    [ https://issues.apache.org/jira/browse/WOOKIE-44?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12925302#action_12925302 ] 

Paul Sharples commented on WOOKIE-44:
-------------------------------------

I've checked in a fix for IE9 beta which resolves the problem, but most IE users still will be on version 8 unfortunately.  

I tried to implement something to warn the user at runtime of the possible problem, in the 'wookie-wrapper.js file'. I did this by using the try/catch block to trap if the definition of the getter/setter failed. 

Widget.preferences.name=value; // is legal syntax so can't trap it at runtime

However, I'm inclined not to do it this way as the warning would appear on each widget whether its using the syntax or not. Also If several widgets are loaded into a container application this could result in several alert boxes opening - not very nice. As it stands the wookie-wrapper.js will remain silent on the issue.   

I've added an entry for this on the FAQ page, if users want more information. 

As far as as doing a compatibilty check the only other thing I can think of is to parse every .js file on import of a widget zip file into the wookie server and try to replace any of the' Widget.preferences.foo=bar' type syntax with the 'Widget.preferences.setItem('foo','bar')' syntax.
