I have a simple application in which I am trying to use JSF 2.0 with CDI and follow a PRG pattern. So on my main form, I have a simple command button that does nothing but start the current conversation:
<h:commandButton id="continueButton" action="#registrationBean.startConversation}" value="Continue..." />
public String startConversation() {
if (conversation.isTransient()) {
conversation.begin();
}
return "confirm";
}
Theoretically that should turn my current transient conversation into a long running one. Then I have it redirect to a confirmation page:
<navigation-rule>
<from-view-id>/register.xhtml</from-view-id>
<navigation-case>
<from-outcome>confirm</from-outcome>
<to-view-id>/registerConfirm.xhtml</to-view-id>
<redirect/>
</navigation-case>
</navigation-rule>
When I do this, I get the following exception:
org.jboss.weld.context.NonexistentConversationException: WELD-000321 No conversation found to restore for id 1
at org.jboss.weld.jsf.WeldPhaseListener.activateConversations(WeldPhaseListener.java:112)
at org.jboss.weld.jsf.WeldPhaseListener.beforePhase(WeldPhaseListener.java:88)
at com.sun.faces.lifecycle.Phase.handleBeforePhase(Phase.java:228)
at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:99)
If I remove the <redirect/> tag from faces-config, then everything works fine, but then I am not following the PRG pattern.
Is this a bug in Weld? For some reason the conversation that I began before the redirect is somehow lost.
