Pete Muir updated JBSEAM-3493:
------------------------------

        Summary: The EntityHome should not preserve the value of its instance property after entering a nested conversation when having the @PerNestedConversation annotation  (was: The EntityHome should not preserve the value of its instance property after entering a nested transaction when having the @PerNestedConversation annotation)
    Description: 
I have a reflective 1-n associations e.g. Person childof Person.

I would like to create a child from the PersonEdit.xhtml created by seam-gen then adapted by hand.

When I put @PerNestedConversation annotation to my PersonHome the behavior seems to be ok. Each conversation has it's own instance of PersonHome. BUT all of those instances is wired to the same instance of Person (the Entity)...

I've tried to trace modifications on the "instance" field of Home but it's never set; it should stay to null and then call createInstance() but this never happen because the Person instance is the same as the parent conversation one.

I've tried to trace modifications on the "instance" field of Home but it's never setted so it should stay to null and then call my createInstance() overrided method....but this never happen because (as I said) Person instance is the same as the parent conversation one....

Did I miss something?

Or is this a limitation of the CRUD framework?

nowhere on the code the field "instance" is setted so I believe this is due to javassist proxying that my eclipse debugger can't see...

If this feature isn't working how would you implement my "Create child" button to create a new Person has a child of the current conversation "personHome.instance" ?... 



Please try to  make your bug reports intelligible by not including speculation, rhetorical questions, questions about workarounds. I edited the summary to give you an idea.
