Send data between pages in view stack

Question

Hello all. My language is not the best, so try to understand me.

I have a login page (that working), if details is correct, i want to go to welcome page, and display the first name and last of the user.

Is ok to access to the label in the another page, and how can i do that please?

This is my code:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"&gt;

 <mx:Script>
  <![CDATA[

   import mx.rpc.events.ResultEvent;
   import mx.rpc.events.FaultEvent;
   import mx.controls.Alert;

   [Bindable] public var user:User;
   private function resultHandler(event:ResultEvent):void
   {
    // Is corroect to that :
    welLabel.text ="Hello "+ event.result.firstName +" "+ event.result.lastName + ", Welcome to BSRM";
    myApp.selectedChild=welcomePage;

   }

   private function faultHandler(event:FaultEvent):void
   {
    myApp.selectedChild=errorPage;
   }

Answer 1

Just give the label you want to access an ID:

<mx:Label text="User Name" fontWeight="bold"  x="24" y="44" id="lblUName/>

Then you can access it in any other part of your app:

<mx:Label id="welLabel" x="116" y="81" text="{lblUName.text}"/>
