So still reading docs... and the facts is in the Drag.Move var offsetParent = this.element.getOffsetParent()
but: Element Method: getOffsetParent Returns the parent of the element that is positioned, if there is one. so could happen that variable in the Drag.Move is null also its properties. Right?
