#16157 assigned defect

dnd: replace evt.stop with evt.preventDefault in Selector.onMouseDown

Reported by: Simon Speich Owned by: dylan
Priority: undecided Milestone: 1.15
Component: DnD Version: 1.8.1
Keywords: Cc:
Blocked By: Blocking:


dnd.Selector.onMouseDown() calls event.stop(e) on line 268/196 (to prevent the browser from selecting text when the user drags?).

But this prevents using the event mousedown higher up in the DOM hierarchy (e.g. event delegation) and should therefore be replaced with event.preventDefault() instead, which does not cancel the bubbling up. Also see fixed ticket #13994.

], function(declare, on, Selector) {

	return declare([Selector], {

		onMouseDown: function(evt) {
			// onMouseDown calls stopPropagation(), which prevents setting context
			// -> add it back with emit()
			this.inherited('onMouseDown', arguments);
			on.emit(, 'mousedown', {
				bubbles: true,
				cancelable: true

and then use map property in dojoConfig:

var dojoConfig = {
	map: {
		'dojo/dnd': {
			'dojo/dnd/Selector': 'yourOwnModule/dnd/Selector'
