core data drag item more than once

Subject: core data drag item more than once

hi list,

my small app has to tableviews on for all items and the other
is a collection for items I drag'n drop from the all items tableview.
But how do I achieve that I can drag the identical article more than
once to the tableview with the selected items?

I use core data and the relationship between the entities is many-many. When I look in the sqlite db the table for the relation has only two field on for the item an one for the selected item. So it is clear than no double entries are allowed. I would need an auto increment entry in the relationship table, but how can I tell core data this ?

Every small hint to bring me on the right track is welcome.

Thanks
