Thank you. This is a step forward. The thing is i can't hardcode the collections. In the end product i don't have two but seven lists, so i must be able to detect in the acceptDropBlock which is the receiving collection/list.
I'll try to redo a halt in there to see if I can get the target inside the event, and, from the target, be able to get back to the list then :)
