Hi Andrew ,
I noticed the action namespace for wsdl:input is "http://www.w3.org/2005/08/addressing" in the wscoor.wsdl:
<wsdl:input message="wscoor:CreateCoordinationContext"
wsa:Action="http://docs.oasis-open.org/ws-tx/wscoor/2006/06/CreateCoordinationContext"/>
From http://www.w3.org/TR/2006/CR-ws-addr-wsdl-20060529 Example 4-2, should it be wsaw:Action="..." ?
If the wsa:Action is also valid namespace for ws-addressing action, then it is an issue in CXF.
