[flexcoders] Dynamic skin on spark.component.textinput

[Netaman]

I stripped away most of the code and just have all the pertinent parts.

The UIComponent is used because I don't know what class I will be adding to the 
application, I have hard coded the string for clarity.
What I am trying to do is dynamically create a textinput spark component, 
but running into a problem with the skin class, when I create the UIComponent 
the skin is null and I get an exception when I add it to the HGroup.

So thought that if I added the skinclass before I added the element to the 
HGroup it would work.

Does anyone have any example code to set the skinclass of a textinput 
dynamically?

private function createTextInput():void {
        var objClass:Class = getDefinitionByName( "spark.components.TextInput" 
) as Class;      
        var newObject:UIComponent = UIComponent( new objClass() );      
        
        var xObject:HGroup = new spark.components.HGroup();
        var newLabel:Label = new spark.components.Label();
        newLabel[ "text" ] = "First Name:";
        newObject["skinClass"] = spark.skins.spark.TextInputSkin;
        newObject.percentWidth = 20;
        xObject.addElement(newLabel);
        xObject.addElement(newObject);
        this.addElement( xObject );
}
