"Itemize" error while compiling examples

[Carlos Herrera]

  Hello everyone,

   First of all, thanks for creating this package! It has been very useful in the past.

   A year ago, I used and edited the code provided in example 03 (ZH theme) to create a poster for a conference. Everything worked perfectly. Now I'm trying to create a new one, but when I compile the version that worked a year ago, it gives me an error. I went back to the original example, and I get the same error (and in every example, actually, not just that particular theme). This is the error:

! Undefined control sequence.

<argument> .../enumerate \beameritemnestingprefix

body end

l.154 \end{frame}

The control sequence at the end of the top line

of your error message was never \def'ed. If you have

misspelled it (e.g., `\hobx'), type `I' and the correct

spelling (e.g., `I\hbox'). Otherwise just continue,

and I'll forget about whatever was undefined.

The problem is the "itemize" environment. If I comment all the itemize blocks, it compiles correctly, without errors. But I'd like to include itemize in some sections of my poster. However, I haven't found the way to fix this.

I must say that "itemize" currently works well with common beamer slide presentations and also documents. The problem is just in this package. I'm using a Linux machine with the "texlive-full" package installed. The only difference between last year and now is just the "texlive-full" package version (unfortunately, I don't remember last year's version).

I'd appreciate any suggestions and help to keep using this great tool.

Thanks,

Carlos

Hello Carlos,

I'm having a similar problem, using Windows and MikTeX. It seems that beamerposter loads the paralist package and there is probably a general conflict between beamer and paralist (like here: https://tex.stackexchange.com/questions/80103/why-when-i-add-package-paralist-into-my-beamer-presentation-enumerate-stops-wor).

For my poster I'm going to use the following quick fix:

1. In beamerposter.sty I deleted "\RequirePackage{paralist}".
2. At the end of beamerposter.sty I deleted everything starting from "\edef\indentionLevelValuei{4}" up to the end of the file (as far as I understand it, these are indentation settings for itemize environments – reyling on paralist).
3. In poster.tex I added "\setlength{\leftmargini}{2em}
   \setlength{\leftmarginii}{1.1em}" right after "\begin{document}" to change the indentation without the paralist package.

However, it would be good to find a general and robust solution. If I notice anything else, I'll post it here again.

Best,
Jiří
