[jonl-percsolutions-com]

If local drop only is enabled on an elementSpec, an error is received, ev is not defined. Error is in method Xonomy.insertDropTargets.

	if(elSpec.localDropOnly(harvestElement($element.toArray()[0]))) {
		if(elSpec.canDropTo) { //remove the drop target from elements that are not the dragged element's parent
			var droppers=$wnd.jQuery(".xonomy .elementDropper").toArray();
			for(var i=0; i<droppers.length; i++) {
				var dropper=droppers[i];
				if(dropper.parentNode!=ev.target.parentNode.parentNode.parentNode) { **//ev is not defined here!!!**
					dropper.parentNode.removeChild(dropper);
				}
			}
		}
	}
