Editor.as map_mouseUpHandler Error

Question

I've customized the Editor Widget a great deal... and don???t see this error in the SFV.
While debugging in Eclipse using the Flex API 2.3.1... With the debugger off, there is no error.
If I select a polygon and then attempt to select another, I get the following error:
[INDENT]TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.esri.ags.components::Editor/map_mouseUpHandler()  [/INDENT]
If I select the map (which un selects the polygon) between polygons, I do not get the error.
Any thoughts on how to remove the (I am guessing this is how to fix it) the map_mouseUpHandler listener?

I would really like to know where to obtain the Editor.as file! 
I was hoping the 2.4 API would reveal more of the code behind regarding the Editor and FeatureLayers??? Oh well.

Suggestions are appreciated.
Thanks

I'm having a similar issue working with the flex API editor component.  I get the problem when I try to remove the editor component.  It appears that the editor adds a mouse  up event listener to the map but doesn't clean up after itself when removed, thus causing a null exception when the event listener tries to reference the editor.

Anyone know if there's a way to remove the listener manually?
