I have a table with data in it. When someone clicks the remove button, I get the selection array and remove all the objects in it. If there is an empty selection, I am told index out of bounds, naturally, because there are no items in the array. Can I just leave this error? Or should I make a catch for it?

Are you using bindings? If so, you can bind the button's "enable" property to the array controller's "canRemove" key. In addition to avoiding the problem, it gives the user positive feedback; the delete button will only "light up" when something is selected.
