Hi all,

I have the following problem:

I have set up my emacs so as to use org-mode uncompiled from a local directory

# from .emacs
(setq load-path (cons "~/elisp/org-mode/lisp" load-path))
(setq load-path (cons "~/elisp/org-mode/contrib/lisp" load-path))


starting emacs22 or 23 and displaying M-x org-version I get:

Org-mode version 6.35trans (release_6.35g.207.g7f085)

so indeed the version from the local directory.

when I take a document with the following preamble:

#+LaTeX_CLASS: beamer
#+TITLE:     present.org
#+AUTHOR:    Erik
#+EMAIL:     erik@eddie
#+DATE:      2010-04-08 Thu
#+DESCRIPTION:
#+KEYWORDS:
#+LANGUAGE:  en
#+OPTIONS:   H:3 num:t toc:t \n:nil @:t ::t |:t ^:t -:t f:t *:t <:t
#+OPTIONS:   TeX:t LaTeX:nil skip:nil d:nil todo:t pri:nil tags:not-in-toc
#+INFOJS_OPT: view:nil toc:nil ltoc:t mouse:underline buttons:0
path:http://orgmode.org/org-info.js
#+EXPORT_SELECT_TAGS: export
#+EXPORT_EXCLUDE_TAGS: noexport
#+LINK_UP:
#+LINK_HOME:

and export this to latex I get the following:


\documentclass[11pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage{hyperref}


\title{present.org}
\author{Erik}
\date{2010-04-08 Thu}

\begin{document}

\maketitle

\setcounter{tocdepth}{3}
\tableofcontents


\end{document}

so despite the #+LaTeX_CLASS: beamer, the document gets exported as
'article'. Even worse, when I try to export the same document again
afterwards, I get a:
No definition for class `beamer' in `org-export-latex-classes'

error.

When I issue a 'reload-org-uncompiled' directly after starting emacs,
this behavior does not occur.

In this case I get, as expected:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{fixltx2e}
\usepackage{graphicx}
\usepackage{longtable}
\usepackage{float}
\usepackage{wrapfig}
\usepackage{soul}
\usepackage{t1enc}
\usepackage{textcomp}
\usepackage{marvosym}
\usepackage{wasysym}
\usepackage{latexsym}
\usepackage{amssymb}
\usepackage{hyperref}
\tolerance=1000
\providecommand{\alert}[1]{\textbf{#1}}

\title{present.org}
\author{Erik}
\date{2010-04-08 Thu}

\begin{document}

\maketitle

\begin{frame}
\frametitle{Outline}
\setcounter{tocdepth}{3}
\tableofcontents
\end{frame}

\end{document}


any hints appreciated on how this behavior comes about.

Cheers,

Erik
