It's certainly possible to use popup buttons in a table column.
It's questionable whether this is the right tool for this job. Popup buttons
aren't great at showing multiple selections -- except when their menu is
actually popped up, of course. It's irritatingly harder (though not exceedingly
hard) to force the button to display a title that isn't the same as the
(single) selected item.
And what title to display? That's a significant problem, especially if "there
might be twenty [actions] in the future".

What do you mean by "bound"? Are you using a Cocoa binding, or do you just mean
you've connected the "selector" connection from the cell to some target?

I dunno, but table views do things to cells that you might not always expect.
If you set a breakpoint in your 'cellPreferenceChanged' method, what does the
backtrace look like?
