I apologize in advance for subjecting the list members to another CoreData 
model description. To ease the pain here is a screen shot of the datamodel.

http://codemuster.co.nz/images/datamodel.jpg

The plan is to build a 10.7, document based, CoreData app that stores,sorts and 
displays scores from clay target events around the country. It will be used to 
select the national teams.

Simply put a Competition entity can have multiple Events and multiple Entries. 
An Entry can have multiple EventScores but may not have an EventScore for every 
Event. Event is also connected to eventScores.

I have a 3 level master/detail view. I am currently using 3 tableViews, the 
first one is bound to the competitionsArrayController arrangedObjects.name The 
second tableView is bound to the selectedCompetition.entries arrayController 
arrangedObjects.shooter.name

The third tableView has 2 tableColumns. The first tableColumn's arrayController 
is bound to competitionsArrayController.selection.events and displays all the 
event names in the first column.

How do I display the EventScores for selected Entry in the second column?

Thanks in advance

Rob
