May be it has started but not persisted to db yet. I came across this kind of thing earlier.

And how would I ensure that it has been persisted in the db?

That sounds very odd … do you have an example process that we can try with those REST calls? When you get back a 201, it should be persisted.

thank you for your answer. It happens with every process. For example with the process below (just a start and stop event):

Even more strange is that, if I look into the database (table ACT_HI_PROCINST) the process instance seems to be there (ID_ 17629):

<code>
ID_ PROC_INST_ID_ BUSINESS_KEY_ PROC_DEF_ID_ START_TIME_ END_TIME_ DURATION_ START_USER_ID_ START_ACT_ID_ END_ACT_ID_ SUPER_PROCESS_INSTANCE_ID_ DELETE_REASON_ TENANT_ID_ NAME_
17538 17538 NULL SimpleVariableProcess:1:12504 2016-06-21 09:15:08.977 2016-06-21 09:15:14.707 5732 kermit startevent1 endevent1 NULL NULL NULL
17575 17575 NULL procCallPowerShell:1:20004 2016-06-21 09:15:09.060 2016-06-21 09:15:11.973 2915 kermit startevent1 endevent1 17538 NULL NULL
17600 17600 NULL procCallPowerShell:1:20004 2016-06-21 09:15:12.080 2016-06-21 09:15:14.627 2544 kermit startevent1 endevent1 17538 NULL NULL
17629 17629 NULL myProcess:1:25008 2016-06-21 10:12:07.053 2016-06-21 10:12:07.070 17 kermit startevent1 endevent1 NULL NULL NULL
</code>

But If I call the REST API for the this process instance with GET "http://localhost:8080/activiti-rest/service/runtime/process-instances/17629" I get back:
<code>
{
"message": "Not found",
"exception": "Could not find a process instance with id '17629'."
}
</code>

and if I just call the REST API for all process instances with GET "http://localhost:8080/activiti-rest/service/runtime/process-instances/" I get back:
<code>
{
"data": [],
"total": 0,
"start": 0,
"sort": "id",
"order": "asc",
"size": 0
}
</code>

As I have shown above there are several process instance which should be returned, but are not 😞

a start->end process immediately is finished. If you want to be able to query like you do, your process needs to have a wait state (like a user task).

OK, thank you for the clarification
