[NTG-context] Metapost inclusion does not work

30 Mar 2010

      Hi,

the following example just prints »Hello World!«, without the square.
What's wrong?

\startuseMPgraphic{test}
fill fullsquare scaled 5cm;
\stopuseMPgraphic

\starttext
Hello World!
\useMPgraphic{test}
\stoptext

ConTeXt  ver: 2010.03.20 22:59 MKIV
this is luatex, version beta-0.50.0-2009122419
BTW: The same with luatex 0.52

Thanks in advance.
