you are explaing?

Thanks!

   Pass a reference to the subclass {this} into the base class, and use it
to refer to subclass items.  That sets up dependencies and typing issues you
should be aware of though.  Probably an event mechanism would be better.

Hi,

I'm trying to use code behind technique and have a compiler problem. I 'm
trying to set an icon in a Button control, but the compiler not allow me to
do this. The following are the classes use to show you the problem


The following is the parent class:

ButtonPanelClass.as
===============

package components {

    import mx.containers.HBox;
    import mx.controls.Button;
    import assets.EmbeddedAssets ;

    public class ButtonPanelClass extends HBox {

        public var new_btn:Button;
    }
}

Next is the mxml that extends the parent class:

ButtonPanel.mxml
=============

<?xml version="1.0" encoding="utf-8"?>
<comps:ButtonPanelClass
    xmlns:comps="components.*"
    xmlns:mx="http://www.adobe.com/2006/mxml "
    >

    <mx:Button id="new_btn" label="New" icon="{EmbeddedAssets.new_icono
}"/>

    <mx:Script>
        <![CDATA[
            import assets.EmbeddedAssets;
        ]]>
    </mx:Script>

</comps:ButtonPanelClass>

Now the assets class I'm trying to use with an icon:

EmbeddedAssets.as
===============

package assets {

    public class EmbeddedAssets {

        [Embed(source="/assets/icons/16/new_icon.png")]
        public static const new_icono:Class;
   }
}


Now you have to use the following tag in your mx:Application and set the
namespace of course (xmlns:comps="components.*")


<comps:ButtonPanel/>


This is the result:

Severity and Description    Path    Resource    Location    Creation
Time    Id
No se encontró el tipo o no es una constante en tiempo de compilación:
ButtonPanel. [Generated code (use -keep to save): Path:
components\ButtonPanel- generated.as, Line: 142, Column: 14]
FlexTest    Unknown    1170796854984    14900

I assume this is a bug in the compiler. Anyone nows a workaround to get my
class compile or I should try to implement my component without use the code
behind technique?

Thanks in advance for any insight on this issue.
