[flexcoders] Re-parenting Tree nodes using drag & drop

[Yves Riel]

I looked in the archive but didn't find any useful information for this.
So, here it is: I have a Flex Tree component in which I want to
re-parent a node using drag & drop. Basically, I want to be able to take
a node, drag it on top of another node and that the dragged node be
added as a child. The standard Flex Tree will not allow this (unless I
don't know how to set it up) and I didn't find any open source component
on the net. Does any one have or has seen such a tree?
 
Thanks!
