The difference between an active and a passive delegate lies in the messages they use
to fill the browser with data. Thus, there's no guarantee that cells will be loaded on
demand for a passive delegate, so this isn't a bug.
While it would be nice to be able to do this, it isn't easy to implement, and I don't
see any way of doing it that doesn't involve slightly changing the interface towards
custom matrix/cell classes. The most tempting alternative would be to extend NSMatrix
to let you create cells on demand and then use this from NSBrowser (this is also the
only alternative that avoids creating tons of browser cells up-front).
Anyway, in the absence of something that depends critically on this, or (really good)
patches that implement it, I don't think I'll look more at it; not enough benefit for
the complexity and effort.
I don't really know what we want our policy to be for things like this; for now, I'll
leave it open as a "Change request".

Summary: NSBrowser loads all cells for passive delegate
Original Submission: When using NSBrowser and a passive delegate (numberOfRows... and
willDisplayCell:...), the browser loads all cells. This makes no difference between
the passive and the active delegate.
In my application i have a column with 1000+ items (cells), and they are all loaded
instead of just a few (say 5-10) that are going to be displayed.
I have tested this with rIO's HelpViewer and got the same result.
