Null object passed into Dispatch marshalling

I've googled this error message, but all the results seem to apply to
bugs in the CXF samples. I'm using the message provider technique for
handling incoming SOAP messages and continually receive this
exception:

Nov 1, 2007 10:59:36 AM org.apache.cxf.phase.PhaseInterceptorChain doIntercept

It never reaches my code, so I assume this is either a bug in CXF or
an incorrect configuration on my part. Any ideas?

Todd,

Are you sure it's not hitting your code?    This exception is on the 
OUTBOUND chain while trying to write a response.    That suggests your 
code was called and you returned "null" from your invoke method.  (which 
according to spec is not allowed)

Do I need to write an interceptor? Or do I need to configure the
endpoint to not attempt to marshal the request?
