My code was earlier working with soapUi2.5.
but when I started working with soapUI2.5.1, I started getting this error.

com.eviware.soapui.impl.wsdl.mock.DispatchException: Missing operation for soapAction [<http://SEWSI.ServiceContracts/2008/09/ReceiveSubscription]> and body element [{<http://SEWSI.ServiceContracts/2008/09>}ReceiveSubscriptionRequest] with SOAP Version [SOAP 1.1]

I would appreciate if some can explain me what this signifies.
