# Why can't I set hyperref's pdfinfo from within a group? (Is it a bug?) [closed]

When I run the following code (using hyperref version 2012/09/27 v6.83g), I do not get any errors or warnings, but the metadata I set using pdfinfo doesn't appear. If I uncomment the \@firstofone line, effectively removing the group, it does.

I could not see any documentation in the manual that states one must be careful to use pdfinfo outside of all groups, so I have a feeling this might be a bug. Due to the grouping issue, I suspect this bug is caused by internal assignments in hyperref being local instead of global. I get a bit lost when reading the hyperref code, so I have so far been unable to determine the cause (and therefore a solution) to this problem.

\documentclass{article}
\usepackage{hyperref}

\makeatletter
%\@firstofone
{
}

\begin{document}
\end{document}


(Of course, in my actual example, I don't know how many levels deep I need to 'escape', and neither do I know any such way to escape! I cannot easily test my assumption about assignment locality as I am not aware of any trick to set a flag or something to make all assignments in a group global even if they were not defined \global, and I expect that may have other unwanted consequences anyway.)

Is anyone able to offer a fix or a workaround?

Oh, and I'm using the pdflatex workflow. –  cyberSingularity Oct 7 '12 at 11:14
If I use Author instead of extrainfo, the setting is respected independently of grouping. The "unknown" key instead is added only if at the outer level. –  egreg Oct 7 '12 at 11:20
Please send bug reports direct to the package author. A question and answer site isn't really the right place for bug reports. –  Martin Scharrer Oct 14 '12 at 7:06
