Hi All

I have a Folder object. This folder object has children folders like this:



In my service layer I supply security. This means if a user may not view a sub folder the sub folder should be removed from the parent folder subFolder set. Like this:



If I do this, hibernate updates the subFolder in such a way that it is detached from the parent folder. The thing is, I have set cascade="delete". According to hibernate, cascade="delete" should only delete the sub folders when delete() is called on the parent folder. It shouldnt detach the subFolder in anyway when cascade is set to delete.

It's possible I have misunderstood how hibernate works. In that case, can anybody tell me how can I remove elements from a set or list without hibernate applying changes immediately to the database?

Thanks in advance,
Martyn

I have found the solution. I have added readOnly to my transaction manager for that specific method and now everything works perfectly.
