Beamer: \againframe inside other frame

Question

I'd like to repeat a certain state of a frame in beamer. Say like this:

\frame[label=A]{
    \begin{itemize}
        \item<1> foo
        \item<2> bar
    \end{itemize}
}

\frame{
    \begin{itemize}
        \item<1> fooagain
        \item<3> baragain
    \end{itemize}
    \only<2>\againframe<1>{A}
    \only<4>\againframe<2>{A}
}

However, this would not work as one can only call \againframe outside of other frames.

I would be fine with this constraint however, I don't want a mini frame for each frame I call again (with \againframe).

Do you know a solution for that?

Answer 1

I'm not 100% sure I understand what you want to achieve, but maybe it's this:

\frame<2,4>[label=A]{
    \begin{itemize}
        \item<1> fooagain
        \item<2> foo
        \item<3> baragain
        \item<4> bar
    \end{itemize}
}
\againframe<1-4>{A}

(I think this is also what @gotgenes has in mind.)

Answer 2

I'm not exactly clear on what you would like, but would newcommand suffice?

\newcommand{\twolist}[2]{\begin{itemize}\item #1 \item #2 \end{itemize}}
\begin{document}
\frame{
  \twolist{foo}{bar}
}
\frame{
  \twolist{fooagain}{baragain}
  \twolist{foo}{bar}
}
\end{document}
