Hi,


I have a bidirectional many to one relation from A to B. In the mapping I use a bag for the B side of the association mapped with lazy="false" and inverse="true". Inside the bag mapping I have a <cache usage="read-write"/> to enable caching of the collection:

Now, when I retrieve the B side of the association from the database (cache miss) everything is ok and B's collection of A's is initialized successfully. When I do it a second time, and get a cache hit, the collection is empty.

Any ideas what this could be? Are there any specific additional rules that come into play when caching is enabled?

Cheers
Erik

do you mean - no collection from cache, or no collection from cache AND db?
If you got cache hit, and latter see db hit getting collection values by "in (...)" query you probably miss cache directive for you domain objects (e.g A and B)
