Yes, now appears. Now I have a new problem, whenever I create some events, and then I click on the calendar or refresh the calendar, the date of the events just changes, I don't know why, can you help me?

can you provide a new oml with the changes you made?

Sure!

Thank you João,

So, you have an assign with the 'AddDays' function in your 'FullCalendarEventMouseEnter' action. This is changing your event dates, since you have a CreateOrUpdate later.

Also, you have a lot of warnings that you should consider dealing with, specially the 'OnInitialize' ones. Hope this helps

Another thing, this assign is changing both start and end date of the events. Since the events can have null end date, you should always validate if you have a value there, or you'll be changing what the user entered
