I have several tables that are bound to models. All these models are

change to propogate to the 'higher' tables. Since, I am not
implementing the delegates of any table (all are connected via
bindings), the table reload their view only when I click on any one of
them.
Is there a "best way" of doing this?
It sounds like you are binding the tables directly to the model
objects. While you can do this, it's not generally recommended. You
will get much better results if you instead bind to one of the special
bindings controllers such as NSArrayController, which is the "normal"
method of using bindings.
I would highly recommend reading the Hillegass book as it describes
how to use bindings correctly.
