No, you're not adding a new class on the fly. You're creating a new
instance of a ClassFactory subclass on the fly. A class is something
that is defined at compile time by a class { .. } definition. You cannot
create new classes at runtime, only instances of them.

I found this class
package modules.renderers
{
import mx.core.ClassFactory;
import org.osflash.thunderbolt.Logger;
public class InitFactory extends ClassFactory
{
private var initObject:Object;
public function InitFactory(generator:Class, initObject:Object)
{
super(generator);
this.initObject = initObject;
}
public override function newInstance():*
{
var result:* = super.newInstance();
for(var propertyName:String in initObject)
{
try
{
result[propertyName] = initObject[propertyName];
}catch (e:Error)
{
trace(e.message);
}
}
return result;
}
}
}
and i'm able to add a new class on the fly doing
dgc.itemRenderer = new InitFactory(TextInput, {text:'Value inside the
text input'});
now i'm struggling to make the textinput, to get values from the
"data" variable coming from the dataProvider. You know, when inside
the itemrender you can use {data.firstname + ' ' + data.lastname}
like: <mx:TextInput text="{data.firstname + ' ' + data.lastname}" />
With the example i gave above, how i would do that?
Raf
Any idea how i would pass this data to the checkbox label
