htmlText <a> style a:link

[Izzy1138]

I have this Text:
<mx:Text x="10" y="435" link="bookmark()">
<mx:htmlText><![CDATA[<a href='event:#'>LINK</a>]]></mx:htmlText>
</mx:Text>

I want to style the anchor tag like docs say it can:
[url]http://livedocs.adobe.com/flex/3/html/help.html?content=textcontrols_04.html[/url]

I put this in style sheet:
a:link {
color: #0000ff;
textRollOverColor: #4e8ace;
fontWeight: normal;
textDecoration: underline;
}

AND THEN I get this warning: CSS selector condition type is not supported:
':link'
AND the style does not work.

What am I doing wrong?????

Thanks.
