Dan Allen commented on JBSEAM-2956:
-----------------------------------
Aha! I've determined that there are in fact two problems. The first problem still
stands, that the conversationId is not being recovered on a postback that specifies use of
a natural conversation. But that isn't the source of this particular exception.
The problem is that if a natural conversation is specified and the conversation id is null
(or not found), then an attempt is made to resolve the EL value expression used for the
natural conversation. The problem is, if that EL happens to use a component that relies on
a conversation-scoped, such as the EntityManager, it is going to break because the
conversation hasn't been started yet. Thus, the EL should not be resolved until a call
is made to initialize the conversation id.
I have a patch for all of this I am uploading shortly.
