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
