Per your original question with the "drop lines", there's a method
called showDropFeedback() you can override. In the Flex Tree
implementation, most of the work is done in a private function,
updateDropData, so check that out for what you want to do.
I'm not too familiar with the dragComplete mechanism, but it looks
like it should get fired by DragProxy in the mouseUpHandler there, so
you can see what's going on/why it's not getting fired. Some of the
Flex Tree code relies on this, so I'm curious what's going on.
In the dragComplete event, "event.dragInitiator" will give you the
tree you're dropping from. "this" is the tree you're dropping on to.
