svn commit: r812095 - /myfaces/core/trunk/api/src/main/javascript/META-INF/resources/myfaces/_impl/_util/_Utils.js

New Revision: 812095

URL: http://svn.apache.org/viewvc?rev=812095&view=rev
Log:
https://issues.apache.org/jira/browse/MYFACES-2348

Fixed the eval issue, eval should now behave the same for evaluated
scripts over all platforms and browsers, thanks to scoping the eval itself
before actually calling eval.
(This is mostly a fix for browser bugs instead of a fix in our codebase)
