Hi Hans,

The example with clearboxes's crash:

\setupoutput[pdftex]

\starttext
\startuseMPgraphic{my_uml_figure}
input metauml;

Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B);
\stopuseMPgraphic

\placefigure[here]{none}{\useMPgraphic{my_uml_figure}}

\stoptext

The resulting pdf looks good... strange...

I use teTeX on debian + metapost 0.901
renaud@rescue:/usr/share/texmf-tetex/metapost/base$ grep clearboxes *
boxes.mp:  expandafter def expandafter clearboxes expandafter =
boxes.mp:    clearboxes cl($);
boxes.mp:  & "boxjoin();save pic_,sproc_,pproc_;def clearboxes=enddef;";
boxes.mp:extra_endfig := extra_endfig & "clearboxes;";

Now, I have solved my problem with this (horrible!?) hack:

\startuseMPgraphic{my_uml_figure}
input metauml;
beginfig(1);
Class.A("Point")
       ("+x: int",
        "+y: int") ();

Class.B("Circle")
       ("radius: int")
       ("+getRadius(): int",
        "+setRadius(r: int):void");

topToBottom(45)(A, B);

drawObjects(A, B);

clink(aggregationUni)(A, B);
endfig;
\stopuseMPgraphic

I don't want to put "input metauml;" within MPinclusions because for my
PhD thesis, I have a lot of MPgraphic (without MetaUML) and:
1. I don't want to load metauml for each metapost run
2. I use MetaObj... (MetaUML and MetaObj interfere to each other)

Cheers,

Renaud
