A problem with eval-after-load

[Marcin Borkowski <mbork@wmi.amu.edu.pl>]

Hi all,

I have a problem with eval-after-load.  (In fact, this is one of the
reasons I subscribed to this list;).)  I have something like this in my
init.el:

(eval-after-load 'org-tree-slide '(setq org-tree-slide-mode-map
  (let ((map (make-sparse-keymap)))
    (define-key map (kbd "<f1>") 'org-tree-slide-content)
    (define-key map (kbd "<f5>") 'org-tree-slide-move-previous-tree)
    (define-key map (kbd "<f8>") 'org-tree-slide-move-next-tree)
    map)))

(load-file "~/some/path/org-tree-slide/org-tree-slide.el")

The rationale is that I did not like the default keybindings of
org-tree-slide (which is an Org-mode based simple presentation tool).

The problem is that this doesn't work: the keymap is not updated.  When
I load the org-tree-slide.el *manually*, somehow it gets updated.  (It
is a bit embarassing that I noticed it before I posted this blog post:
<shameless plug>
http://mbork.pl/2013-10-09_Better_keymap_for_org-tree-slide
</shameless plug>,
but I didn't notice this at first.  I will update the said post as soon
as I understand what's going on here.)

Of course, I could just get rid of eval-after-load and change the order
of the loading and redefining the keymap - but I want to know what's
the problem.  (Initially, I didn't want to load org-tree-slide by
default, hence the eval-after-load stuff.  Then, I decided it won't
hurt to have it loaded always.  I should probably learn to use
autoload.)

Am I doing something wrong?

(PS. org-mode-slide.el *does* say (provide 'org-tree-slide).)

Best,
