Runtime URL

I am trying to make a link to a website. The link should have the same label as its URL. Currently, only the label is showing up properly. The URL is literally being set to {url}. Do you know why?


[Bindable]
private var url:String = "";

<mx:LinkButton
	label="{url}"
	x="125" 
	y="0"
	toolTip="the entry page of this website"
	click="navigateToURL(new URLRequest('{url}'), '_blank')"
/>
