Drag and drop simulated inside panels
I have a big problem with two simulated drag and drop object inside two panels.
I have two panels A & B. In each one I have two simulated drag and drop objects A1 in A and B1 in B.
A1 & B1 are two jpeg inside the panels that with a drag event and a move action became drag & drop objects as set here: http://www.justinmind.com/prototyper/...
I would like see that when I'm in the A panel I could move the jpeg A1 then click on it and arrive to the panel B. In this one i want move the B1 jpeg than click on it and come back to the A panel.
What I get is : moving correctly from panel A to B but when I try to come back, after moving B1, in A there are problems.
B1 does not disappear but remains in the A panels. How is this possible?
How can I fix it?
Thank you very much
