multiple columns inside \framed

["Mojca Miklavec" <mojca.miklavec.lists@gmail.com>]

Hello,

I would like to typeset two columns of names inside one frame
(centered horizontally). \startcolumns inside \framed doesn't work; is
there any simple alternative? (Otherwise I'll manually split the
content into two subframes.)

I would appreciate any hints,
    Mojca


\def\student#1#2{{#1 \sc#2}\par}

% room number, number of students, students
\def\room#1#2#3{#1:
	\framed[width=4.4cm,height=2cm]{%
		\ifnum#2<4 #3\else
		\startcolumns[n=2,distance=0pt]#3\stopcolumns
		\fi
	}\par
}


\starttext

\room{1}{2}{%
	\student{Abc}{Def}
	\student{Abc}{Def}
}
\room{2}{5}{%
	\student{Abc}{Def}
	\student{Abc}{Def}
	\student{Abc}{Def}
	\student{Abc}{Def}
	\student{Abc}{Def}
}

\stoptext
