Hi,

I have a simple Trade class with a composite id defined below.

I create the Trade fine and save it. I have checked and the table is correctly populated.

I have a handle of the trade I created and I evict it and I try to read it again from the DB. I do get an instance (from load as well as a criteria query) yet:
- the composite id object null;
- when doing getIdentifier(object) it does return the correct identifier.

Any obvious issue with what I am doing and why I get this weird result?

Thanks in advance-
Jean
