Start another workflow from a service task of a workflow

[stondini]

Hello,

I'd like to start a workflow from another workflow without using <em>callActivity</em> element because I'd the first workflow ends.
If I use <em>callActivity</em> element, the first workflow will wait the end of the second one.

I need two independent workflows.

Here, the service task of the first workflow :

    <serviceTask id="incomingClientDocument" name="Client Workflow" activiti:class="org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate">      <extensionElements>        <activiti:field name="script">          <activiti:string><![CDATA[                                                logger.log('incomingClientDocument-START');                  var clientNodeRef = execution.getVariable('rtcm_clientAssoc');                  var dueDate = execution.getVariable('bpm_workflowDueDate');                                                // Here, the second workflow starts…                  rtTaskService.startIncomingClientDocument(clientNodeRef, bpm_package, dueDate);                  logger.log('incomingClientDocument-END');           ]]></activiti:string>        </activiti:field>      </extensionElements>    </serviceTask>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And here the Java code of <em>rtTaskService.startIncomingClientDocument()</em>

  public void startIncomingClientDocument(final ScriptNode clientNode, final ScriptNode packageNode, final Date dueDate) {    logger.info("Start Incoming Client Document Workflow");    NodeService nodeService = this.getServiceRegistry().getNodeService();    WorkflowService workflowService = this.getServiceRegistry().getWorkflowService();    ClientEntity clientEntity = new ClientEntity(getServiceRegistry(), clientNode.getNodeRef());    // Create a package that contains the items of the source package    NodeRef packageNodeRef = workflowService.createPackage(null);    if (packageNode != null) {      for (ChildAssociationRef childRef : nodeService.getChildAssocs(packageNode.getNodeRef()))        nodeService.addChild(packageNodeRef, childRef.getChildRef(), WorkflowModel.ASSOC_PACKAGE_CONTAINS,            QName.createQName(NamespaceService.CONTENT_MODEL_PREFIX, "incomingClientDocument"));    }    WorkflowDefinition workflowDefinition = workflowService.getDefinitionByName("activiti$IncomingClientDocument");    Map<QName, Serializable> parameters = new HashMap<QName, Serializable>();    parameters.put(WorkflowModel.PROP_WORKFLOW_DESCRIPTION, "Incoming Client Document");    parameters.put(WorkflowModel.PROP_WORKFLOW_DUE_DATE, dueDate);    parameters.put(WorkflowModel.PROP_DUE_DATE, dueDate);    parameters.put(WorkflowModel.ASSOC_GROUP_ASSIGNEE, clientEntity.getGroupAuthorityName());    parameters.put(WorkflowModel.ASSOC_PACKAGE, packageNodeRef);    parameters.put(ClientRelatedContentModel.ASSOC_CLIENT, clientNode.getNodeRef());    workflowService.startWorkflow(workflowDefinition.getId(), parameters);  }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

When I execute the first workflow, it raises the following error :

Error while completing sub process of execution ProcessInstance[92626]‍‍‍

Do you have an idea of what is wrong ?

Thank you.

Hi,

You need add few more lines to your Java code after start workflow. As below

 WorkflowPath path = workflowService.startWorkflow(workflowDefinition.getId(), parameters); String wfPathId = path.getId(); List<WorkflowTask> wfTasks = workflowService.getTasksForWorkflowPath(wfPathId); if (wfTasks.size() == 0)return; WorkflowTask wfStartTask = wfTasks.get(0); workflowService.endTask(wfStartTask.getId(), null);‍‍‍‍‍‍‍‍
