I masochistically downloaded your project, and I think it’s a perfect example of why not to do this. There is so much glue code that it's impossible to tell whether your code is any more than locally correct (that is, beyond whether each line of code does what it purports to do). But all that aside… — I think it’s a tragic mistake to subclass a NSArrayController. The class is a largely inscrutable black box of glue code, and any code that you add is thrown into the black hole. (I admit this is only an opinion. Others may love this kind of self-inflicted pain.) — I think it’s *probably* a mistake to use NSArrayControllers *at all* in this project, where you’re trying to implement a specific UI. A NSArrayController is a generalized collection of behaviors intended to be used to support a large generality of UI designs in a NIB file. That level of generality isn’t necessary when you’re writing UI code directly, without using NIBs. It’s the equivalent of using a dictionary with string keys to represent properties, instead of declaring the actual properties you want. — Your actual problem is that selection doesn’t work because you didn’t connect up the right pieces to make it work. For example, I fixed it for the first table by adding one line of code in the “buildGUI” method: > [combatantsTable bind: @"content" toObject: self.combatantsController > withKeyPath: @"arrangedObjects" options: 0]; // existing code > [combatantsTable bind: @"selectionIndexes" toObject: > self.combatantsController withKeyPath: @"selectionIndexes" options: 0]; // > added code IOW, the array controller doesn’t know what the current selection is unless you tell it. I didn’t try to fix any of the other tables, but presumably they have the same problem. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
