Questions about out of the box activiti email task.

Where can I find a complete list of ${variables} that I can use in the email? And I not only want to use it in the email body but a lot of other places such as use ${initiator} of the process, ${assignedTo} on the cc line. Use ${businessKey} of the process on the subject line, etc.

Thank you very much!

Hi Gordon,

Variable list depends on the process instance (you can create variables in runtime). The easiest way to get a variable list is

debug the process instance
write variables into the log
check DB for variables

Thank you Martin. I tried to use ${businessKey} and did not work. I guess it is not in the variable list of the process. I guess I have to copy it to the list, right?

Hi,

businessKey is not a variable that's correct. execution is and you could get to the business key via that perhaps, so execution.businessKey. In addition you can reference variables directly. That's it basically.

Best regards,

I tried ${execution.businessKey} but it does not work. I was using it in a simple email task. And I'm 100% sure the business key is set on the process instance when I start it. It seems that ${execution.businessKey} is something with an empty value. Unlike just ${businessKey} , it does not throw exception.

Hi,

use getProcessBusinessKey() instead
