END event dispatched too early for animation queues #437

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Both goog.fx.AnimationQueue implementations track only the FINISH event for the 
queued animations.  They dispatch both FINISH and END event after receiving a 
FINISH event for the final animation, which is before the END event for the 
animation.  This is particularly problematic when combined with the behavior of 
goog.fx.dom.PredefinedEffect (arguably buggy also), which executes a final 
animation frame in it's onEnd handler:

goog.fx.dom.PredefinedEffect.prototype.onEnd = function() {
  this.updateStyle();
  goog.fx.dom.PredefinedEffect.superClass_.onEnd.call(this);
};

A user of AnimationQueue should be able to rely on the END event meaning that 
no subsequent animation will be performed.

Seems similar to issue 394.  Should investigate fix for both.
