Sorry, let's start again - we're actually agreeing, and it seems I did not express my original post adequately. (PD = Process Definition) I have PD 1 and PD 2. PD 1 refers to PD 2 as a sub-process. I deploy PD 2. Then I deploy PD 1. They are both now deployed. Then I create a process instance from PD 1. It fails, saying that PD 2 does not exist. This is wrong(?) Start from scratch. I deploy PD 1. Then I deploy PD 2. They are both now deployed. Then I create a process instance from PD 1. Everything works fine. Of course, all PDs must be deployed at the time the process instance is created. But should it be necessary that I deploy them in the correct sequence?
