getbuffer now fails

getbuffer now fails

[Hans van der Meer]

I had this code working (it was in an article I submitted for NTG-MAPS  
a while ago, july 2007). Now this same code gives an error on getbuffer.
What happened to getbuffer? Is it possible a \fi has disappeared in  
the getbuffer code between now and last july? Is there a quick patch  
because now I get stuck on work that has to be finished.

The error message from TeX:
! Incomplete \ifx; all text was ignored after line 6.
<inserted text>
                 \fi
<to be read again>
                    \relax
\dodoreadfile ...d \relax \fi \dodoreadfileindeed
                                                   \relax \the  
\everyafterrea...

\mkdobuffer #1->\beginrestorecatcodes #1
                                         \endrestorecatcodes
\dodobuffer ...dcsname \else #2\fi }\mkdobuffer #1
                                                   \popmacro  
\currentbuffer
\dodogetbuffer ...}\dobuffer {16}{#2}\mkgetbuffer
                                                   \getvalue {\??bu  
#1\c!after }
...
l.111 \question[number=1][buffer]{\getbuffer}

The relevant part of the code, not working is the call to \@exmbuffer:
	...
	\doifelse{#2}{\v!buffer}%
		{\def\filename{buffer}\def\thefile{#3}\let\@@exminput\@exmbuffer}%
		{.....}%
	\@@exminput\thefile
	\endgroup}
% reading the file better outside the doif
\def\@exminput#1{\input#1\relax}
\def\@exmbuffer#1{#1}

Help is appreciated.

Hi Hans,

Could you send us the example and the version of your ConTeXt
installation. It would be also interesting is you use MkII or MkIV to
process your files.
