Hi,

I have two classes: A has a set of Bs, B can have one or none As:

in the A mapping:


in the B mapping:


I want deleting an instance of A to set B's FK (and java pointer) to null. This was working well before I added the cache but since I added caching I get a
"net.sf.hibernate.ObjectNotFoundException: No row with the given identifier exists" or a JDBC error about a foreign key not satisfied.

I suspect that I have to make A implement LifeCycle and actually iterate through each of A's Bs, setting its reference to A to null. But I hope not.

Any suggestions?

ok ok, so this has to do with "Hibernate has no garbage collection" ... sheesh "you have to delete all references to entities you are deleting from the database" , life was easier without the process-level cache
