Null binding for SOAP action issue with SOAPProxy

Issue

• I am using SOAPProxy to dynamically call web services. The properties for SOAPProxy are “wsdl” and “soapaction”. SOAPProxy parses a WSDL at runtime and tries to map a soapaction to a binding before in order to call the service address. My understanding is that every binding maps to an operation and a soapaction.
• SOAPProxy finds both binding and soapaction while initializing but at the time it is about to make the call it logs that the binding for that soapaction is null. When this happens, it uses the root element of the request as the operation and tries to find a binding for that operation.
