Hi,
i tried to add some drag and drop to a file tree demo i found. For
now, i have a problem with the dragging.
You can see the result here :
http://leup.free.fr/filetree/
helper is set to 'clone'
Dragging works but the first item dragged. The dragging stops by
itself and the helper/clone doesn't disappear and stay on top of the
item dragged. (in fact, it seems mouseDrag is called 2 times and
mouseStop and clear methods are not called)
After the first attempt to drag, other attempts works perfectly as
expected.
What does i do wrong ?
ps : sorry for my english
