[jboss-user] [JBoss Seam] - Re: Singe Page Application and Conversations

[moshe@egis-software.com]

The problem I have is that  the  parent conversation has an object (selectedDocument)  which almost always gets updated by the nested action. If I were to use a 'per-action' state is there any simple way of updating the object in the parent conversation? 

I would prefer to keep using the SMPC as it  makes my code so much cleaner  :)

The only significant amount of stale data would come from old selectedDocument's, is there any way to manually evict them?

on a side note, what is the recommended way for recovering from a transaction roll-back, At the moment I have lots of:

if (!em.contains(entity)) 
  |    entity = em.find(Entity.class, entity.getId)

scattered around, which does not seem to be the most elegant solution. 

I have tried outjecting the id's and then reloading them in @Create and having an ErrorHandler which does:

  |  ejbContext.setRollBackOnly(); 
  | Contexts.removeFromAllContexts("seamComp")

but it doesn't seam to work as expected.  Will the transaction always rollback  before the next render phase?
