Angular drag n drop: Splice not a function on three level

Question

I'm currently implementing a menu editor. I have the problem, that the first level of elements is perfectly draggable, the levels two and three only return errors about splice or eval not being a function. Dragging works, but the inserting fails.

"Error: scope.$eval(...).splice is not a function"

Answer 1

There now exists a solution for adding own behaviour when insertions take place adding more flexibility:

From 1.4.0 you can now return true in dnd-drop to tell the directive that you will take care of the insertion yourself.
