Hi,

I am using Scheduling API to create a "crontab" task. The problem is that the code is never executed.

From I sitefinity custom widget (inherits SimpleView) I am creating scheduled task with execution time after 5 mins:

Widget Code:

private void TheButton_Click(object sender, EventArgs e)

RssFeedScheduledTask theRssTask = new RssFeedScheduledTask();

theRssTask.ExecuteTime = DateTime.UtcNow.AddMinutes(5);

theRssTask.Title = "RssFeedScheduledTask";

theRssTask.Description = "Crontab tab";

theRssTask.ScheduleSpec = "5 * * * * *";

theRssTask.ScheduleSpecType = "crontab";

theRssTask.IsRecurring = true;

this.scheduleManager.AddTask(theRssTask);

//SchedulingManager.RescheduleNextRun();

this.scheduleManager.SaveChanges();

this.BindRepeater();

The scheduled task code:

public class RssFeedScheduledTask : ScheduledTask

private const string TaskKey = "F5C8088A-992D-4969-ABC7-5C1AE4B9EB78";

private const string TaskNameText = "RssFeedTask9";

public RssFeedScheduledTask()

this.Key = TaskKey;

public override void ExecuteTask()

var newsManager = NewsManager.GetManager();

var newsItem = newsManager.CreateNewsItem();

newsItem.Title = "Scheduled task";

newsItem.Description = "Scheduled task description";

newsItem.Content = "Scheduled task Content";

newsItem.DateCreated = DateTime.UtcNow;

newsItem.LastModified = DateTime.UtcNow;

newsItem.PublicationDate = DateTime.UtcNow;

newsItem.UrlName = "scheduled-task";

newsManager.RecompileAndValidateUrls(newsItem);

newsManager.SaveChanges();

var bag = new Dictionary<string, string>();

bag.Add("ContentType", typeof(NewsItem).FullName);

WorkflowManager.MessageWorkflow(newsItem.Id, typeof(NewsItem), null, "Publish", false, bag);

public override string TaskName

get

return TaskNameText;

protected override bool CanReschedule()

return true;

Docs: docs.sitefinity.com/.../for-developers-scheduled-tasks

Articles: www.sitefinity.com/.../how-do-i-create-a-reoccuring-scheduled-task

and I've read other knowledgebase articles - didn't help.

Sitefinity version 8.1.5824.0

The issues that I've detected so far:

The method ExecuteTask() of my task is never executed
After the execution date-time passed, the "IsRunning" is true and the "status" is started
The task isn't rescheduled for next time

Why the ExecuteTask() is never executed ?

Any help is appreciated.

I have experience with Scheduling API is another SF project 9.2 Version and it works with no problems.
