Questions about out of the box activiti email task.

[ssun]

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.

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


/** The business key for this execution. Only returns a value if the delegate execution
   * is a process instance.
   * 
   * @deprecated use {@link #getProcessBusinessKey()} to get the business key for the process
   *             associated with this execution, regardless whether or not this execution is a
   *             process-instance.
   */
  String getBusinessKey();
 
  /**
   * The business key for the process instance this execution is associated with.
   */
  String getProcessBusinessKey();
