Beamer bookmarks with allowframbreaks

Question

Consider the following MWE which uses this answer to generate a bookmark for each frame:

\documentclass{beamer}

\usepackage{etoolbox}
\usepackage{lmodern}
\usepackage{lipsum}

\usepackage{bookmark}
\makeatletter
\apptocmd{\beamer@@frametitle}{%
  \only<1>{\bookmark[page=\the\c@page,level=3]{#1}}}%
\makeatother

\begin{document}
\begin{frame}
  \frametitle{Foo}
\end{frame}
\begin{frame}[allowframebreaks]
  \frametitle{Baz}
  \lipsum
\end{frame}
\end{document}

When allowframebreaks option is given this means that a bookmark is generated for each of the new frames created by the mentioned option. I want the bookmarks of these "continuation" frames to either have the proper frametitle (i.e "Baz II" rather than just "Baz") or just to generate a bookmark for the first frame and not for those created by the allowframebreak option.

Insert countinuation count in bookmark

The basic idea behind this approach is to check if the \insertcontinuationcount is greater than 0. In this case the continuation count is added to the bookmark.

\documentclass{beamer}

\usepackage{etoolbox}
\usepackage{lmodern}
\usepackage{lipsum}

\usepackage{bookmark}
\makeatletter
\apptocmd{\beamer@@frametitle}{%
    \only<1>{\bookmark[page=\the\c@page,level=3]{#1 \expandafter\ifnum\insertcontinuationcount>0\relax\insertcontinuationcount\fi}}}%
\makeatother

\begin{document}
    \begin{frame}
        \frametitle{Foo}
    \end{frame}
    \begin{frame}[allowframebreaks]
        \frametitle{Baz}
        \lipsum
    \end{frame}
\end{document}

Only bookmarks for first frame

This approach is very similar to the one above. But now, a bookmark is only added if the \insertcontinuationcount is smaller than 2, because it is 0 for "normal" frames or 1 for the first frame of a continuation.

\documentclass{beamer}

\usepackage{etoolbox}
\usepackage{lmodern}
\usepackage{lipsum}

\usepackage{bookmark}
\makeatletter
\apptocmd{\beamer@@frametitle}{%
    \only<1>{\expandafter\ifnum\insertcontinuationcount<2\relax\bookmark[page=\the\c@page,level=3]{#1}\fi}}%
\makeatother

\begin{document}
    \begin{frame}
        \frametitle{Foo}
    \end{frame}
    \begin{frame}[allowframebreaks]
        \frametitle{Baz}
        \lipsum
    \end{frame}
\end{document}

Excellent! Thank! Do you know how to achieve the other possibility of avoiding bookmarks for "continuation frames"? – petobens Sep 25 '14 at 16:50
Also when there are no continuation frames is it possible to avoid numbering it as Foo 0? And just name the bookmark as Foo. – petobens Sep 25 '14 at 16:57
@petobens: see my edited answer to adress your two questions – samcarter_is_at_topanswers.xyz Sep 25 '14 at 17:15
@petobens: does this solve your problem? – samcarter_is_at_topanswers.xyz Sep 25 '14 at 17:37
I've recently noticed two minor problems with your solution: i) if a give the allowframebreaks options but the resulting frame has no continuation frames then the bookmark for that frame still shows Foo I rather than just Foo ii) if I use the option \setbeamertemplate{frametitle continuation}[from second][\insertcontinuationcountroman] the first frame in the bookmarks shows Foo I whereas in the text it is actually Foo and then the second one Foo II. Do you want me to open a another question? – petobens Sep 26 '14 at 19:29
@petobens: concerning your first problem i) The same applies for the frametitle. I don't think this is easily solvable. Perhapse it would be best to open a new question – samcarter_is_at_topanswers.xyz Sep 29 '14 at 14:26

@petobens: concerning ii) If you would like the Foo I to be unnumbered, simply change the >0 to a >1. – samcarter_is_at_topanswers.xyz Sep 29 '14 at 14:34
Great changing to >1 fixes i) and ii)!!! – petobens Sep 29 '14 at 14:41
