(I'm an XDoclet newbie)
I have a 1-to-1 unidirectional relationship. It is User ---> Department.
All works seemingly well until ejbPostCreate where I'm setting the
Department CMR field. I've posted my problem on the JBoss CMP forum a
couple times but no response. Others with the same problem seem to also
using XDoclet so I thought I'd see if there's any XDoclet users who've had
this problem and managed to have it solved. Any guidance would be greatly
appreciated. Thank you.
