[Tex/LaTex] Disable beamer frame numbering with framebreaks

beamerpage-numbering

In my beamer presentation, the bibliography frames (which are the last frames) are set not to be included in the numbering. Hence the total number of frames (printed as "current frame number/ total frame number") does not count the bibliography frames. I was using the following code for that:

\documentclass[xcolor={dvipsnames,table},11pt]{beamer}
\setbeamertemplate{footline}{\insertframenumber/\inserttotalframenumber}
\begin{document}
\begin{frame}[noframenumbering]
\begin{thebibliography}{}
\bibitem{} The total frame number is displayed as zero,
\bibitem{} which means the frames are not countered.
\end{thebibliography}
\end{frame}
\end{document}

It was working fine. Then I decided to include framebreaks, using the command:

\begin{frame}[noframenumbering, allowframebreaks]

The frames are broken correctly, but the blibliography frames are now numbered, except the first one. For example, if three bibliography slides are there, the total number gets increased to "x+(3-1)=x+2". What I need is an unchanged total frame number (ie "x+0").

Any suggestion would be helpful. Thanks in advance.

Manual hack:

\documentclass[xcolor={dvipsnames,table},11pt]{beamer}
\setbeamertemplate{footline}{\insertframenumber/\inserttotalframenumber}
\begin{document}
\frame{}

\begin{frame}[allowframebreaks]
\begin{thebibliography}{}
\bibitem{} The total frame number is displayed as zero,
\framebreak
\bibitem{} which means the frames are not countered.
\end{thebibliography}
\end{frame}
\addtocounter{framenumber}{-2}
\end{document}

Or an automatic solution if you can live with all allowframebreak frames to be unnumbered:

\documentclass[xcolor={dvipsnames,table},11pt]{beamer}

\setbeamertemplate{footline}{%
    \ifnum\insertcontinuationcount>0
        \addtocounter{framenumber}{-1}
    \fi
    \insertframenumber/\inserttotalframenumber
}

\begin{document}
\frame{}

\begin{frame}[allowframebreaks]
\begin{thebibliography}{}
\bibitem{} The total frame number is displayed as zero,
\framebreak
\bibitem{} which means the frames are not countered.
\end{thebibliography}
\end{frame}

\end{document}

[Tex/LaTex] Beamer frame numbering in appendix

I've used the following macros for this purpose:

\newcommand{\backupbegin}{
   \newcounter{framenumberappendix}
   \setcounter{framenumberappendix}{\value{framenumber}}
}
\newcommand{\backupend}{
   \addtocounter{framenumberappendix}{-\value{framenumber}}
   \addtocounter{framenumber}{\value{framenumberappendix}} 
}

The bonus slides are then put between the two commands:

\appendix
\backupbegin

\frame{\frametitle{One more thing}}

\backupend

This will get you the desired numbering, too.

[Tex/LaTex] Avoid frame numbering in references that span more than one frame in Beamer

I found this thread which is very similar to my problem, even though it is about appendix frames instead of bibliography frames.

Among the answers, this one indicates that the parameter noframenumbering is not inherited by the additional frames added by allowframebreaks and proposes to add the following code to the preamble:

\usepackage{etoolbox}
\makeatletter
\preto{\appendix}{%
  \patchcmd{\beamer@continueautobreak}{\refstepcounter{framenumber}}{}{}{}}
\makeatother

I tried to do something similar for my need (i.e. changing \appendix for \bibliography), but could not succeed. Errors like the following were presented, indicating that perhaps the \bibliography command does not have a similar structure to the \appendix command:

Argument of \bibliography has an extra } ...reak}{\refstepcounter{framenumber}}{}{}{}}

However, I tried this other answer that proposes to handle the frames as backup frames. First, it proposes to add the following macros to the preamble:

\newcommand{\backupbegin}{
   \newcounter{framenumberappendix}
   \setcounter{framenumberappendix}{\value{framenumber}}
}
\newcommand{\backupend}{
   \addtocounter{framenumberappendix}{-\value{framenumber}}
   \addtocounter{framenumber}{\value{framenumberappendix}} 
}

And then it proposes to use those macros to enclose the definition of the frames you do not want to have influence in the frame numbering.

So, I defined my reference frames like this:

\backupbegin
\begin{frame}[plain, allowframebreaks]
    \frametitle{References}
    \bibliographystyle{abbrv}
    {\tiny \bibliography{bibliography}}
\end{frame}
\backupend

And it all worked like a charm! The additional frames no longer are being accounted in the frame numbering. :)

P.S.: If somebody knows how to use the solution for the first answer referred to bibliographies, that would be very useful. It seems to me that that approach "feels" to be more correct.
