Glossary entries error

Question

I'm trying to introduce some entries in the glossary with \usepackage{glossaries} and I don't know how to introduce symbols with arrows, like vector fields. If I don't use name=$\overrightarrow{E}$, works fine but I need to put the right symbol.

this is my entry:

\newglossaryentry{symb:efield}{
name=$\overrightarrow{E}$,
description={Electric Field},
sort=symbolefield, type=symbolslist
}

and I have at least 4 error related to that:

Illegal parameter number in definition of \glo@symb:efield@text.
Illegal parameter number in definition of \glo@symb:efield@plural.
Illegal parameter number in definition of \glo@symb:efield@first.
Illegal parameter number in definition of \glo@symb:efield@firstpl.

Why is that?

Try this code.

\documentclass{article}
\usepackage{glossaries}
\newglossary*{symbolslist}{Symbols list}
\newcommand{\field}[1]{\protect\overrightarrow{#1}}  % use \protect
\newglossaryentry{symb:efield}{%
    type=symbolslist,
    name={\ensuremath{\field{E}}},
    description={Electric Field},
    sort=symbolefield, 
}
\makeglossaries
\begin{document}
overrightarrow: $\field{AB}$
\medskip
\gls{symb:efield}
\printglossary[type=symbolslist]
\end{document}

Must use use \protect because overrightarrow is not robust.

Or use \DeclareRobustCommand{\field}[1]{\overrightarrow{#1}} as alternative.
