Description

Found in 4.1.0.14607

Steps to reproduce:
1. Compile and run attached .MXML file.
2. Open the Spark DropDownList control.
3. Select "Five" from the DropDownList.

Actual Results:
The Alert displays, the DropDownList stays open, but the selectedItem changes (as you can see in the application control bar).

Expected Results:
The DropDownList should close.

Workaround (if any):
Use callLater() to slightly delay the Alert.show() call:

<fx:Script>
<![CDATA[
import mx.controls.Alert;

import spark.events.IndexChangeEvent;

protected function ddl_changeHandler(evt:IndexChangeEvent):void

{ callLater(showAlert); }

protected function showAlert():void

{ Alert.show("You changed the DropDownList to " + ddl.selectedItem); }

]]
>
</fx:Script>
