hook to set point in article buffer?

hook to set point in article buffer?

[jari.aalto]

    Hi,

    What hook should I use to position the point in article buffer?
    I have some automated messages that are sent to me and I'd
    like to position point to "error message" when I select the 
    article

    I looked briefly the *article* hooks, but there seem to be 
    run inside save-excursion and that means...you know.

Yes, that means that you should use `set-window-point', we know.

I take it you have tried?

Here's two examples:

(save-excursion
  (set-buffer (get-buffer "*Help*"))
  (set-window-point (get-buffer-window (current-buffer)) (point-max)))

(save-excursion
  (set-buffer (get-buffer "*Help*"))
  (goto-char (point-max)))

(It helps if you have point at point-min in the *Help* buffer (and
that it exists, of course.)

|   (set-window-point (get-buffer-window (current-buffer)) (point-max))

I tried putting this anywhere I could think of

        gnus-article-prepare-hook
        gnus-select-article-hook
        gnus-article-display-hook

And I verified that point moved when the hook run at that point 
but when the article display was completed, the point was always
at point-min. Next I looked what was going on and did

    (defadvice gnus-article-set-window-start  (around my  act)
      "Disable function so that point can be set in buffer.")

and now the point can be changed with set-window-point in
gnus-select-article-hook. Please tell if there is another way
without the advice code.
