Scroller doesn't work in 1.2 RELEASE

Reported by Yaroslav | June 5th, 2008 @ 03:19 PM

Sorry if I'm posting it in wrong format and/or to wrong place, but I've just found a bug in Scroller class and fixed it.

Instead of Element.getPosition() function it seems to be appropriate to use getOffsets(). I'm not sure whether it was bug in getPosition or in Scroller. I fixed it in Scroller.scroll():

  scroll: function(){
    var size = this.element.getSize(), scroll = this.element.getScroll(), pos = this.element.getOffsets(), scrollSize = this.element.getScrollSize(), change = {'x': 0, 'y': 0};
    for (var z in{
      if ([z] < (this.options.area + pos[z]) && scroll[z] != 0)
        change[z] = ([z] - this.options.area - pos[z]) * this.options.velocity;
      else if ([z] + this.options.area > (size[z] + pos[z]) && scroll[z] + size[z] != scrollSize[z])
        change[z] = ([z] - size[z] + this.options.area - pos[z]) * this.options.velocity;
    if (change.y || change.x) this.fireEvent('change', [scroll.x + change.x, scroll.y + change.y]);

There are changes in lines #2 and #6. Hope it helps. Regards

    • Title changed from “Scroller doesn't work in 1.2dev (1555)” to “Scroller doesn't work in 1.2 RELEASE”
    • Tag set to 1.2release, blocker, critical, defect, plugins, scroller

    This fix works. I tested it on 8/23/08 Scroller is COMPLETELY BROKEN in the 1.2 release. This really needs to be done in the 1.2.1 bugfix release.

    For me this fix works on IE7 too. I would prefer to include this fix in the next MooTools release. Until now the Scroller behaviour is completely broken and it took me some hours to find out it was actually a bug.
