[FlexJS] Uncaught TypeError on component creation

[Justin Mclean]

HI,

I’m getting this error:
Uncaught TypeError: this.generateMXMLAttributes is not a function
    at new components.LinkButton (LinkButton.js:42)
    at components.LinkNavigation.set__links (LinkNavigation.js:102)

When creating this component:

<?xml version="1.0"?>
<js:TextButton xmlns:fx="http://ns.adobe.com/mxml/2009"; 
xmlns:js="library://ns.apache.org/flexjs/basic">
    <js:style>
        <js:SimpleCSSStyles backgroundColor="transparent" borderStyle="none" />
    </js:style>
</js:TextButton>

In ActionScript like so:
var text:LinkButton = new LinkButton();

I assume this is a bug/something misisng? I tried a couple of work arounds but 
nothing (nesting in a container for example seem to work)

Thanks,
Justin
