I have one-to-many bidirectional association (A*<->B).

A and B and "As" collection in B are cached (EHcache read-write)

In my tansaction I call session.delete(A).

Can hibernate automaticaly update cached-collection "As"?

I would increase the logging level of the ehcache log4j appender, and you can see cache hits/misses to diagnose this.

I've checked this problem.
Hibernate doesn't automaticaly remove deleted objects from collections.
In simple cases (deleting only one object) I can do it on my own but I use cascade delete in many places.
Aftere delete when I try tu use collection (cached erlier) and when I attempt to get properties of deleted object I get this exception:

net.sf.hibernate.ObjectNotFoundException

How can I solve this problem?
