Second, do you run Servlet container in the same VM as JBoss? If so, you could begin/commit transaction in the web layer and no need for value objects.

Hi All,
I've found recently that it's becoming increasingly painful to avoid the 'CMR Collection cannot be modified outside of a transaction' when navigating down CMR many relations. Navigating down a 1 to 1 relation works fine. The thing is, all I'm trying to do is easily display information in web pages. I find myself constantly creating little 'value' classes that contain non-cmr collections just to get around the errors. I must be missing something.
Is there a way to flag CMR lookups as read-only so JBoss doesn't get cranky about requiring transactions all the time?
