> Key: MYFACES-3509
> URL: https://issues.apache.org/jira/browse/MYFACES-3509
> Project: MyFaces Core
> Issue Type: Bug
> Components: General

> While running one of our test applications in IE8 we got this "Object doesn't
> support this property or method" error occurring.
> After debugging the code the problem was located in
> api/src/main/javascript/META-INF/resources/myfaces/_impl/_util/_Lang.js code.
> It seems that 'arrForEach' is trying to use the browser native 'forEach'
> function but it fails since IE8 (or IE7) does not implement it.
> Here is a constructed call stack that shows when and where the error occurs:
> (startPos) ? arr.slice(startPos).forEach(func, thisObj) : arr.forEach(func,
> thisObj); -- file:
> api/src/main/javascript/META-INF/resources/myfaces/_impl/_util/_Lang.js,
> line: 346
> this._Lang.arrForEach(this._q, closure, this._space); -- file:
> api/src/main/javascript/META-INF/resources/myfaces/_impl/_util/_Queue.js,
> line: 155
> this.each(broadCastFunc); -- file:
> api/src/main/javascript/META-INF/resources/myfaces/_impl/_util/_ListenerQueue.js,
> line: 80
> this._evtListeners.broadcastEvent(eventData); -- file:
> api/src/main/javascript/META-INF/resources/myfaces/_impl/core/Impl.js, line:
> 564
> ....
> I noticed that in
> api/src/main/javascript/META-INF/resources/myfaces/_impl/_util/_LangQuirks.js
> there's a version of 'arrForEach' function that iterates over elements using
> a plain 'for' loop. Unfortunately this version of the method is not loaded
> because of the condition at the top of the file is not fulfilled. I attached
> a patch that we used to get things going. Of course you might have a better
> solution to this issue.
> Here's also the original JIRA case: http://jira.icesoft.org/browse/ICE-7899
