Signal name from expression with process variable value

Camunda 7 Topics Discussion & Questions

Hi,
I want to model a signal name as expression like this:
Signal_Car-${execution.getVariable(‘car_no’)}
but the processVariable car_no is not resolved.

If I use:
Signal_Car-${execution.processInstanceId}
the processInstanceId is resolved.

Any idea?
Thanks,
valiu

After carrefull reading I found that the key solution is here :

Blockquote
You can use expressions for the name in the signal event definition. The name is then resolved as soon as a process reaches the scope of the signal.

See: Signal Events | docs.camunda.org

So it it possible to model the signal name using process variable value!
