Hi,
typefaces with a missing font for math produce an error when it’s applied after
\starttext
which is common when the project structure is used where environment files are
loaded
after \startproduct or \startcomponent.
Minimal example:
\starttext
\definetypeface[test][rm][serif][pagella] [default]
%\definetypeface[test][mm][math] [palatino][default]
\setupbodyfont[test]
\input knuth
\stoptext
After playing a bit with possible ways out of this, I decided to stick to
\def\font_helpers_preset_math_family_indeed#fam#familytag%
{\expandafter\ifx\csname\??fontinstanceclass\fontclass-\fontbody-\s!mm-#familytag-\fontsize-1\endcsname\relax
\writestatus{fonts}{math: unset for global bodyfont
\fontclass\space at \fontbody}%
\else
\scriptscriptfont#fam\csname\??fontinstanceclass\fontclass-\fontbody-\s!mm-#familytag-\fontsize-3\endcsname
\scriptfont
#fam\csname\??fontinstanceclass\fontclass-\fontbody-\s!mm-#familytag-\fontsize-2\endcsname
\textfont
#fam\csname\??fontinstanceclass\fontclass-\fontbody-\s!mm-#familytag-\fontsize-1\endcsname
\fi}
After all, it's an error not to define math for a 'global' bodyfont.
