Problem with parameters and subprocesses

fwachs — Tue, 04 Dec 2012 23:39:53 GMT

Hi all, I'm having a bit of a problem while trying to set parameters to a subprocess. Basically they never get there and I'm not sure what else I can do to set them.Here's the process, sorry, it's in spanish. But I can explain a little bit what each of the service tasks ( which are java classes ) do

An embedded subprocess is just part of the process instance, and has access to all its process variables. So there should be no problem accessing those process variables from inside the subprocess. Or do you mean something else with 'parameters'?

Actually I was being a bit silly about my process. I was "coding" a way to iterate over a list and later I realized that there is a multi instance functionality that was there to solve that kind of functionality.

Here's the process working properly:

Okay, so I assume everything is working correct now? 🙂
