Metapost graphics in separate file, help needed

Metapost graphics in separate file, help needed

[Christian]

Dear List,

I am experiencing a strange problem. I have a project, essentially with the following structure (desperate attempt to keep track of my stuff):

mainfile.mkiv:
% BOF
...lots of setups and settings...
\starttext
\input metapostgraphics.mkiv
\input chapter1.mkiv
\input chapter2.mkiv
\input chapter3.mkiv
\stoptext
% EOF

I generate the PDF with 'context mainfile.mkiv'
So far for the structure. Now my problem:
metapostgraphics.mkiv contains several (4) metapost graphics with \startuseMPgraphics{nameX} ... \stopuseMPgraphics.
In chapter2.mkiv I want to use them with \useMPgraphics{nameX}.
It worked well until today, when I added a fifth graphic. Then I suddenly get a frame with 'undefined' inside instead of the picture.
I tried everything, checked for typos, tried different names, double checked the MP-code etc. but to no avail.

It only works if I put the exact same MP-code between \startMPcode \stopMPcode directly in the chapter2.mkiv

What is wrong here? Am I missing something? Did I get the input mechanism all wrong?

What happens if you make a simple file with the 4 \useMPgraphics in it 
.. does that one process? Maybe there is a problem with the graphics in 
the sense that you cannto run them all in a row.

You can also try adding

begingroup;
....
endgroup;

inside each MP figure. I always wished that this was the default 
behaviour.

Re: Metapost graphics in separate file, help needed

[Christian]

Thanks for the suggestions so far. I' currently testing Hans' idea and it seems to be a problem with caching.

The simple file I made where I just use each graphic runs into an error, but the corresponding code (undefined control sequence '\sb') is definitely not in the current source file of the graphics.

How do I clear the cache to force recalculation of the MP-graphics?

Actually, last week I was tempted to do that but I cannot oversee the 
consequences. It is probably harmless. The interesting thing is that 
beginfig/endfig have grouping but somehow it does not work out well.

Oh boy. This is embarrassing!

Turns out the file that was open in notepad++ was not the one in the path of my project, but had the exact same name. 
And I was editing this sucker  instead of the real file. I guess I should reload my files during sessions.

<insert double face-palm here>
Problem solved, it's sitting right in front of the screen and is banging his head hard against the wall now.

I'm truly sorry that I have wasted your time.

fyi: There is no cache in mkiv as mp is run internally, which is why it 
is so fast (and in mkii caching is clever enough to determine a change).
