Nothing is built in into activiti to halt/pauze and resume processes. Only way is to model a waitstate in the process and signal when you want to resume…
But now my question is if there is an example of a wait state and a signal in Activiti examples? I didn't find anything that is close to the issue. Can you point me to a specific place or give me an explanation of how to do it? The user guide doesn't explain the wait state clearly.
