How to store and retrieve process instance variable values in explorer tasks ?

[hari]

All,

I would like to know
1) How I can store the value to a process instance variable from a user task ?
2) How I can show the value of a process instance variable in a user task ?

I am using activiti explorer only. We are not implementing any custom forms or inboxes at this moment for our customer.

Thanks in advance.

Regards,
Hari.

3) To add to the above questions, I also want to understand how I can add process instance variables to my process which will be started by a user in the activiti explorer itself.

What I meant by questions 1 and 2 is when I have the process instance variables available in bpm, how I can store and retrieve values from them in explorer forms built using form properties.

Thanks,
Hari.

I found answer to my 2nd and 3rd questions. I have added a service task and have added the below code to it.

public void execute(DelegateExecution execution) throws Exception {
  execution.setVariable("hari", "Hari");
}
This way I was able to show the process variable information on the activiti-explorer.

I am still trying to find answer to my question#1.

Hi Hari,

have a look on org.activiti.engine.test.api.task.TaskServiceTest#testCompleteWithParametersTaskin activiti source.

Hi Martin,

The task will be completed by the user in activiti-explorer.
My goal is to capture the users input into a process instance variable.

Thanks,
Hari.

All form values are stored as process variables, so putting them on the form automatically makes it a process variable.
