Assign tasks automatically when vacation set for a user

Question

Hi,
I've a requirement where user can set the vacation period and rules. When the vacation period starts, all the tasks already assigned to him should get REASSIGNED AUTOMATICALLY to the other user that we configured in the vacation rule. How can I achieve this? Please suggest me some ideas.
Thanks

Hi Bill,
I am able to reassign/delegate the task to a SINGLE user programmatically using the below code.
private void vacationTask(String taskAction) {
String errorMessage = "Below users are not valid: ";
boolean isFirstInvalidUser = true;
FacesContext facesContext = FacesContext.getCurrentInstance();
FacesMessage facesMessage = null;
try {
String contextStr = ADFWorklistBeanUtil.getWorklistContextId();
IWorkflowServiceClient wfSvcClient = WorkflowService.getWorkflowServiceClient();
ITaskQueryService querySvc = wfSvcClient.getTaskQueryService();
ITaskService taskService = wfSvcClient.getTaskService();
IWorkflowContext ctx = querySvc.getWorkflowContext(contextStr);
String loggedInUser = ctx.getUser();
List queryColumns = new ArrayList();
queryColumns.add("TASKID");
queryColumns.add("TASKNUMBER");
queryColumns.add("TITLE");
queryColumns.add("OUTCOME");
List tasks = querySvc.queryTasks(ctx,queryColumns,null,ITaskQueryService.AssignmentFilter.MY,null,this.getTaskPredicate(),null,0,0);
ITaskService taskSvc = wfSvcClient.getTaskService();
for(int i = 0 ; i < tasks.size() ; i ++) {
Task task = (Task)tasks.get(i);
String title = task.getTitle();
String taskId = task.getSystemAttributes().getTaskId();
String userInputList = null;
String[] usersList = null;
if(this.getUserToAssign().getValue() != null) {
userInputList = (String) this.getUserToAssign().getValue();
usersList = userInputList.split(",");
} else {
facesMessage = new FacesMessage("No users list provided. Please provide atleast one userId to reassign the task(s). ");
facesContext.addMessage(null, facesMessage);
return;
for(int j=0; j<usersList.length; j++) {
String userToAssign = usersList[j];
userToAssign = userToAssign.trim();
if(userToAssign!=null) {
UserBean userBean = new UserBean();
boolean isUserValid = userBean.isValidUser(userToAssign);
if(isUserValid) {
List<TaskAssignee> assignees = new ArrayList<TaskAssignee>();
TaskAssignee assignee = new TaskAssignee(userToAssign, IWorkflowConstants.IDENTITY_TYPE_USER);
assignees.add(assignee);
if(taskAction.equals(TASK_ACTION_REASSIGN)) {
taskSvc.reassignTask(ctx, taskId, assignees) ;
this.getConfirmMsg().setValue("The task(s) have been reassigned");
else if(taskAction.equals(TASK_ACTION_DELEGATE)) {
taskSvc.delegateTask(ctx, taskId, assignees);
this.getConfirmMsg().setValue("The task(s) have been delegated");
} else {                       
if(isFirstInvalidUser)
errorMessage = errorMessage + " " + userToAssign;
else
errorMessage = errorMessage + ", " + userToAssign;
isFirstInvalidUser = false;
if(!isFirstInvalidUser) {
facesMessage = new FacesMessage(errorMessage);
facesContext.addMessage(null, facesMessage);
} else {
this.getConfirmationPopup().show(new RichPopup.PopupHints());
catch (Exception e) {
//Handle any exceptions raised here...
System.out.println("Caught workflow exception: "+e.getMessage());
But, when I supply multiple uses separated by comma(,), the tasks are being assigned to the last user ONLY. Any idea why its happening.
Thanks.
