This issue has been posted here at least twice before without replies:
but I'm trying my luck nevertheless since I believe there must be an answer to this.
The problem:
In the same session, do:
Code:
session.delete(somePersistentObject);
session.get(SomePersistentObject.class, somePersistentObjectId);
and you will get an
Code:
ObjectDeletedException: The object with that id was deleted
Which is not what you would expect by the contract of session.get() which says that no exception will be thrown if the object to be retrieved does not exist.
What happens is that the object still exists attached to the session but may not be returned by Hibernate since it is flagged as deleted. This is absolutely correct behaviour. However, instead of just returning null, the above mentioned exception is raised.
All comments why this behaviour may be a good thing, pointers to an explanation of this etc. are greatly appreciated.

Hibernate version: 2.1, 3.0 and 3.1 all show this behaviour
