Hello, my problem is the next, I have an object of type User, wich contains a set of objects of type UserCalendar, to make the relation between User and Calendar. I maintaine the UserCalendar table from both sides, User and Calendar, with no inverse. I have no problem doing this with an Oracle9 DB.
Now I want to prepare units test, so I'm using hsqldb, and having the unsave transient instance problem.

Can anyone help me??
