Getting : org.activiti.engine.ActivitiException: Unknown property used in expression: ${courseWorkflowRequestDraftedServiceTask}

Hi,

I have created two beans for serviceTasks as under:

   <bean id="checkCourseWorkflowInitiator" class="edu.bc.eagleapps.course.activiti.servicetask.CheckCourseWorkflowInitiator" >
        <property name="serviceLocatorService" ref="serviceLocatorService" />
    </bean>
    
    <bean id="courseWorkflowRequestDraftedServiceTask"            class="edu.bc.eagleapps.course.activiti.servicetask.CourseWorkflowRequestDraftedServiceTask" >
        <property name="serviceLocatorService" ref="serviceLocatorService" />
    </bean>
‍‍‍‍‍‍‍‍‍

And I mention it in my process bpmn file as under: using activiti:delegateExpression

    <serviceTask id="sid-C8ED341D-B0C8-4A01-BA01-D6995834967A" 
           name="Check if initiator belongs to student services" 
           activiti:delegateExpression="${checkCourseWorkflowInitiator}" >
     </serviceTask>
…
    <serviceTask id="sid-24755FD3-22CE-4EDC-B83E-3FFB0D36F375" 
           name="Change the State of the course to Draft and Put the course proposal in the reviewers outbox" 
           activiti:delegateExpression="${courseWorkflowRequestDraftedServiceTask}"  >
     </serviceTask>
‍‍‍‍‍‍‍‍‍‍‍

Now the issue is the first activiti:delegateExpression="${checkCourseWorkflowInitiator}"  works fine but the same configuration done for later activiti:delegateExpression="${courseWorkflowRequestDraftedServiceTask}" fails with error

org.activiti.engine.ActivitiException: Unknown property used in expression: ${courseWorkflowRequestDraftedServiceTask}
   at org.activiti.engine.impl.el.JuelExpression.getValue(JuelExpression.java:53)

Hi Mansi,

Can you create a jUnit test?

Thanks Martin, for your quick reply.

I tried creating a test case as you suggested, but that worked fine !

Now let me explain you my situation:
I have a webapp, which creates processEngine as well as beans for delegate classes when deployed,
And from my test class when I try to start the process, it starts and one delegate is executed successfully,
now the process stops on a user task,
when I complete the user task programatically, then it is unable to find the next delegate bean.

What should I do in this case?

Hi,
Can you confirm courseWorkflowRequestDraftedServiceTask bean is properly loaded on your webapp?
