Named Bus in jaxws endpoint not working

[Richard.W.Hansen]

I'm trying to associate an endpoint with a named cxf Bus but getting the 'Can't 
find the request for Observer' error. The service works fine if no bus name is 
specified in the endpoint.  From the server output it appears the service is 
found and loaded. I'm currently using cxf 2.5.1.
