Why the heck do you need to re-cast as an XMLListCollection? This is a actually really simple...
var squat:XML = XML(squaresGrid.selectedItem); var myValue:String = squ...@myproperty OR squat.myProperty (depending on if it's a node or attribute) It does work. I've done it hundreds of times. Don't know what you're doing wrong... -Julian ________________________________ From: Dan Pride <[email protected]> To: [email protected] Sent: Sat, November 21, 2009 11:43:34 AM Subject: Re: [flexcoders] Syntax Question Thanks for the response. Its an ArrayCollection of XML objects. var squat:XMLList = squaresGrid. selectedItem. NameCol; will trace as an XML List but I can not seem to get the list to then recast as an XMLListCollection so I can get at it.
