How to get correct glossary links with frontmatter pages?

Question

I'm using the glossaries and hyperref packages, and my document has 10 or so pages of frontmatter, in roman numerals.

All the links in the glossary have the correct page numbers, but when you click them they go to the wrong page. They go to the side of that number, but they fail to include the frontmatter in the count, so are offset,

E.g. an acronym used on page 20, in a document with 10 pages of frontmatter, will link to the side numbered 10 in the pdf.

How can I fix this? I'm using MacTeX-2010.

Edit:

\documentclass[twoside]{book}

\title{A LaTeX Article}
\author{Your name here}
\date{2011-06-27}

\usepackage{hyperref}
\usepackage[acronym]{glossaries}
\makeglossaries

\begin{document}
    \newacronym{www}{WWW}{World Wide Web}
    \newacronym{http}{HTTP}{HyperText Transfer Protocol}
    \frontmatter

    \maketitle

    \tableofcontents

    \printglossaries

    \mainmatter

    \chapter{Introduction}
    The \gls{www} is big.

    \chapter{Next}
    The \gls{www} works over \gls{http}.
\end{document}

Answer 1

In creating the example above, I found it worked.

In my situation I'm using a custom style, which had set the hypertexnames=false option to the hyperref package. I replaced that with plainpages=false and pdfpagelabels which fixed it.
