In a presentation from before the new exporter, I used

* title 1
  - ...
  - ...

** goal 1:						      :BMCOL:B_block:
   :PROPERTIES:
   :BEAMER_env: block
   :BEAMER_col: 0.46
   :END:

   \( ... \)
** goal 2:						      :B_block:BMCOL:
   :PROPERTIES:
   :BEAMER_env: block
   :BEAMER_col: .54
   :END:

   ...

From reading up on this and searching the mailing list I was thinking
that with the new exporter this would have to be:

* title 1
  - ...
  - ...

** goal 1:
   :PROPERTIES:
   :BEAMER_env: block
   :BEAMER_col: 0.46
   :END:

   \( ... \)
** goal 2:
   :PROPERTIES:
   :BEAMER_env: block
   :BEAMER_col: .54
   :END:

But goal 1 & 2 come out in an enumeration. 

I have even been unable to get the example from
http://orgmode.org/worg/exporters/beamer/ox-beamer.html 
with the two columns to work.

Any hints?

Best regards,

Marko
