org-e-beamer-exporter and frame level

Hi,

It seems to me that in the 7.9 release and the current git version,
org-e-beamer exporter breaks whenever I change the org-e-beamer-frame-level
to something else than 1.
The variable BEAMER_FRAME_LEVEL seems not to be honoured anymore. If I set
H:2 in OPTIONS, parsing breaks. If I set org-e-beamer-frame-level to 2,
parsing breaks too.
Can anyone confirm ?

Correct. It has been replaced by H:2 in #+OPTIONS: or
`org-e-beamer-frame-level'.

I get no error when using `org-e-beamer-export-to-pdf' on the following
code:

--8<---------------cut here---------------start------------->8---
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: default
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
#+OPTIONS: H:2

Do you have an appropriate "beamer" entry in `org-e-latex-classes' ?

Mine is:

--8<---------------cut here---------------start------------->8---
(add-to-list 'org-e-latex-classes
             '("beamer"
               "\\documentclass\[presentation\]\{beamer\}
\[DEFAULT-PACKAGES]
\[PACKAGES]
\[EXTRA]"
               ("\\section\{%s\}" . "\\section*\{%s\}")
               ("\\subsection\{%s\}" . "\\subsection*\{%s\}")
               ("\\subsubsection\{%s\}" . "\\subsubsection*\{%s\}")))
--8<---------------cut here---------------end--------------->8---

Ok ... I used this :

(add-to-list 'org-e-latex-classes
    '("beamer" "\\documentclass{beamer}
                     [NO-DEFAULT-PACKAGES]
                     [NO-PACKAGES]"
        org-beamer-sectioning))

And thought it would work, but obviously, org-beamer-sectioning doesn't
behave the right way.

Thanks for the explanation.

And the problem comes from this.

In org-e-beamer.el:1325
(defun org-e-latex-headline (headline contents info)
  "Transcode an HEADLINE element from Org to LaTeX.
CONTENTS holds the contents of the headline.  INFO is a plist
holding contextual information."
  (let* ((class (plist-get info :latex-class))
 (level (org-export-get-relative-level headline info))
 (numberedp (org-export-numbered-headline-p headline info))
 (class-sectionning (assoc class org-e-latex-classes))
 ;; Section formatting will set two placeholders: one for the
 ;; title and the other for the contents.
 (section-fmt
  (let ((sec (if (and (symbolp (nth 2 class-sectionning))
      (fboundp (nth 2 class-sectionning)))
 (funcall (nth 2 class-sectionning) level numberedp)
       (nth (1+ level) class-sectionning))))

The funcall occurs on #'org-beamer-sectioning with argument level=2 and
numberedp=t
but the function #'org-beamer-sectioning (org-beamer:232) takes 'level' and
'text' as arguments, 'text'
being the contents of the headline.
