Core Data Sorting on a Calculated field

Hi,

I am using iPhone OS 3.0 Core Data and the NSFetchedTResultsController.

All is great except i have an issue with sorting the data.

I have an event object that has a start date, it also has a relationship to another event.

How can i sort the events based on the start date or the start date on the related event.

What is the best strategy to achieve this, sort at the data level or sort at the table level?

please help

Simon
