I accomplished the task with bindings by adding a 'total' method to my Transaction class that called from the text field's binding using @sum.total. But now how can I make it update without having to add or remove from the data set in the nstableview? (It only updates when I add or remove a new transaction)

Hello list,

I am trying to learn Cocoa from a Java background. Currently reading Hillegass's "Cocoa Programming" but I need some pointers that he doesn't specifically mention.

I am writing a simple ledger program that relies on an NSTableView for display. Via the chapter on binding I am using an NSArrayController to take care of all the data management. My dilemma is that I need to keep a single text field updated with the current balance of an account. Can I do this using bindings also, or should I use notification? I'm really at a loss of where to go from here. TIA
