Drag from ListGrid to TreeGrid

[banang]

I am trying to implement drag-and-drop from a ListGrid to a TreeGrid, and I am failing miserably. I've successfully implemented drag and drop from the tree to the list, but when dragging from the list to the tree I get a js exception thrown at me saying that isc.EH.dragTarget.getData isn't a function.

On the treegrid side I have a onFolderDrop handler that takes care of stuff that's being dropped on the tree, and on the listgrid side I have a onRecordDropHandler. However, when dragging from the list to the tree the onFolderDrop method is never entered, it blows up before that.

TreeGrid dnd settings:

grid.setDragDataAction(DragDataAction.MOVE);
grid.setCanAcceptDroppedRecords(true);  
grid.setCanReparentNodes(true);
grid.setCanDragRecordsOut(true);
grid.setCanReorderRecords(true);

ListGrid dnd settings:

grid.setCanAcceptDroppedRecords(true);
grid.setCanDragRecordsOut(true);
grid.setCanReorderFields(true);

JS exception:

I'm running gwt 2.1 with smartgwt 2.2 (the build from last Thursday) in development mode on Windows 7 using Firefox 3.6.6.

Thankful for your help.

Hard to imagine how this condition could arise (certainly those settings are not enough). In case you hit some kind of major one-night regression, it's worth retrying with the latest code. Beyond that, try to isolate the problem to code we can run.
