I never dreamed such a task could cause such difficulty!

I'm making a custom cell that will 'animate' in a sense. Each of these cells holds an NSTimer. The object value sets a bool that determines whether the code inside the timer's method is executed or not. The code in this method simply increments a value and requests the table view to redraw. So the object value effectively starts and stops the animation.

Well, in the montage of problems that arose from this, I found out more about how cells work, but I'm still confused. It took me forever to discover that the weird problems with bindings I was experiencing stemmed from the fact that there is ONE cell for a table column, that it uses to draw all its data.

Through google, I read about implementing -copyWithZone:, but breakpoints in this method never get called...

I tried overriding table column's -dataCellForRow: and returning a new cell [[MyCell alloc] init]. This, however, apparently causes infinite cells to be allocated, and a crash happens.

In short, a value change that should affect one cell affects all of them. Some magic is happening in Apple's cell classes that makes values affect only the intended cell. Sorry if I'm missing something obvious here... but I'm completely stumped.
