Subject: find_all wierdness

My problem is as follows:

book.chapters.find_all{ |chapter| !chapter.pages.empty? }.size

Theoretically it should return a number of chapters that have pages in 
them. However it doesn't do that at all. It simply returns a number of 
all chapters.

On the same note:

book.chapters.find_all { |chapter| chapter.pages.empty? }.size returns 
the same thing as above.

Identically

book.chapters.find_all { |chapter| 1 == 2 }.size still returns same 
thing (shouldn't that be zero now???)

And finally

book.chapters.find_all{ my ass }.size  returns exactly the same thing!!! 
Seems that whatever is in brackets is simply ignored.

Any ideas why it does that? BTW, it seems to work just fine for 
numerical arrays.

Thanks.
