Rollback execption synchronizing read-only entity bean (?)
After switching one of our entity bean types to use the "Instance Per Transaction Policy", we started getting an exception (included below) on another entity bean type. The stack trace seems to imply that a rollback is occuring when trying to synchronize the PartyAliasRO bean with persistent store (MySql). What is interesting is that the PartyAliasRO bean is defined as being read-only (the relevant snippets from our jboss.xml is included below). Since the bean is read-only, I am at a loss as two why there is a need to synchronize its state.
Any information on what might be causing this problem and more importantly how to fix it would be greatly appreciated.
