Rui, Generally you don't use the "data source" method of filling up an NSTableView when you use Core Data. Doing so would require you to observe changes to the Managed Object Context, and reload the table manually. Instead, you would usually use an NSArrayController in your NIB instead, and use bindings. This is explained in more detail in Aaron Hillegass's book, a great one and one that I recommend for beginners, called something about starting with Mac OS X development, or something. It's pretty famous around these here parts, I'm sure you can find it somewhere. But remember, use NSArrayController, not manual bindings, when using Core Data. (Usually.)
