Dear list,
I have 3 tables with Many to Many rel.: user <-> user_groups <-> group
which are flattened on Object layer.
In Edit User form I have a multiple HTML select for updating groups list for the user being edited.
in my action script I first delete all the groups for this user and then I add all the users which I read from HTML multiple select.
As a result in DB I get duplicate records in user_groups resulting in duplicate groups for one userd.
What am I doing wrong? What is the correct way to update Many to Many flattened relationship?
Thank you.
Dmitry.
