user labels in beamer export

I am having problems trying to use user defined labels in org export to
LaTeX (beamer specifically).

If I have the following org,

#+begin_src org
  ,#+TITLE: LaTeX export minimal test
  ,* Intro
  :PROPERTIES:
  :CUSTOM_ID: introduction
  :END:
  This is the first slide.
  ,* Summary
  As we saw on slide [[#introduction]], ...
#+end_src

I get the following LaTeX generated:

#+begin_src latex
  \begin{frame}[label=introduction]{Intro}
  This is the first slide.
  \end{frame}

  \begin{frame}[label={sec:orgdc0a2c3}]{Summary}
  As we saw on slide \ref{sec-1}, \ldots{}
  \end{frame}
#+end_src

(elided for size).  Note that internally generated labels of the form
orgXXXXXX are not generated but instead org generates "sec-1" instead of
using \ref{introduction}.

I have org-latex-prefer-user-labels set to t.

Am I doing something wrong or is this a bug in org?  I'm up to date with
git version as of a few minutes ago.

Thanks,
eric

The latter. I fixed it on maint. Thank you.

Thank you!  This now works (using CUSTOM_ID).

Now for another related question.  Should the following work?

#+begin_src org
  ,#+TITLE: LaTeX export minimal test
  ,* <<introduction>> Intro
  This is the first slide.
  ,* Summary
  As we saw on slide [[introduction]], ...
#+end_src

I get this LaTeX code in this case, again with
org-latex-prefer-user-labels set to t.

#+begin_src latex
  \begin{frame}[label={sec:org3f12c9c}]{\label{org9590917} Intro}
  This is the first slide.
  \end{frame}
  \begin{frame}[label={sec:orgfd595e1}]{Summary}
  As we saw on slide \ref{introduction}, \ldots{}
  \end{frame}
#+end_src

Should probably have asked both questions at the same time but did not
want to confuse the issue!

Thanks again,
eric

Hi Nicolas,

this doesn't seem to work still.  I've updated my copy of org and I get
the following on beamer export:

#+begin_src latex
  \begin{frame}[label={sec:orgb78d808}]{\label{org5b96364} Intro}
  This is the first slide.
  \end{frame}
  \begin{frame}[label={sec:org07fd86c}]{Summary}
  As we saw on slide \ref{introduction}, \ldots{}
  \end{frame}
#+end_src

Thanks,
eric

Thanks!  Hopefully that's it for now.  Or, at least, with respect to
links and targets.  :-)
