EntityHome.persist might call joinTransaction, but EntityController.persist (which I use) certainly does not. Anyway, here's the stack trace:

One thing I noticed is that if I remove the @Out annotation on selectedUser, and instead provide a getter for it (referencing it as userBean.selectedUser in the page), the exception doesn't happen.
