Hi Gerald,
Sorry, I have two words on your solution.
Writing the catch block around your exception is not the good
solution, find and fix why exception occurrence, if we don't have the
way then we need to do so !
1) Adding a eventlistner to the container is bad practise (in your
case)
it works because you have the workaround now, what if there is
another element in your container which is having label property like
Text, it won't throw you exception and also it will navigate try to
navigate to page which is on text's label.
2) By Adding the event listener to the container you are able to
listen every click on the container which is not necessary.
and you are navigate to page with out q value -->
http://www.google.com/finance?q=
3) Adding listner to the individual links will make sense as sampath
said !,
I am filing the code here for your further analysis ...

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";>
<mx:Script><![CDATA[
private function linkHandler(event:MouseEvent):void {
var url:URLRequest = new URLRequest("http://
finance.google.com/finance?q=" + event.target.label);
navigateToURL(url);
}
]]></mx:Script>
<mx:Panel id="p1" title="Click on a stock ticker symbol">
<mx:LinkButton label="ADBE" click="linkHandler(event)"
width="100%" textAlign="left"/>
<mx:LinkButton label="GE" click="linkHandler(event)"
width="100%" textAlign="left"/>
<mx:LinkButton label="IBM" click="linkHandler(event)"
width="100%" textAlign="left"/>
<mx:LinkButton label="INTC" click="linkHandler(event)"
width="100%" textAlign="left"/>
</mx:Panel>
</mx:Application>
