[Tex/LaTex] Latex: \footnote command not working in solution environment of exam package

Question

I'm using exam package, I would like to add a footnote to a solution: it displays the mark but not the note text. In question environment it is all right.

\documentclass[12pt, answers]{exam}
%\documentclass[12pt]{exam}
\usepackage[english, italian]{babel}
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage[usenames,dvipsnames]{color}
\usepackage[utf8x]{inputenc}
\usepackage{verbatim}
\usepackage{minted}
\usepackage{footnote}
\renewcommand{\solutiontitle}{\noindent\textbf{Risposta:}\enspace}

\newcommand{\col}[1]{{\color[rgb]{0.094,0.235,0.36}{#1}}}
\newcommand{\myt}[1]{\textbf{\col{#1}}}
\newcommand{\myhdr}[4]{
\pagestyle{headandfoot}
\firstpageheader{\myt{#1}}{\Huge\myt{#2}}{\myt{#3}}
\runningheader{\myt{#1}}{\Huge\myt{#2}}{\myt{#3}}
\firstpagefooter{}{\myt{#2}}{\myt{#4}}
\runningfooter{}{\myt{#2}}{\myt{#4}}
\runningfootrule
}


%\myhdr{3A - INT}{Domande da un minuto}{Sistemi}{Pag. \thepage\ - \numpages}
\checkboxchar{$\Box$}

\question
In quanti livelli viene, di fatto, divisa la gerarchia della rete dal momento in cui aggiungo le sottoreti?
    \begin{solution}Tre: rete, sottorete e host\end{solution}
\question
Che cosa viene facilitato dalla creazione di un ulteriore livello nella gerarchia di rete?
    \begin{solution}La creazione dei sottogruppi nella rete IP che ne deriva facilita la velocizzazione di trasmissione dei pacchetti e la minimizzazione del traffico locale\footnote{8.0.1.1: Introducing an additional level to the hierarchy creates additional sub-groups within an IP network that facilitates faster packet delivery and added filtration, by helping to minimize ‘local’ traffic.}\end{solution}
\end{questions}
\end{document}

I would like to have it working even with my footer on, though commented in this example.

Answer 1

You can use the footnote pacakge to obtain footnotes from within the exam class:

Code:

\documentclass[12pt, answers]{exam}

\usepackage{footnote}
\makesavenoteenv{solution}

\begin{document}
\begin{questions}

\question
Some question
\begin{solution} 
    Text\footnote{Some footnote} 
\end{solution}

\end{questions}
