when i execute the following:


i get exception:

net.sf.hibernate.HibernateException: Flush during cascade is dangerous - this might occur if an object was deleted and then re-saved by cascade (remove deleted object from associations)

I don't understand why.

Could you help me?

I think the exception explains the problem. It seems you are trying to delete an object that is actively in a relationship with another object. Most likely the object in question (the one being deleted) is in a Set that belongs to another object.

So, either change the cascade properties on that set in the corresponding hibernate mapping file, or make sure you remove the object you are deleting from its associations.

By the way, with proper cascading properties, removing an object from the set and then commiting the changes (e.g., session.flush()) will delete the corresponding db record.

Hi
I've the same issues...is there any news here?
Thanks!
