Reparent nodes to leaf nodes Bug

[sanas]

I'm trying to reparent nodes to other "leaf nodes" (nodes without childs).

I set up property setCanAcceptDrop(true); setCanDrag(true) on MyTreeNode Class.

And the TreeGrid is set up...

	employeeTreeGrid.setCanEdit(true);
	employeeTreeGrid.setCanReorderRecords(true);
	employeeTreeGrid.setCanAcceptDroppedRecords(true);
	employeeTreeGrid.setCanDragRecordsOut(true);

	employeeTreeGrid.setDragDataAction(DragDataAction.MOVE);
	employeeTreeGrid.setCanReparentNodes(true);

Thus I can not reparent a node to nodes without childs. For this, I must put the property "setIsFolder(true)" on MyTreeNode Class (force to be a folder), but the control paints a cross to "leaf nodes". (see attachment image)

When I do click on the cross, it throw an exception:

11:06:14.441 [ERROR] [smartbug] 11:06:14.443:MUP1:WARN:TreeGridBody:isc_TreeGrid_0_body:startRowAnimation passed empty row range, aborting: 3,3

When I click in other cross (of node expandable), all runs fine.


I test this with SmartGWT v2.2 & 2.4 using firefox 3.6 (and IE8, IE9, Safari and Chrome)

I attach the source code that it's showcase "Drag Reparent" with my changes.

thanks for your work!!

See canDropOnLeaves.

That's not an exception, just a warning.
