RE: [flexcoders] Creating a popup Menu input

[Alex Harui]

How about PopUpButton instead.  I don't really want to dig into editable Menus. 
 It wasn't intended behavior

Subject: [flexcoders] Creating a popup Menu input

Hello,

I want to have a quick little popup text input so I am using a Menu component 
set to editable and using an item renderer. I've almost got it working, except 
I get a null property error when hit enter (coming from 
List.itemEditorItemEditBeginHandler).

Here is my menu creation code:

==========================
private function onBranchCategoryClick(): void {
            var menuLoc:Point = new Point();
            var menu:Menu;

            // Calculate position of Menu in Application's coordinates.
            menuLoc.x = idBranchCategoryBtn.x + 10;
            menuLoc.y = idBranchCategoryBtn.y + idBranchCategoryBtn.height + 20;
            menuLoc = this.localToGlobal(menuLoc);

            menu = Menu.createMenu(Application(Application.application), [''], 
false);
            menu.width = 100;
            menu.height = 25;
            menu.editable = true;
            menu.itemRenderer = new 
ClassFactory(pkg.renderers.BranchCategoryMenuRenderer);
            //menu.rendererIsEditor = true;
            menu.addEventListener( "itemClick", handleCategoryBranchSelected );
            menu.show(menuLoc.x, menuLoc.y);
}
==========================

And the item renderer code:
==========================
<?xml version="1.0" encoding="utf-8"?>
<mx:TextInput xmlns:mx="http://www.adobe.com/2006/mxml"; text="{data}"
            implements="mx.controls.menuClasses.IMenuItemRenderer" change="data 
= this.text">
<mx:Script>
<![CDATA[
import mx.controls.Menu;

import pkg.models.products.ProductNode;


public function get menu():Menu {
            return null;
}

public function set menu(data:Menu):void {

}

public function get measuredBranchIconWidth(): Number { return 0; }

public function get measuredIconWidth(): Number { return 0; }

public function get measuredTypeIconWidth(): Number { return 0; }
]]>
</mx:Script>

</mx:TextInput>
==========================

In my itemClick handler, event.item contains the string that was entered and 
the error occur right after the handler call.


Could anyone please tell me what I'm doing wrong?


Thanks!
