Thank you, that works. (Can’t put in the images to show, as this gets my 
message over 100k)

But it turns out, I have an additional problem because I am doing this inside a 
textext() from METAPOST and that seems to strip the \pars again. Tracking 
ConTeXt:

cld > tex > f : 8 : picture pic; x:=33.000; y:=53.000; w:=133.000; 
h:=53.000;pic := ApplicationComponentLogo( w, h, (0.686,1.000,1.000), 0.200, 
1.000, (0.000,0.000,0.000), 1.000, 0.700, (0.000,0.000,0.000), 1.000, 
"\framed[align=flushright,frame=on,offset=none,width=106.400bp]{\colored[r=0.000,
 g=0.000, b=0.000]{\switchtobodyfont[11.0pt]\setupinterlinespace[11.5pt] \rm 
[My]\\Application\\(Component)\par}}\par") shifted (x, -y); draw pic;path 
AllNodeIds_idIC;  AllNodeIds_idIC := pathpart pic; pair AllNodeCenters_idIC; 
AllNodeCenters_idIC := center pic;

which looks OK (this is lmtx passing the string to ConTeXt using the lua 
context() call). The \pars are still there.

Then later, when METAPOST is at it and that same string is used to put into 
textext(), it results in:

cld > tex > w : - : \MPLIBsetNtextX{3}{\framed 
[align=flushright,frame=on,offset=none,width=106.400bp]{\colored [r=0.000, 
g=0.000, b=0.000]{\switchtobodyfont [11.0pt]\setupinterlinespace [11.5pt] \rm 
[My]\\Application\\(Component)}}}


Minimal example:

\enabletrackers[context.trace]
\starttext

% Works OK:
\framed[align=flushright,frame=on,offset=none,width=106.400bp]{\colored[r=0.000,
 g=0.000,
b=0.000]{\switchtobodyfont[11.0pt]\setupinterlinespace[11.5pt] \rm 
[My]\\Application\\(Component)\par}}

% Doesn’t work:
\startMPpage[instance=doublefun]
draw 
textext("\framed[align=flushright,frame=on,offset=none,width=106.400bp]{\colored[r=0.000,
 g=0.000, b=0.000]{\switchtobodyfont[11.0pt]\setupinterlinespace[11.5pt] \rm 
[My]\\Application\\(Component)\par}}\par");
\stopMPpage


\stoptext

So, now I’m looking for a way to prevent textext() to eat my \pars

Re: [NTG-context] metapost textext?

[Hans van der Meer]

I have another piece of information on my previous posting.
When I take the mpgraph mp-input for metapost produced by the ConTeXt  
run I see:


(1) running system(mpost  -progname=mpost -mem=metafun standalone2- 
mpgraph)...executed. as the log shows gives the wrong metafont  
output. I also ran mpost with those parameters standalone on that mp- 
file and got the same bad result.


(2) running texexec --mptex on the file gives the correct result.

Would this help locating the problem?
My mpost is according to mpout.log This is MetaPost, Version 0.901  
(Web2C 7.5.3) (mem=mpost 2005.11.12).


yours sincerely,
dr. H. van der Meer

Runs without problems here as well. The most likely cause of problems
in this subsystem nowadays is a
  format was written by (pdf)(e)tex
error message from a (pdf)(e)tex executable. Unfortunately, I also
find it hard to trace this stuff. It may help to run the example
in an isolated directory and zipmail everything in the directory
afterwards. I can at least have a look, but cannot give guarantees.
