Fl.controls.list And FocusEvent.FOCUS_OUT

Question

Hi,
I am currently using a list control in one simple application. When i select a item in the list control, i display functionalities to move the item up or down in the list or to delete it.
The problem is when select another section of the application, i would like to disable the list functionalities. A focus out event would do the job, but the event is never triggered. Here is how i add the listener to the list component:
this.FileList.addEventListener( FocusEvent.FOCUS_OUT , this.FileList_Focus_Out ) ;
and my event handler function look like the following:
private function FileList_Focus_Out( event:FocusEvent ){ trace( "Focus out" ) ; }
What could cause the event not to be triggered or is the focus out event supported by the fl.controls.list ?
Thanx for your time.
Simon.

And more problems...
I've been having similar problems with fl.controls.combobox:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
at fl.containers::BaseScrollPane/drawBackground()
at fl.controls::List/draw()
at
fl.core::UIComponent/drawNow()[fl\core\UIComponent.as:1198]
at fl.controls::List/scrollToIndex()
at fl.controls::SelectableList/scrollToSelected()
at fl.controls::ComboBox/open()
at fl.controls::ComboBox/onToggleListVisibility()
It turns out that if I comment out part of my program that
does this:
public function getButton(buttonNum:int):Button
return mDialog["button" + buttonNum];
The crash goes away...
So importing fl.controls.button and using it in a method is
causing the importing of comboboxes from an external .swf to not
work.
This is super frustrating...
