Subject [jira] [Resolved] (MYFACES-3444) js-error: _mfInternal is null
Date Fri, 13 Jan 2012 11:08:39 GMT


Werner Punz resolved MYFACES-3444.

       Resolution: Fixed
    Fix Version/s: 2.1.6-SNAPSHOT

The issue was a bug IE8 inherited from IE6, if an innerHTML is performed and some script tags
are inside there is a chance that the markup is messed up, the script tags and other tags
are lost in certain combinations. 

While we have fixed the issue for IE6 it went unnoticed that IE8 also is affected by the problem
(IE9 is not). We simply activated the fixup code for ie6 also for IE7 and IE8 which resolves
the problem.

After activating the bug the problem now seems to be gone away.
