I have an example app extending seam-javaee-booking app (shipped with seam-3beta1)

Here's my flow (page - action):

1. members.xhtml (members listing) - select member (@Begin)


2. program-registration.xhtml - selectProgram


3. program-registration-select-program.xhtml - register


4. program-registration-confirm.xhtml - confirm (@End)

step 1 is fine, selectedMember gets set

But in Step 2, when selectProgram is called from jsf actionMethod, the page doesn't navigate to next page as per faces-config file, instead it stays same with cid=1 on request param.

Replacing Weld's Conversation interface with Seam's @Begin and @End along with ConversationBoundaryInterceptor results in no change. Removing the navigation elements from faces-config and simply returning the page identifiers in action methods gives another error:

java.lang.IllegalStateException: Context is already active
     at org.jboss.weld.context.AbstractConversationContext.activate(AbstractConversationContext.java:301)
     at org.jboss.weld.jsf.WeldPhaseListener.activateConversations(WeldPhaseListener.java:110)

I've spent 3 days trying to figure out but in vain. Seam 3's hotel booking example is BROKEN (conversation doesn't work either) and there's no end to end example anywhere. Any help, appreciated.
