Problem when calling BPEL process (WS) from APEX

Question

I am trying to add a web service call to a BPEL process I have created (tried a few others aswell), but every time I try to add the WDSL file I get the following error:
*1 error has occurred*
The WSDL document contains multiple SOAP bindings. Application Express only supports WSDL's with one SOAP binding. Click Create Web Service Reference Manually to continue creating a reference for this service.
It is a simple BPEL process which works fine when called from the BPEL Console, however I have no success when calling it from APEX.
Am I doing something wrong, or is there a bug in BPEL/APEX?
Oracle BPEL Console v10.1.3.1.0
Apex: 3.2
The WDSL looks like this:

Answer 1

Allow me to reply to my own thread, for the benefit of any others who might want to invoke a BPEL WS from APEX facing the same problem:
Apex does not seem to like asynchronous BPEL processes so the trick is to make a synchronous BPEL process call the asynchronous BPEL process.
