Large number of authors and affiliations does not show correctly

[codingS3b]

In my draft, 25 coauthors and 23 affiliations are involved which caused the template to behave strangely: in the pdf, a first, empty page is generated, followed by a full titlepage with author names and affiliations typed straight to the bottom of the page (without respecting margins). The rest of the authors and affiliations disappears instead of showing up on a second page.

I hope this can be fixed before the submission deadline arises.

Can you provide a MWE? We are relying on the JMLR / PMLR template meaning we have little leeway to modify the template but we will try our best.

[codingS3b]

Of course. This reproduces the problem on my system:

\documentclass{midl} % Include author names
%\documentclass[anon]{midl} % Anonymized submission

% The following packages will be automatically loaded:
% jmlr, amsmath, amssymb, natbib, graphicx, url, algorithm2e
% ifoddpage, relsize and probably more
% make sure they are installed with your latex distribution

I hope this can be fixed before the submission deadline arises.

Bear in mind that this year, the review process is double blind, so this will be a problem only for the final version. This means we have a bit more time to fix that.

[tvercaut]

An ugly hack for now:

%\begin{comment}
\makeatletter
% hack the footer of the title page as it doesn't seem to automatically use the et al. version when spanning acros multiple pages
\renewcommand*{\@titlefoot}{\scriptsize\copyright\space\@jmlryear
    \space \@firstauthor\space \emph{et al}.\hfill
    \@reprint
  }
\makeatother
%\end{comment}

% \begin{comment}
\makeatletter
% remove the vbox in @jmlrmaketitle which prevents the text to be split across several pages
\renewcommand{\@jmlrmaketitle}{
  % specify the page style in case it spans over several pages. Not sure why this is needed
  \thispagestyle{jmlrtps}%
  % define a new label for the first page as otherwise it starts from 2 in the header
  \label{jmlrstartnew}%
  % hack the spacing to mimick what happens with a vbox
  \null\vspace{-\parindent}\vspace{-2pt}{
  \hsize\textwidth
  \linewidth\hsize
 \jmlrpretitle
  {%
    \def\titletag##1{##1}%
    \@title
  }%
 \jmlrposttitle
 \jmlrpreauthor \@author \jmlrpostauthor
}
% hack the spacing to mimick what happens with a vbox
\vspace{2pt}
}
\makeatother
%\end{comment}

%\begin{comment}
\makeatletter
% hack the footer to use the new counter
\renewcommand*\@jmlrpages{\pageref{jmlrstartnew}--\pageref{jmlrend}}
\makeatother
%\end{comment}

This can be put in a file such as many-authors-hack.tex and this file can then be used in your own tex sources using \input{many-authors-hack}

[codingS3b]

Thanks, this seems to work for me :) Should I close the issue or leave it open until a less hacky solution exists?

[tvercaut]

Let's leave it open for now. I created a bug report upstream: https://www.dickimaw-books.com/bugtracker.php?action=view&key=141
