Changing eventId(s) per view-state with same view

[alex.haeberle]

Is there a way to have different eventId(s) with different view states, but with the same view?

For example:

View

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<form:form modelAttribute="daForm">
  <c:if test="view-state1">
    <input type="submit" id="next" name="_eventId_next" value="NEXT" />
  </c:if>
  <c:if test="view-state2">
    <input type="submit" id="save" name="_eventId_save" value="SAVE" />
    <input type="submit" id="cancel" name="_eventId_cancel" value="CANCEL" />" />
  </c:if>
</form:form>

What goes into view-state1 and view-state2?

Flow.xml

<view-state id="view-state1" view="view" model="someModel">
  <transition on="next" to="view-state2" />
</view-state>

<view-state id="view-state2" view="view" model="someModel">
  <transition on="save" to="save" />
  <transition on="cancel" to="cancel" bind="false" />
</view-state>

<end-state id="save" />
<end-state id="cancel" />

Could somebody please help me with this issue?
Thanks
Alex

You may be able to do something like this:

<c:if test="${flowRequestContext.currentState.id == 'view-state1'}">
...

See the API for the RequestContext interface for the methods available to you.


Alternatively, to add more context and meaning to your test or variable, you can always add a view-scoped attribute to each view-state, each with a different value. I typically use all caps for flags or view-scoped constants like these.

A very basic example (similar to what you're trying now) would be:

<view-state id="view-state1" view="view" model="someModel">
   <set name="LAST_STEP" value="false"/>
...

<view-state id="view-state2" view="view" model="someModel">
   <set name="LAST_STEP" value="true"/>
...

Then either have your conditionals in your JSP on LAST_STEP or not LAST_STEP, or use a choose/when/otherwise construct.
