doc-view functions inside with-current-buffer do not work

[Alexander Baier]

Hello,

Consider the following steps:

- Define this function:
#+BEGIN_SRC emacs-lisp
  (defun my-doc-view-goto-page (n)
    (with-current-buffer (get-buffer "test.pdf")
      (doc-view-goto-page n)))
#+END_SRC

- C-x C-f test.pdf RET

- Evaluating the following snippet:
#+BEGIN_SRC emacs-lisp
  (my-doc-view-goto-page 2)
#+END_SRC

For me the buffer containing the test.pdf is still displaying the first
page of test.pdf. I expected it to show the second. Is this a bug?

Note: I waited for doc-view-mode to convert the whole pdf to png
images. At least the mode line displays "1/22" and does not change
anymore.

Regards,
