Hello Hans,
Finally it took me less time. Here is it:
\usemodule[pre-stepwise]
\def\startC{%
\bgroup
\whitespace
\obeylines
\activatespacehandler{yes}%
\strut}
\def\stopC{\egroup}
\setupinteraction[state=start]
\setuppapersize[S6][S6]
\setupwhitespace[big]
\starttext
\startcolumns\placelist[chapter]\stopcolumns
\startC
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
bla
\stopC
\stoptext
the problem, is that the catcodes are changes in the main vector and
that influences code handled in the output routine
there is no easy way around this (apart from not switching catcodes)
so, after figuring out that in this case the prooblem is in delayed
expansion of
\definereference [CheckStepper] [JS(CheckStepper{\StepCounter})]
i decided to add a push/popper, which works like this
\def\startC
{\bgroup
\pushcatcodes
\whitespace
\obeylines
\activatespacehandler{yes}%
\strut}
\def\stopC
{\popcatcodes
\egroup}
of course this is only needed when changes to catcodes are made that
bleed into the page builder (happens seldom)
