letter module: Argument of \dodoubletestempty has an extra }

[Peter Münster]

Hello,

Here a minimal test file, to reproduce the problem with latest MKII:

% engine=pdftex
\usemodule[letter]
\starttext
\startletter
\subject{Test}
hello
\stopletter
\stoptext

Cheers, Peter

Hi Peter,

the message you get is a side effect of the buffer code for mkii,
although i have a fix for the context code it won't be applied because
unwanted side effects can't be be guaranteed.

As you should have noticed your example worked in a older release
where i used a different method to store the letter content which
was changed due to some limitations (e.g. \startlines is not possible).

You can force the old processing method with \setupletterstyle 
[method=store].

Other solutions are to add \relay after \startletter because this stops
contexts optional argument grabber or to leave a blank line after  
\startletter.

Wolfgang
