Hi,
Something small goes wrong if you have a ProcessFlow instance objects that has a source that makes use of a ProcessFlow variable. Attached is an example model for this bug. There is a source that should create NrTokens number of tokens, where NrTokens is a ProcessFlow variable. This variable has value 2, but only one token is created. The create token activity also creates only 1 token. Something important to note is that this NrTokens variable is defined per instance, if you define it globally it all seems to work fine. It even works if you have defined it globally and then switch back to per instance, only not when you create it as per instance.
Thank you for fixing this bug.
