Adding users to a process role at runtime method :- addRuntimeDefinedUser

Hi All,

I have a requester - approver process where I want to assign list of users to Processor for Approval role.

I am getting list in requester CO and at design-time I have declared Processor for Approval as runtime defined in roles tab of process.

Can anybody tell me how to add this users to this role programmatically? may b in execute method or in complete() method?

I came across with one method which looks promising :

IGPRuntimeManager rtManager = GPProcessFactory.getRuntimeManager();

rtManager.addRuntimeDefinedUser();

This method requires IGPProcessInstance and other parameters. Can I get some info abt how to get them?

Sample code will be most welcome.

Thanks and regards,
