Sporadic error message

Question

I'm creating an application that uses the Google Maps api.
When I run my file I get an error message about 50% of the time.
I'm using a UIComponent to display my map, and the UI tag has a
resize event handler. The error message indicates that the event
handler doesn't exist, but the handler does exist-- moreover, it
works half the time! Am I attempting to use the event handler
before it has been created is there there some other problem that
I'm not aware of?

That looks like it's an error being generated when it is
trying to dispatch
the event, since it is coming from inside dispatchEvent.
What's the code in
the two event handlers referenced in that UIComponent line?
