Bug: Runtime error IE8

[evannieuwburg]

Reporting a bug here. On IE8 my animation complete kills the experience, throwing a runtime error popup. Works fine though on Chrome and proper browsers.
 
I'm doing the following:
 

animateInBars : function(callOnComplete){TweenMax.staggerFrom( dom_element.find('.barchart-bar'), 0.5,{height:"0%", ease:Elastic.easeOut}, 0.01, callOnComplete);},

 
The animation works fine, but when the onCompleteAll kicks in, it crashes. IE8 throws this at me:
Object expected TweenMax.js, line 308 character 7

That corresponds to this code on line:
onCompleteAll.apply(onCompleteAllScope, onCompleteAllParams);
 
So I tried adding an empty array for the onCompleteAllParams:

animateInBars : function(callOnComplete){TweenMax.staggerFrom( dom_element.find('.barchart-bar'), 0.5,{height:"0%", ease:Elastic.easeOut}, 0.01, callOnComplete, []);},

And that fixes it

You're absolutely right - sorry about that. It'll be fixed in the upcoming 1.9.1 release (due out soon).
