I've been wracking my brains on this for a while now, and it hasn't
been a smooth ride. Instead of chanting my experiences in this forum,
it all boils down to my pleading for help from any of you.
Can anyone please provide me a code sample or a URL of such
pertaining to drag-n-drop with a Tree which can demonstrate a
successful drag of one node onto another, and having the dragged node
appear as a child of the node where it was dropped?
In a nutshell, I've gotten as far as getting the node references of
the dragged and dropped nodes within my dragDrop event, including the
index of the node that was dropped on. I can even display these two
nodes using "alert", and their internal toString() methods would
correctly display all the node contents (in XML). However, when I use
the addTreeNodeAt() method on a node that's a parent (i.e. a folder),
nothing happens! And when the node is a leaf (i.e., not a parent of
any child nodes), that node somehow "climbs" up one step higher in
the tree hierarchy, and the dragged node does not appear anywhere!
I would be very grateful to anyone who could provide me some help and
guidance on this please. :(
