>                 URL: https://issues.apache.org/jira/browse/FLEX-27987
>             Project: Apache Flex
>          Issue Type: Bug
>          Components: Spark: Scroller
>    Affects Versions: Adobe Flex SDK 4.5.1 (Release)
>         Environment: Affected OS(s): Windows
> Affected OS(s): Windows 7
> Language Found: English
>            Reporter: Adobe JIRA

> You can test it in the test application I appended.
> Steps to reproduce:
> 1. Create a List with buttons in the ItemRenderer
> 2. Dispatch an event with the click on the button
> 3. In the main application listen for this event and change the state
> 4. Switch to another window and back to the application
>  
>  Actual Results:
>  A null reference error is thrown in the focusInHandler of the Scroller class because the focusManager is null and there is no check if it isn't null.
>  
>  Expected Results:
>  No error should be thrown.
