Question

I’m trying to create a button that will simply link back to the context root. I noticed flex has a @ContextRoot attribute that appears to work only in certain cases. For example, if I try to use it in the following mxml:

<mx:Button label="Back to Root" click="navigateToURL(new URLRequest(@ContextRoot()), '_parent')"/>

I get the following error: Error: Attributes are not callable.

I can’t seem to find this technique explained anywhere, is there another way?

Thanks for the help!

Thanks to http://devgirl.wordpress.com/ for this solution! I think it is better than the Application.application.url solution:

Use the HTTPService control:

<mx:HTTPService id="home" url="@ContextRoot()"/> 

And then in Action Script:

 navigateToURL(new URLRequest(home.url),"_parent");

works like a charm!
