Just remember another solution:
Regarding performance issues probably the fastest way is to don't use any
itemRenderers.
So if it works in your scenario you may go with this:
public class MySuperVO
{
public var path:String;
public var assetPath:String;
// Getter that returns the path depending on custom conditions
public function get currentPath():string {
return assetPath!=""?assetPath:path;
}
}
// Will invoke our getter
<column id="currentPath"/>
