When having a onEvent of Request/Response type and having an inbound Message from which I wan't to read out the transmitted data in the onEvent-Scope, I recieve an NullPointerException. After the standard ( http://docs.oasis-open.org/wsbpel/2.0/OS/wsbpel-v2.0-OS.html#SA00086 ) there supposed to be this variable implicitly declared, but when trying to access afterweards, I get this nasty error. Declaring the variable outside the scope results in a unitialized variable error, so there seems to be a major trouble with this.
The Initialisation on the client side works, as the correlation works without any problems.
This is when working with the variable attribute inside the onEvent tag.

In addition in the WS BPEL 2.0 Spec it is written, that you can get ridd of th variable attribute and work with the fromParts-Construct instead, but when I delete the variable attribute from the onEvent tag, I can't even deploy my process anymore.



Code-Snippet:
<onEvent partnerLink="ClientPartnerLink" operation="selectSystem" portType="nswsdl:openServiceRequest" variable="selectSystemIn" messageType="nswsdl:selectSystemOperationRequest">

                        <correlation set="serviceCallCreation" initiate="no"/>

                    <!--

                    </fromParts>
