All,
I could really use some help in identifying where even to begin
looking to figure out what's causing this problem.
I have a ADG that is displaying a GroupingCollection.
I have an application control bar that has a "trash" image. A user
can drag a node from the ADG and drop it in the trash to delete the node
and all it's children.
When you initially get into the application and drag the first node
of the tree to the trash, the delete fires correctly and without error.
When you try to drag the (now) first node of the tree into the
trash, I get the following error:
TypeError: Error #1010: A term is undefined and has no properties.

This only errors when manipulating the second time you try to delete
the first node. You can delete any of the other nodes, repeatedly,
without error. I suspect there is some kind of out of index problem
happening but the dump gives me no ideas on where to look.
Anyone?!
Thanks,
Adrian
