Since the delegateExpression isn't in our controll, we can't just set "Expression" fields in it. If you want to configure it, you should so so in your spring-context (or where you create the beans).

If the value should be context-dependent, try using an expression, and passing on the data:


activiti:expression="${myHandler.doParametrisedMethodThing('configuredValue', execution)}"

or use variables perhaps, that you set in another listener/script-task…

thanks for the advice.

one thing i had overlooked is that you can start a process with a Map of process variables apparently. This is also a very convenient way to inject business context info.
