Hello, I'm trying to add a duration to a Start Date to produce an End Date. (Meeting starts at 12:00, duration = 2 hours, End Date should show 14:00) Looking in the API, I could find the following Xpath: addHours(dateTime($.../StartDate), $.../Duration) Where Start Date is Date and time, and Duration is Integer. Entering this in the Xpath, it returns the following error: Line: 1 Column: 10 Error: The function 'dateTime' takes one to seven literal Integers. I'm fairly new to Mendix, so it's probably something simple. Kind Regards,
The example for addHours in the documentation is as follows:
addHours(dateTime(2007, 1, 1, 1, 1, 1), 25)
However, in your case, it seems like you have an attribute that is already a datetime value, lets call it $Meeting/StartDate. So for this, you would use addHours as follows: addHours($Meeting/StartDate, 2) This would add 2 hours to the start date. the dateTime(2007, 1, 1, 1, 1, 1) function call will take those integer arguments and return a date (Jan 1 2007 in this case.
