A follow up question: how do I now sort the data in the table? I am showing three values in the table, and like to sort based on either one of them. The original data is in an unordered NSSet (from my CD model). I could create an NSArray in my view controller: NSArray *myArray = [myTagsSet allObjects], and bind that to the NSArrayController, instead of to the NSSet; then I can sort the values in the table based on the array using sortDescriptors as explained here: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TableView/SortingTableViews/SortingTableViews.html#//apple_ref/doc/uid/10000026i-CH10-SW1.
Would that be a good approach?
Other alternatives?
OSX, 10.7.
Thanks,
- Koen.

The table should display various attributes of the entity 'Tags', which has a many-to-one relationship with my main entity. In my code I can see that the Tags entities are valid using NSLog statements, however I fail to use the correct binding to hook it up to the table. From the docs (at <https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html#//apple_ref/doc/uid/10000026i-CH13-SW1>), I see I need to bind the table to an NSArrayController, however, my Tags are an NSSet.
