Hi there
I'm having a little problem with my process. I invoke a ESB service and
depending on the returned value the right transition should be taken.
This works fine as long as I use a seperate action-node and decision-node. But
that means that I need two nodes for every branching.
I've read that this should be possible using one decision-node with a
node-enter event, but this doesn't seem to work for me.
I have the following code:
<decision name="decision2">
| <event type="node-enter">
| <action name="esbAction"
class="org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler">
| <esbCategoryName>RechnungBearbeiten</esbCategoryName>
| <esbServiceName>WurdeRechnungBestellt</esbServiceName>
| <millisToWaitForResponse>5000</millisToWaitForResponse>
| <jbpmToEsbVars>
| <mapping jbpm="lieferantenNr"
esb="rechnung_kontrolle_lieferantenNr"></mapping>
| <mapping jbpm="auftragsNr"
esb="rechnung_kontrolle_auftragsNr"></mapping>
| </jbpmToEsbVars>
| <returnVars>
| <mapping jbpm="istBestellt"
esb="rechnung_kontrolle_istBestellt"></mapping>
| </returnVars>
| </action>
| </event>
| <transition to="skonto" name="to skonto"><condition
expression="#{istBestellt==false}"></condition></transition>
| <transition to="end-state1" name="to end-state1"><condition
expression="#{istBestellt==true}"></condition></transition>
| </decision>
When I run this process, I get the following error at the decision-node:
anonymous wrote : ERROR [GraphElement] action threw exception: transition
condition #{istBestellt==false} evaluated to 'false'
| org.jbpm.JbpmException: transition condition #{istBestellt==false}
evaluated to 'false'
The ESB service returns true, and of course #{istBestellt==false} evaluates to
'false'. This is ok in my eyes, but the execution stops after the JbpmException
and doesn't test the next condition.
What am I doing wrong? I have the feeling that jbpm evaluates the transition
conditions before the return value is really saved as a process variable.
