# “missing item” in article mode using automatic uncover [beamer]

I tried to use the automatic uncover option (beamer user guide, section 23.1) as follows:

% file test.tex

\begin{document}

This is a test.
\begin{frame}
\begin{itemize}[<+->]
\item First
\item Second
\end{itemize}
\end{frame}


% file test.beamer.tex to produce the actual presentation; works as expected.

\documentclass[ignorenonframetext]{beamer}
\input{test.tex}


% file test.article.tex

\documentclass{article}
\usepackage{beamerarticle}
\setjobnamebeamerversion{test8.beamer}
\input{test8.tex}
\end{document}


which gives the following error:

! LaTeX Error: Something's wrong--perhaps a missing \item.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
...

l.6      \item F
irst


The actual presentation has a lot of lists of items, making the automatic uncovering most desirable. Any suggestion would be greatly appreciated.

This is 'works for me' (it should do: I fixed the bug!). Which version of beamer do you have? –  Joseph Wright Dec 14 '11 at 19:05
@Joseph-Wright This is from the TeXLive2011 distribution... The most recent entry in the ChangeLog reads: changeset: 441:208bcd589060 tag: tip user: Vedran Miletiƒá <rivanvx@gmail.com> date: Mon Jul 12 19:35:36 2010 +0200 –  André Dec 14 '11 at 19:14
Sorry, I was looking at the docs... from the beamer.cls file, I find this: \ProvidesClassRCS $Header: /home/vedranm/bitbucket/beamer/base/beamer.cls,v a6b1a8434d30 2010/06/21 09:34:49 rivanvx$ –  André Dec 14 '11 at 19:19
What I could do with is the version according to the documentation. Try texdoc beamer: the first page should have a line reading 'User Guide for version 3. x ', where the x is what is what I'm after. –  Joseph Wright Dec 14 '11 at 19:22
Guide for version 3.10 –  André Dec 14 '11 at 19:29

This was a bug which existed in beamer up to version 3.10. It is fixed in the current release (3.12), which for TeX Live can be installed using

tlmgr update beamer


at the command line. You may need sudo/Administrator privileges depending on how TeX Live was installed.

Specifying a default overlay specification for itemize doesn't work with beamerarticle here, however it compiles both in presentation and in article mode if you specify it to \item in your test.tex file which you input:

\begin{itemize}
\item<+-> First
\item<+-> Second
\end{itemize}


It seems to be a bug, see comp.text.tex, so you could check if it's fixed in a newer beamer version and you don't need this workaround if you update.
