Hello,For a student project, we have to use a workflow engine. We have tasks to be validated by a system and I chose the Activiti Engine to create workflows.These tasks are performed one after the other and have three different statusesending, In progress and CompleteThe number of tasks is not fix

You can use task-variables for this. You can set a variable (eg. taskService.setVariableLocal("jobStatus", "pending") and retrieve it later or create queries that use that variable value…

Thanks I think it will be useful. Can i create variables for each task or this is only for a given process ?

I wish I could show a diagram of my workflow that shows its progress (show completed tasks, undone tasks,…), is there a way to get it back with all its tasks? (or do I have to use the bpmn model?)

Use the org.activiti.engine.impl.bpmn.diagram.ProcessDiagramGenerator for this, passing in the active activitId's to highlight. You can always pass in completed activityIds as well. Example extract from org.activiti.rest.api.process.ProcessInstanceDiagramResource


 ProcessDefinitionEntity pde = (ProcessDefinitionEntity) ((RepositoryServiceImpl) 
        ActivitiUtil.getRepositoryService()).getDeployedProcessDefinition(pi.getProcessDefinitionId());

    if (pde != null && pde.isGraphicalNotationDefined()) {
      BpmnModel bpmnModel = ActivitiUtil.getRepositoryService().getBpmnModel(pde.getId());
      InputStream resource = ProcessDiagramGenerator.generateDiagram(bpmnModel, "png", ActivitiUtil.getRuntimeService().getActiveActivityIds(processInstanceId));

      InputRepresentation output = new InputRepresentation(resource, MediaType.IMAGE_PNG);
      return output;
      
    } else {
      throw new ActivitiException("Process instance with id " + processInstanceId + " has no graphic description");
    }
[code]

Can you please let me know how i can mark a task as "InProcess" using activiti Rest API.
