> 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">
