m-chart spoils second flowchart

m-chart spoils second flowchart

[David Antos]

	Hi all,

using m-chart, I have two flowcharts in a document. The problem is that
lines of the first one are added to the second one, in addition to its own
lines. Compiling each chart separately is absolutely OK. Metaposting
mpgraph.mp obtained from running all together produces the wrong result.
The flowcharts are in two different components, the \setupFLOWcharts is in
the environment, nevertheless placing them in one file doesn't help.
(ConTeXt from TeXlive6.)

The files can be found at
http://www.fi.muni.cz/~xantos/patlib/thesis

The setups from the environment (defs.tex):
%%% FLOW charts
\usemodule[chart]

\setupFLOWcharts
  [nx=3,
   ny=5,
   maxwidth=\textwidth]

The components contain flowchart definition and \placefigure with flowchart
usage. The files are patlib.tex and opatgen.tex, the flowcharts are at the
very ends of the files ;)

What am I doing wrong?

	Thanks for the answer

					D.A.

This problem seems to arise when MP is run BETWEEN TeX runs.
You have to enable \write18, so that TeX cann call MP during the TeX
run.
Most modern TeX distributions support this feature (of course, it opens
a security hole, too, but the tradeoff should not be that big), you just
have to switch it on.

You're right, the problem is that i mostly run realtime so this went 
unnoticed. However, it is a bug since context is supposed to work both ways.

I patched mp-char.tex, i.e. added an additional init def (i really have to 
clean up that module; actually there was a remark there already about the 
need for a namespace).

So, the next release will work ok and i'll send david the patch,
