start process instance by user

seba1 — Mon, 21 May 2012 14:43:05 GMT

Hello,I would like to start a new instance of a process from a java application.Actually I find this: ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess");‍But I would like to see the process status on Activiti Explorer with the admin user (kermit).How I can assign

I have the same question. How do I assign an owner to a started process? Or when I start a process? I have found that the processes I have started via a web application do not show up in My Instances in Activiti Explorer. However, the same process started via Activiti Explorer are displayed in My Instances.

By looking into the database I found that ACT_HI_PROCINST table has a column 'start_user_id_'. This column contains the user ID of the user that started the process using Explorer. However, processes started using runtimeService.startProcessInstanceByKey( processDefinitionKey, variables) do not have any value in 'start_user_id_'. This is why the running process do not display in My Instances.

In my database, I used SQL to change the 'start_user_id_' to the appropriate user ID. Now the processes display in My Instances.

How can accomplish this from code? I have read through a good portion of the API and have not found a solution.

Thanks!!

I think what you means is called 'initiator', who start the process instance.
This is a activiti extention on start node, you can specify a initiator property, that identifies the variable name in which the authenticated user id will be stored when the process is started. Example:
<startEvent id="request" activiti:initiator="initiator" />The authenticated user must be set with the method BEFORE the process instance is started,

try {
  identityService.setAuthenticatedUserId("bono");
  runtimeService.startProcessInstanceByKey("someProcessKey");
} finally {
  identityService.setAuthenticatedUserId(null);
}

Then, you can refer the initiator(you can treat it as process owner) variable in the rest of process definiton:

<userTask id="examine" name="examinePaper" activiti:assignee="${identity.findLeader(initiator)}">
</userTask>

you can find more information about this in the User Guide Chapter 8. BPMN 20 Constructs "start event'.

I think this should make a nice addition to the documentation. Or a faq…

Ooops… Clearly have not been in the docs for a while…

But it shows how lazy new users are. I see this here and in primefaces forum also…

Absolutely… maybe we just have *too much* docs

(btw, I had to look it up too, didn't remember if it was actually in the docs 😉 )

And in java code?

How do i take the task's process's owner (process initiator) ?

START_USER_ID_ from ACT_HI_PROCINST has a value for that process. (I've used the IdentityService solution ).
task.getOwner() gives null. (I think it goes to ACT_HI_TASKINST's OWNER_)
Am I missing something?

Do I have to create a special process instance variable that stores the owner's value?

If you want to have the "process initiator", you should use the "activiti:initiator" xml-extention (see user guide) to capture the initiator in a variable. Later on, when you need this, you should get it from the process, rather than the task:


String intitiatingUser = runtimeService.getVariable("starter", task.getProcessInstanceId());

Task owner is a different concept, introduced for the more "adhoc" style of tasks. This is, by default, not used by the engine itself perse.

Everything's great when we are in root execution but it doesn't work when my main process flow crete (automatically) a sub-process (callactiviti) - START_USER_ID_ still isn't set for this subproces. How can I change this?

Re: start process instance by user

Are you passing the variable that contains your start user to the sub process?

Re: start process instance by user

tomili — Mon, 01 Oct 2012 12:02:58 GMT

Hymm yes, I was trying to pass "initiator" variable which contains logged in user name "admin"
and map it to "starter"/"initiator" variable in subproces - no effect
Thanks for reply…

Then something sounds wrong … could you file a bug with a simple failing process?
