My question is closely related to this question, but slightly different, so that @samcarter's answer to that question doesn't help.
I want to combine the allowframebreaks option with the <+-> option but using the standard way to combine options doesn't achieve this. Here's an MWE. The first frame uses allowframebreaks in the standard way, producing two pages. The second frame tries to combine the two options, implements the \pause command but ignores the allowframebreaks option. Reversing the order of the two options generates an error.
\documentclass{beamer}
\begin{document}
\begin{frame}[allowframebreaks]{Title}
This is a test
\pause
This is a test
\newpage
Page 2
\pause
This is a test
\pause
This is a test
\end{frame}
\begin{frame}[<+->,allowframebreaks]{Title}
This is a test
\pause
This is a test
\newpage
Page 2
\pause
This is a test
\pause
This is a test
\end{frame}
\end{document}
