when i run a form which is a parent form (contains a desktoppane) for various JInternalForms with JTables populated (binding) with data from a db tbl
I automatically generated the tables by dragging a node from a connection; holding down cntrl key and then releasing on top of an internal frame
when i run the parent form i get the following error
