I'm getting an error when adding a node on a treeview that states, "OLE IDispatch exception code 0 from Nodes: Invalid key.." Below is the line of code it fails on. It looks ok to me, but obviously it's not.

m.NewNode = THIS.treeview.nodes.ADD(m.ParentNode, 4, STR(TreeCursor.UniqueID), Paths[i])

UPDATE: The value of STR(TreeCursor.UniqueID) is "    1"
