new exporter: exporting subtree as beamer

[Andreas Leha <andreas.leha@med.uni-goettingen.de>]

Hi all,

I am having trouble to export a subtree as beamer document with the new
exporter.  (Org-mode version 7.9.1 (release_7.9.1-316-g66fe32)

Here is a simple org-document, that was prepared for beamer export using
org-e-beamer-insert-options-template:


----[ test_beamer.org ]
 * Test Beamer
   :PROPERTIES:
   :EXPORT_LaTeX_CLASS: beamer
   :EXPORT_LaTeX_CLASS_OPTIONS: [presentation]
   :EXPORT_FILE_NAME: presentation.pdf
   :COLUMNS:  %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col) %8BEAMER_opt(Opt)
   :BEAMER_col_ALL: 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
   :END:
 
 ** First Slide							    :B_frame:
    :PROPERTIES:
    :BEAMER_env: frame
    :END:
    - first bullet
----



And this is what I get when I export the subtree "Test Beamer" as
beamer:

What am I missing here?
