TableView Bindings & Drag-n-Drop

I have a tableview, whose rows are fed by drag-n-drop from another
table, with its delegate routines for such, but no data source outlet;
the columns are individually bound to their array controller.

All's well until I try and delete. I had been toying with the idea of
dragging rows off to delete, sort of like in Xcode of dragging a
debugger breakpoint off the view, but in the meanwhile deletion is via a
button bound to the remove: method in the table's array controller.

There appears to be a lag between the removal and the tableview's
appearance update. Also my console reports indexing errors (i.e., -1
beyond array bounds 0).

I have a label text field bound to a display pattern which show the
table's count (arranged_objects.@count) which is always accurate, but it
often shows that the display is stale - row visually still there, or
scrolling to move up rows isn't done. If I click outside and then back
into the table, the display gets updated properly.

I take it I'm missing something in keeping the controller in sync with
the drag-n-drop actions but as the text field is always accurate and the
columns are all correct I'm not sure what.

Help!

found it! My notification for selection change didn't notice there was
no selected row ([tableView selectedRow]) properly:

row != NSNotFound

should've been

row != (-1)
