Adding a child to a VBox component (FLEX)

First of all I wanted to thank in advance to everyon开发者_如何学运维e that reads this post.

I'm having a problem when adding a child to a VBox component. Is it not the same thing?:

List Item:

  <mx:Script>
        <![CDATA[
              public function addChildren():void {
                    var f:FaqItem=new FaqItem();
                    f.id="newUsersAssistance";
                    this.cont.addChild(f);
              }
        ]]>
  </mx:Script>

  <mx:VBox id="cont" width="100%"  borderThickness="0" verticalGap="0"/>

and:

<mx:VBox id="cont" width="100%"  borderThickness="0" verticalGap="0">
            <view:FaqItem id="newUsersAssistance" />
</mx:VBox>

I am injecting two properties (question and answer) to the FaqItem component from an auxiliar file (using BabelFX) that depends on the id of the FaqItem, but it is only working when I choose the second option. If I use the first option, I get a child but with the text in question and answer fields is empty. I need to use the first option.

Is there anything I am doing wrong?

Thanks again for everything Kind Regards

i don't think you will be able use the id property of the dynamically added component to do Injection. I suggest you keep some bindable variables to bind the value to the dynamic FaqItem.
