How to recover variables after the execution of the process?

[rodolfobarbeiro]

Hi!

I'm trying to retrieve the variables of a process that has no "waitState" task. But an error occurs because the process instance is already closed.

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processName, parameters);
         
Map<String, Object> variables =  runtimeService.getVariables(processInstance.getId());

‍‍‍‍‍‍

Is there any other way to recover the process variables?

Thanks!

How?

By reading the docs… e.g. chapter 10

I've seen the chapter 10, but could not use the example described.

My code:


ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processName, parameters);
  
List<HistoricDetail> historicList = historyService.createHistoricDetailQuery()
                                            .variableUpdates().processInstanceId(processInstance.getId())
                                            .orderByVariableName().asc().list();

But the list "historicList" is always empty.

I set the "History configuration" as audit, but the historic details are not stored in the database.
