Hello!

I use NHibernate 1.02
I´ve been struggling with this in a couple of days now. But it´s surely a simple question to answer..) I got two tables contact and group, a many to many connection. And a table between named groupcontact.
When I add contacts to a group everything works fine, but how can i delete a contact from the contact table and get the groupcontact table updated with this deletion? I´ve tried with cascade = "delete" but this results in deletion of all contacts and all groups that that contact was tied to. I got inverse = "true" on the group side.

Thanks!

I think you must delete the relationship in both ends as shown below

Code:

d.getEmployees().remove( e );
e.getDepartments().remove( d );
session.save( d );
session.save( e );
