Bug with Box ? error =>TypeError: child is null BoxLayout.js:77:9

[tranquiliste]

Hello all,

I have an error with Box which I don't know how to correct and I wonder if
it's a bug
I have reproduced the issue in a simple code as followed
*TextBinding.mxml*
<?xml version="1.0" encoding="utf-8"?>

<j:Application 
        xmlns:fx="http://ns.adobe.com/mxml/2009"; 
        xmlns:ecrans="ecrans.*"
        xmlns:j="library://ns.apache.org/royale/jewel"
        xmlns:js="library://ns.apache.org/royale/basic"
        xmlns:html="library://ns.apache.org/royale/html"
         xmlns:mx="library://ns.apache.org/royale/mx"
        width="100%"
        height="100%">
        <j:initialView>
                <j:View id="EcranBox" width="100%" height="100%">
                        <ecrans:Ecran2 id="Ecran2" />
                </j:View>               
        </j:initialView>
</j:Application>

*Ecran2Class.as* which extends Box
package ecrans
{
        import mx.containers.Box;

        public class Ecran2Class extends Box
        {
        // Constructeur
                public function Ecran2Class() {
        }
    }
}

*Ecran2.mxml* which only displays a label
<?xml version="1.0" encoding="utf-8"?>
<ecrans:Ecran2Class
        xmlns:fx="http://ns.adobe.com/mxml/2009";
        xmlns:ecrans = "ecrans.*"
        xmlns:j="library://ns.apache.org/royale/jewel"
        xmlns:html="library://ns.apache.org/royale/html"
         xmlns:js="library://ns.apache.org/royale/basic"
         xmlns:mx="library://ns.apache.org/royale/mx"
   width="100%"  > 
        <fx:Script>
                
        </fx:Script>
        <j:Label text="Name :" />
</ecrans:Ecran2Class>

In that configuration I get an error in the console: /child is null

Behaviour is the same if I extends Ecran2Class with HBox, VBox but it works
with Panel

*Important note if I change the jewel Label (<j:Label>) in a MX Label
(<mx:Label>), it works*

Thanks 
Nicolas
