Spring WebFlow integration issue

[Christopher Cotton (via Magnolia Forums)]

Attempting to integrate Spring WebFlow into Blossom. At present the initial state is detected, the view is displayed. The problem is that the transition is not triggering (tied to eventId of button in view).
Below is code for webflow-config, registration-flow.config, and regBasicInfo.jsp.

Please advise how to get transition to trigger.
As an aside, the same views and registration-flow.xml work in standalone SpringMVC app.


<!—registration-flow.xml, header, opening tag omitted for brevity -->
<view-state id="register" view="regBasicInfo.jsp">
<transition on="submitRegistration" to="register-success" />
</view-state>

<view-state id="register-success" view="regSuccess.jsp">
<transition on="continue" to="exit" />
</view-state>
<end-state id="exit" view="externalRedirect:/welcome" />

webflow-config.xml

Issue resolved. Using WebFlow 2.4 syntax, but was running under 2.3

The difference was in the name attribute of the hidden input element. Under 2.4 syntax, the following is used:
<input type="hidden" name="_flowExecutionKey" value="${flowExecutionKey}" />

Under 2.3, name is "execution":
<input type="hidden" name="execution" value="${flowExecutionKey}" />
