on="back" to="loginView" />
</view-state>

<view-state id="messageView" view="message.jsp">
    <render-actions>
        <action-state bean="someBean" method="retrieveMessage" />
    </render-actions>
    <transition on="forward" to="closeView" />
    <transition on="back" to="informationView" />
</view-state>

<view-state id="closeView" view="logout.jsp">
    <transition on="jumpBack" to="informationView" />
</view-state>

Going "jumpBack" to "closeView" will take you back to view state # 2, which is your information view.

"returnToInformation" .

= "returnToInformation" to = "returnToInformation" .

"returnToInformation" .

= "returnToInformation" = "displayInformationPage", .
