You shoul post your code as it is difficult to discern your problem with the way you are describing things. In other words: Cannot perform operation without a managed object context What operation is being performed that could require an moc? If I set a breakpoint: In what, on what?

Quick question about adding an NSPanel

Hi, I have a quick question about adding an NSPanel to an app. I'm following Hillegass's book, so I have a separate controller and nib for the panel. I added an IBAction (showSettingsPanel:) to my main app controller and hooked it up to the Preferences... menu item. Works great. This is

Forcing controller to update binding of compound value

I'm using bindings to display values in a table. I use an array controller bound to the attribute of a model object. The controller "handles content as compound value" because of the way I access and update the content from a larger set. Everything is great in that values are retrieved a
