[vata2999]

Hi, i created a simple (add friend) process base on bonus chapter in seam in action book
after i want to start process i've got this exception

Caused by java.lang.IllegalStateException with message: Could not commit transaction

Caused by javax.transaction.HeuristicMixedException with message:

any idea ?

my actioBean method

@End     
@CreateProcess(definition="Courier")
     public void registerCommunityComment() {
          entityManager.persist(communityComment);          
          entityManager.flush();
}

PS : when flushmode is automatic and i don't use any other entity to persist everything goes fine, however it's intersting that evrything commit in databse but exception occured
