Tree control and a dataprovider as a Class problem?

Hi@ll,

i want to use a class as dataprovider for my <mx:Tree> control. First of all i tried the simple Adobe Tree Demo (Creating a Tree control) - it works. After this i put the Node Data into a Class like this:

package
{
import mx.collections.XMLListCollection;

public class ProjectTree extends XMLListCollection
{
 
  public function ProjectTree()
  {
   var list:XMLList;
   list = new XMLList
     (
      <folder label="Mail">
      <folder label="INBOX"/>
      <folder label="Personal Folder">
         <Pfolder label="Business" />
         <Pfolder label="Demo" />
         <Pfolder label="Personal" isBranch="true" />
         <Pfolder label="Saved Mail" />
         </folder>
         <folder label="Sent" />
         <folder label="Trash" />
      </folder>
     );
   this.source = list;
  }
}
}

Tree definition:

<mx:Tree id="tree" showRoot="true" dataProvider="{projectTree}" creationComplete="getTree()"/>

Declaration:

<fx:Declarations>

     <fx:Object       id="projectTree"/>

</fx:Declarations>

Function:

protected function getTree():*

{

    projectTree = new ProjectTree();

}

First: i get no errors or warnings and the browser starts fine and show the tree.

The Problem is, that the Tree goes "crazy" and didn't show the nodes correctly - all nodes texts is shown at root node.

If i open the node, the other nodes show also the full text of the nodes or have no text.

any idea???
