Error 1009 when run on different server

Question

My app has a master detail layout populated by remote calls
to cfcs.
A cfc returns a query for the master list and that part works
fine. After the master list is populated or when selecting any row
in the master list another cfc is called to return an object to
populate the detail area.
This part also works fine on our testing server but when I
try it on our production server I get an error 1009:
TypeError: Error #1009: Cannot access a property or method of
a null
object reference.
at orders::OrdersList/::showOrder()
at orders::OrdersList/___Operation2_result()
Both servers appear to be identical (Windows 2003, CF version
7.02
latest hotfixes)
I've checked the cfc and it work as expected on both
machines. Both machines have identical files, i.e., cfc's and swf.
Any idea why the application would work on one server but not
on the
other?
Thanks

Hi Tracy,
Both the testing and production servers are separate from my
development environment. I'm not using a security sandbox. Other
cfc's which return queries (not objects) work ok.
This is the data service call:
<mx:method name="getOrder" result="showOrder(event.result
as ORDERS)" fault="FAB.faultHandler(event)" />
The faultHandler doesn't get called.
showOrder starts like this:
private function showOrder(result:ORDERS):void
Alert.show('showing order');
currentOrder = result;
The alert displays after the error message so I assume that
showOrder is not receiving the result.
