[jboss-user] [JBoss Seam] - Re: Nested conversations and transaction management

Christian,

thank you again.

Your answers helped me to realize that this is not true.

If you call - do all or nothing -  "persistence context" it is ok for me too.

Anyway, following your answers I get to exactly:

anonymous wrote : 
  | - A long-running conversation that is started when the form in 1) is rendered
  | 
  | - A Seam-managed persistence context with @In EntityManager (read the docs) that is bound to that conversation (automatically)
  | 
  | - The conversation should begin with FlushModeType.MANUAL, so that the persistence context does not write to the database until em.flush() is called
  | 
  | - All your screens and popups run inside the same long-running conversation (JSF POSTback propagates the conversation, for opening a new window etc. and propagation during GET use s:link or s:button)
  | 
  | - ....
  | 

It is not working yet (my application is a little more complex of my description), but I think to be able to fix it myself.

Tank you again.

Regards

Fab.
