thanks for the answer, the coding style is one thing, and i don't have
the least bit of a problem to stick with this in the future (already
changed all the occurrences anyway to make it work again).

what i'm worried about is wether i did break anything else, possibly
with even worse results... (i don't like hidden bugs)

btw. is it also bad practice to use self.REQUEST in methods?
what about def foo(self, REQUEST=None), when and how is REQUEST
passed there? is it also not a good coding style, if not passing it directly?
