Alert preventing focusOut from actually changing the focus - apache-flex

Question

Here is a functional example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
public function go():void{
Alert.show("The focus will return to txtOne. Look: ");
}
]]>
</mx:Script>
<mx:VBox>
<mx:TextInput id="txtOne" text="1" focusOut="go()"/>
<mx:TextInput id="txtTwo" text="2"/>
</mx:VBox>
</mx:Application>
When you change from txtOne to txtTwo, the Alert is showed and after pressing OK, the focus will return to txtOne. I don't want that to happen. How to solve this?

Answer 1

Alert.show has close callback argument, so you will know, when it is closed and set focus to something else. Update: you should have flag, indicating, that focus out event can be processed:
private var needAlert:Boolean = true;
public function go():void
{
if (needAlert)
{
Alert.show("The focus will return to txtOne. Look: ",
"", 0, null, myCloseHandler);
needAlert = false;
}
}
private function myCloseHandler(event:CloseEvent):void
{
this.setFocus();
needAlert = true;
}

Answer 2

Try this also to ensure the focus goes where the user wanted it too
<mx:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.events.CloseEvent;
import mx.managers.IFocusManagerComponent;
private var ignoreFocusChange:Boolean = false;
private var focusTargetOnReturn: IFocusManagerComponent;
public function go():void
{
if(!ignoreFocusChange){
focusTargetOnReturn = focusManager.getFocus();
Alert.show("The focus will not return to txtOne anymore. Look: ",
"", 0, null, myCloseHandler);
}
}
private function myCloseHandler(event:CloseEvent):void
{
ignoreFocusChange = true;
focusManager.setFocus(focusTargetOnReturn);
ignoreFocusChange = false;
}
]]>
</fx:Script>
<mx:VBox>
<mx:TextInput id="txtOne" text="1" focusOut="go()"/>
<mx:TextInput id="txtTwo" text="2"/>
</mx:VBox>
