Passing only certain values to a called process

Camunda 7 Topics Discussion & Questions

Hello,

I’d like to call a subprocess from my main process and use a call activity for that.

I’d like to pass some variables of “complex java types” (i.e. not just strings or list or map) to the called process. I’d also like that only certain variables (and not all variables from the main process) get passed to the called process.

Would all the above goals be reached by using a mapping delegate (Call Activity | docs.camunda.org)?

My plan is as follows:

  • Create a mapping delegate that would fill the map with only the values to pass to the called process
  • Specify it for the call activity
  • Define NO input/output parameters and NO variables (and hence specify no value for the “local” checkbox).

Are these the correct actions to take?

Thank you for your recommendations!

Hi @fml2,

as far as I can see, that sounds about the right way to go.

Any specific reasons you want to do this in your own mapping delegate and not via configuration?
Are you going to reuse the mapping delegate in several places?
Do you need any special logic in the mapping procedure?

Best,
Tobias
