Hi folks. I wanna know if theres any way to collect all finished tasks of a process definition, not only User Tasks, but also script tasks, email tasks, etc.

Hi,

yes, it is.
Use history service with the proper history level.

Thank you Martin. It works.
Code used:
<code>
List<HistoricActivityInstance> instances = historyService.createHistoricActivityInstanceQuery()
    .processInstanceId(processInstanceId)
    .list();
</code>
Now i can display the process state on diagram
