[xmonad] Is this a bug in ManageHook? (Spaces in composeAll)

[Christian Walther]

Hi,

I'm currently using xmonad 0.8.1 compiled with ghc-6.8.3 on NetBSD
5.0.1 i386, after migrating from FreeBSD i386.
After building all the software I needed/wanted, including Firefox and
Pidgin, I noticed that not all windows where sent to the right
workspace I configured them for. I noticed (or at least I thought)
that some xprops changed, and I edited myManageHook to contain:

myManageHook = composeAll
    [ title     =? "Buddy List"            --> doF (W.shift "9")
    , className =? "Gran Paradiso"         --> doF (W.shift "8") ]

(And some more, of course...)

This has some interesting side effect, because every time I start
either Firefox or Pidgin and their window appear on workspace 8 or 9,
the window that has the focus is sent to exactly the same workspace,
too.
Commenting out both entries fixed this issue. Since they aren't needed
(which is a perfect example of why working on a computer when being
tired is a bad idea) this is just a minor issue. But I wonder if this
behavior due to the nature of composeAll or something in Haskell I'm
unfamiliar with (which is, at present, most of the language).
