Web service security + addressing


I´m having some trouble consuming a partner web service which utilize the following:
Soap 1.2
WS Addressing 1.0
WSS Soap Message Security 1.0

The Developer (7.1.2) has no problem generating a service from the wsdl file, but the wsd:action and wsa:to elements are excluded from the request resulting in a timeout when we try to consume the service.

From what I´ve understood wm 7.1.2 does not support wsa, but is there a workaround regarding the wsa:action and wsa:to elements? If adding then manually (maybe it´s the best solution?) it seem to work fine.

Kind regards,
