CcBpm Sync - Proxy

Question

Hi Guys,
I've been trying to get this working since last week monday but I get the same error everytime I try some other approach.
Its a simple Soap -> ECC (sync) -> Proxy interface. If this works I'll add a 2nd interface to the bpm.. Error I get: "The process does not support the given synchronous interface or does not support synchronous messages"
in my bpm I've got 2 container parameters (outbound req & resp). I've got 3 steps in my process,
receive (async) -> send (sync) -> send (async)     - gave me this error so I tried
receiver S/A bridge open -> send (sync) -> send S/A bridge close       - still gave me this error.
My opperation mapping has my outbound sync SI & my inbound sync SI.
Config: soap sender to proxy receiver.
Receiver Detr from soap -> bpm
Receiver Detr from bpm -> ECC
Receiver Detr from bpm -> soap
Any idea where I the issue could be?
Thanks,
Jan

Q: To which URL can I send my SOAP message?
           A: The URL for your SOAP sender channel is
           http://host:port /XISOAPAdapter/MessageServlet?channel=p:s:c
           where host is the host name, port is the port number, p is the optional party name, s the service name, and c is the channel name, respectively.The URL given above is valid for 3.0/7.0/7.1.
           A new URL syntax is also valid and is recommended to be used. The URL for the SOAP sender channel is
           http://host:port /XISOAPAdapter/MessageServlet?senderParty=FP& senderService=FS& interface=IF&receiverParty=TP&receiverService=TS&interfaceNamespace=IFNamespace
