Re: [JBoss-user] Read only CMR Collections?
What about using filters to begin/commit transactions?

I'll have to look into what value objects can provide me with regard to CMR collections, then. -Neal On November 10, 2003 03:03 pm, Alexey Loubyansky wrote: First, it is the spec requirement.

[JBoss-user] Read only CMR Collections?
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.
