Key: BPEL-295
URL: https://jira.jboss.org/jira/browse/BPEL-295
Project: JBoss jBPM BPEL
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Engine
Affects Versions: jBPM BPEL 1.1 GA
Environment: Windows XP Professional SP 2
jboss-4.2.2.GA
default memory DB
Reporter: Christoph Salvisberg
Assignee: Alejandro Guizar
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">
<correlations>
<correlation set="serviceCallCreation"
initiate="no"/>
</correlations>
<!--
<fromParts>
<fromPart part="selectSystemPart"
toVariable="selectSystemIn" />
</fromParts>
-->
