Hello,
I think I've found an other way by looking into the source:
tree.add(TweenMax.to(function(){},0,{onComplete:function(){$('#map-container').addClass('show-one').removeClass('show-two').removeClass('show-tree').removeClass('show-four');}, onReverseComplete:function(){$('#map-container').removeClass('show-one');}, immediateRender:false}));
Now, reversing is possible, but it pauses the animation.
Another information, that is maybe helpfull for helping: I'm also using Tweendeck
Thanks for helping in advance.
