How to assign a task based on NodeRef ?

upforsin

I want to create an action which uses authority.ftl  to pick a user and start a workflow.

How Can I create a simple pooled workflow and assign workflow task to this picked user? 

So far, I have this code:

protected void executeImpl(Action action, NodeRef actionedUponNodeRef) {
if (serviceRegistry.getNodeService().exists(actionedUponNodeRef) == true) {
   String assocString = (String) action.getParameterValue(PARAM_MY_ASSOC);   
   NodeRef nodePersonUser = new NodeRef(assocString);
   PersonInfo pi = serviceRegistry.getPersonService().getPerson(nodePersonUser);
   String username = pi.getFirstName();

   Map<QName, Serializable> properties = new HashMap<QName, Serializable>();
   WorkflowService workflowService = serviceRegistry.getWorkflowService();
   properties.put(WorkflowModel.ASSOC_ASSIGNEE, nodePersonUser);

   Serializable wfPackage = workflowService.createPackage(actionedUponNodeRef);
   properties.put(WorkflowModel.ASSOC_PACKAGE, wfPackage);
   properties.put(WorkflowModel.PROP_WORKFLOW_DESCRIPTION, "My action workflow");
   WorkflowDefinition reviewDef = workflowService.getDefinitionByName("activiti$activitiReview");
   workflowService.startWorkflow(reviewDef.getId(), properties)
}

There are no errors but there are also no items in the workflow tasks.

I got it. It didn't work because the assignee didn't have permission to see that particular file.

That line of code solves the problem:

serviceRegistry.getPermissionService().setPermission(actionedUponNodeRef, p.getUserName(), serviceRegistry.getPermissionService().COORDINATOR, true);
