I'am trying to consume a WCF-Webservice with the XI/PI. First I imported the WSDL of this webservice as an external definition - so far so good. But when I try to create a message-mapping, no fields are available and the XI/PI says something like "null-pointer exception". I suppose it's because there are no field definitions in the WSDL (seems, that the fields I'am missing are downloaded in the background when using anything other to test the webservice, eg. SoapUI).
Can someone give me a hint how to comsume WCF-Services with the XI? Maybe it's a problem with the WSDL, but how can I put the fields/parameters into the WSDL?
Thank in advance
