Can anyone help me solve the issue on initialization of an association in an open session in message http://forum.hibernate.org/viewtopic.php?t=959101?

Any help, including ideas on how to approach debugging the problem myself, would be greatly appreciated.

Tim,

There's a lot of traffic on this forum regarding what constitutes a good
hashCode/equals implementations with Hibernate. Run a search and you'll
find a lot of good advice. Basically, I think your problem boils down to
your hashCode/equals methods using persistent identifiers.
You are following the surrogate key idiom, which implies that these values (ids)
have no business meaning, and so you should not use them in your
hashCode/equals methods.

Also, note that the hashCode/equals are used for uniquely identifying
objects within a set/map etc, but in your case you're actually comparing
Courses using the included assignments - can't courses be identified
using some other properties?

Bonny,
Thanks for the pointers. I'm not sure I understand everything I read but believe that I understand enough for correct code.
