Call Activity - PropertyNotFoundException

Hello Folks,I'm getting the following exception while trying to execute a process with a "Call Activity": org.activiti.engine.ActivitiException: Unknown property used in expression at org.activiti.engine.impl.el.JuelExpression.getValue(JuelExpression.java:55) at org.activiti.engine.impl.el.UelEx

Hi,

Process variables are not explicitly defined with Activiti.
So you just set process variables when starting a process instance or when executing a service task.

Best regards,

Hi,

Ok, but my interpretation about the error is correct? I mean, is it caused by non defined property (which is not defined by activiti modeler but MUST be defined in the bpmn xml file) ?

Thanks,
Diogo.

Hi,

It's cause by the fact that the sector process variable is not available in the process instance context.
You don't have to define it in the BPMN XML file.
Maybe it's better to start with the Activiti Designer to get started with what's possible with the Activiti Engine and read through the userguide.

Best regards,

I'm sorry but I still did not get it.

What must I do for it to be in the process instance context?
What I understood from the User Guide is that it's possible to map variables from the SuperProcess to the SubProcess, in other words, as long as the superprocess has the "sectorInParent" variable the engine woud take care of creating the "sector" in the subprocess, as states by <inParameters source="sectorInParent" target="sector"/>
