Hi Tim...
No, I didn't mean in the relationship tag. Sorry for the confusion. My
fault entirely. I meant in the <entity> tag.
The descriptor I pasted below is an example of one which fails to deploy on
Orion 1.4.0 because of a now fixed Orion bug (I have not yet retested but
Bugzilla says its fixed in 1.4.4). However, if you exampne the part that
defines the entity beans you'll see what I mean. There is a comment you
can't miss.
Let us know if it works and if not we'll look at other things.
Jim
