Hints ActivitiException: Unknown property used in expression

jonathan1

Does anyone have any hints on debugging bpmn files whose execution throws

ActivitiException: Unknown property used in expression
at org.activiti.engine.impl.el.JuelExpression.getValue(JuelExpression.java:55)
….

? It'd be super useful to know what the unknown property is. Can I submit a Jira/request to augment the error message?

I'm afraid Activiti just wraps the exception thrown by JUEL, so I don't think there is much we can do to enhance it.

Would it help if the exception states more explicitely in which step the error happened?

The Cause-exception of the ActivitiException states what property actually is involved…

Eg:

at org.activiti.engine.impl.interceptor.CommandContext.performOperation(CommandContext.java:80)
at org.activiti.engine.impl.persistence.entity.ExecutionEntity.performOperationSync(ExecutionEntity.java:546)
Caused by: org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'outputTransition'

Thanks, frederikheremans. I lost the property name in the kilometer-long stack trace.

My initial suggestion was to update the passing of the PropertyNotFoundException in JuelExpression.java, Activiti 5.10, line 55 from

throw new ActivitiException("Unknown property used in expression", pnfe);<br>to

throw new ActivitiException("Unknown property used in expression: " + pnfe.getMessage(), pnfe);<br>
It's a pretty minor change, I should have had the patience to look deeper into the stack trace.
