GUI callbacks empty?

I inherited a GUI from an ex-colleague. It was made with GUIDE and has 30 or so items, including a lot of boxes to enter numbers. This is my first foray into GUI programming (in any language), and I thought I was getting the hang of it until I realized that many of the callbacks contain no code. Is it possible that there's some other magic code getting executed somewhere that I can't see?

Right. It's a similar situation here. All the numbers feed into one action. But if it were up to me, I would convert the entered text into numbers immediately and store it in a suitable structure. On the other hand, I can't think of a good reason why the way it's written would be wrong.

There is certainly merit to having GUIs do field validation upon entering information -- verifying that a numeric field is convertable to a number for example.
The newer App Designer numeric edit fields are inherently for numeric values, and so reduce the need for validation.
