Hello,

I'm getting the following error on the merge:


15:28:36 ERROR an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)

I have a graph of object that is coming from the client and the server needs to merge with the database. The incoming objects are not yet loaded in the session.

The top level object is already exists in the DB but child is not (new object). I have cascade="all,delete-orphan" specified in the parent object mapping.

When I call session.merge (topLevelObject) will the child saved to the database ? But getting the above error

Any help would be greately appreciated.


Thanks
