[invalid - please close] [DnD] eventMouseMove not called (observing mousemove only on element)

Reported by Nightfly | October 24th, 2009 @ 02:49 PM

Just saw that this was fixed in 1.8.3.

Please close this ticket.

new Draggable('id', { ghosting: true });

Under specific circumstances which I can't quite nail down(z-index issues and the like), the dragged element won't receive the mousemove event. This results in the draggable not calling the updateDrag function, which in turn disables the DnD functionality for this element.

A fix (dragdrop.js):

var Draggables = {
  drags: [],
  observers: [],

  register: function(draggable) {
    if(this.drags.length == 0) {
      this.eventMouseUp   = this.endDrag.bindAsEventListener(this);
      this.eventMouseMove = this.updateDrag.bindAsEventListener(this);
      this.eventKeypress  = this.keyPress.bindAsEventListener(this);

      Event.observe(document, "mouseup", this.eventMouseUp);
      //Event.observe(draggable.element, "mousemove", this.eventMouseMove); // change this to the next line
      Event.observe(document, "mousemove", this.eventMouseMove);
      Event.observe(document, "keypress", this.eventKeypress);
