Modify process instance name

mrahn — Wed, 10 May 2017 06:22:57 GMT

Dear community.Is there a way to modify the name of a process instance?I'd prefer to use an execution (or task) listener for this purpose. Having ${processInfoBean.getProcessName(execution)} to get the process instance name I wonder whether there is a method to modify the process instance name.Best

You can user public api 'RuntimeService.setProcessInstanceName(String processInstanceId, String name)'.

RuntimeService (Activiti - Engine 5.22.0 API)

* Java example

execution.getEngineServices().getRuntimeService().setProcessInstanceName(execution.getProcessInstanceId(), %NAME%);

* Expression example

${execution.getEngineServices().getRuntimeService().setProcessInstanceName(execution.getProcessInstanceId() , %NAME%)}

Thank you daisuke-yoshimoto!

Your reply was very helpful!

Since it didn't seem to work for me I imported your process and it didn't work either.

What I found so far is, that modifications of the process intance name doesn't work before end of the first user task. So for the first user task it does not work with the Start event of the Execution Listener or the Create event of the Task Listener. But it does work with the End event of the Execution Listener and the Complete event of the Task Listener. For the second user Task it does work with the Start event of the Execution Listener and the Create event of the Task Listener. Using a Service Task (or Script Task) between Start and the first user task doesn't help as well. The process name cannot be modified before the end of the first user task.

We run Alfresco Process Services 1.6.0.

Best regards

Marco

When do you want to change process instance name?

The best would be using an Execution listener of the Sequence flow just before the first user task. Doing so I'd be able to modify the process instance name before the first user gets involved.

Thank you for your reply.
I made the sample for your use case.

Mmmhhh, as I wrote: this doesn't work. In my system modifications of the process name don't work before the end of the first user task.

Does it work for you?

I'm sorry, I didn't checked it in the same environment as you.
I checked it with Activiti engine 5.21.0.

Now, I checked it in the same environment as you(Alfresco Process Services 1.6.1) and got error as follows.

org.activiti.engine.ActivitiException: Unknown method used in expression: ${execution.getEngineServices().getRuntimeService().setProcessInstanceName(execution.getProcessInstanceId() , 'mod_name')}] with root cause
org.activiti.engine.impl.javax.el.MethodNotFoundException: Cannot find method 'getEngineServices' in 'class
‍‍‍‍‍

Probably, it seems that Alfresco Process Services limit EL expression, unlike Activiti Engine.
You can use modify process instance name by using an Execution listener(directly java program).

I made sample code and uploaded.

ah ok .. understood.

I was hoping that I could stay on the modelling site of the game but anyhow: thank you very much for the effort .. your help is most appreciated!

i tried setting the process instance name in the first user task listener, but it doesnt change the title, i have tried keeping this listener at multiple places but it seems to not change the header in the web.

has anyone tried and got results

Re: Modify process instance name

agnishu — Mon, 22 Jul 2019 06:58:45 GMT

it seems i can change the title by simply editing it before starting the process. but im still unable to retrieve the same during the execution. can someone help how can i retrieve the title during the execution? i tried to access all fields but no luck.

PS: the title we see in activiti-app whic usualu has format - "process name-current date"

Your solution works very well. But I have a question, is it possible to use a process variable in the process name? I tried to use a variable eg ${ClaimNumber} but unfortunately it doesn't work for me.

this may not be possible because the name is set just after the process start and h epocess insance might not be aware of this variable.

however if you started your process through Java code, then you can sart a process and immediately set a name of your choice. it can be a dynamic value passed from outside.

suppose "title" is a variable, you can create REST end point and execute this. you can then see this started process in the UI.

ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceByKey("someKey", variables);
processEngine.getRuntimeService().setProcessInstanceName(processInstance.getId(), title);
