[flexcoders] ListEvent.ITEM_EDIT_END is being wrongly dispatched twice if the corresponding event handler includes mx:Alert

[Andriy Panas]

Hi all,


  I've subscribed to ListEvent.ITEM_EDIT_END event for my Tree and put
Alert.show("I am error message").

   My Alert window is being shown twice when the I finish to edit the
tree node name in the the editable TextInput field.

   What I've done wrong? I am on Flex 2.0.1 SDK.

The code sample:
----------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
        layout="vertical"
        initialize="onInitialize()">
        <mx:Script>
                <![CDATA[
                        import mx.events.ListEvent;
                        import mx.controls.Alert;
                        private function onInitialize() : void {
                                tree1.addEventListener(ListEvent.ITEM_EDIT_END, 
onItemEditingEnd);                              
                        }
                                                                
                        private function onItemEditingEnd(event : ListEvent) : 
void {                   
                                event.preventDefault();
                                Alert.show("I am error message");
                        }
                        
                ]]>
        </mx:Script>
        <mx:Tree id="tree1"
                labelField="@label"
                editable="true"
                showRoot="false"
                width="160">
        <mx:XMLListCollection id="MailBox">
            <mx:XMLList>
                <folder label="Mail">

                 <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>
            </mx:XMLList>
