Update manytomany results in duplicate key exception [message #629336]

Hello,

I have a bi-directional many-to-many relationship (User -> Course).
If I add a course to the users courses list and then add the user to the courses users list, I get a duplicate key exception.

If I only add the user to the courses users list, the users courses list is not updated til I manually call refresh for the user?

Is this the right way?
I've read, that I allways should update both sides of the relationship. But how?

thanks
Dirk
