Restart the workflow from the desired step

[chandanmb1]

Hello,

Assume i have a workflow

Start -> Task 1 -> Task 2 -> Task 3 -> End
We should not change the Workflow Template.

Now i am in the middle of execution of Task 2. User from GUI will choose restart from Task 1.
When Task 2 completes and during the start of Task 3, i should check whether user has told to restart.

If yes, i need to go back to Task 1 and again start the execution from Task 1.
I shouldn't execute Task 3

Is such scenarios can be handled in Java ?

Task could be of any kind (Service Task/User Task)  which ever you suggest for our business use case. I will use that.
But we need to achieve this scenario.

Any idea ?

Regards,
Chandan

Hi,

Just set activityId in the execution to the desired one. (You have to know what you are doing - activiti can create several executions for one process instance)

Hello Martin,

In activiti community edition, Are you parsing the XML  to execute flows ?
If yes, please provide me the classname ? Also, if i can reuse the same for customization

Hello,

@Override
public void notify(DelegateTask delegateTask) {
 
  DelegateExecution execution = delegateTask.getExecution();
 
 
  EngineServices engineServices = execution.getEngineServices();
  TaskService taskService = engineServices.getTaskService();
  String userCommand=execution.getVariable("Command").toString();
 
  if(userCommand.equalsIgnoreCase("STOP")){
   System.out.println("User has issued the Stop command and I will not execute the further process:::::::"+userCommand);
  
   ExecutionEntity executionEntity=new ExecutionEntity(); // Is it the right way of using ExecutionEntity
   executionEntity.setActivity(activity);   // from where i will get the value of activity ?
   taskService.complete(delegateTask.getId());
  
  
  }
}
