Hi Tihomir,
that makes sense, of course. I don't think we need a separate method for that, it's just that I wanted to know what's the best practice, because I'd like to control variable lifecyle.
For example, Drools has a different logic for that, where I can insert and retract an object from a knowledge session, so I thought can I use this mechanism in a workflow process scenario, for example to trigger some event when a variable is removed from a process instance.
Thanks,
Miljenko
