coercition implicite lors de l'utilisation de popupmanager en flex

Question

J'ai dû reformater ma question car j'ai réalisé que j'utilisais une méthode de flexion incorrecte. Mais un problème similaire se produit toujours:

 private function passForm():void { 


      PopUpManager.addPopUp(passTitleWindow, this, true); 
      PopUpManager.centerPopUp(passTitleWindow); 


     } 

          <s:Button includeIn="Detail" x="10" y="329" 
            id= "btn1" 
            label="Pass" 
            click="passForm()" 
            visible="{hasScreen}" /> 

Je clique et la fenêtre contextuelle ne s'affiche pas.

Vous ne pouvez pas instancier un élément basé sur id. Faites votre TitreWindow dans une autre classe et instancier cela.

PassTitleWindow.mxml

      public function set data(value:Object):void 
      {

       _data = value; 
       dispatchEvent(new Event("dataChange"));

    <mx:Text text="Please fill out the following criteria and then click continue."
