I am currently trying to route the process flow according on a local variable that i declared within the example.java code where the workflow is being executed (claim and execute tasks and so on). I declared a
boolean requestApproved = true;
within my java class that i want to be checked for at the gateway and route the flow accordingly. But i get the following error message:Exception in thread "main" org.activiti.engine.ActivitiException: Unknown property used in expression: ${requestApproved == "true"}
What's wrong with my code? Any ideas?
