Hi,

I've written the following test file:

======================
\setupcolors[state=start]
\setuppagenumbering[state=stop]
\setupinteraction  [state=start]

\starttext

\MPdrawingdonetrue

\startMPdrawing
draw (0,0)--(2cm,2cm);
\stopMPdrawing
\definesymbol[aa][\getMPdrawing]

\startMPdrawing
draw (2cm,2cm)--(2cm,0);
\stopMPdrawing

\definesymbol[bb][\getMPdrawing]

\startMPdrawing
draw (0,0)--(2cm,0);
\stopMPdrawing

\definesymbol[cc][\getMPdrawing]

\definefieldstack[somemap][aa,bb,cc][height=fit,width=fit,frame=on]


\fieldstack[somemap]
\goto{here} [JS(Walk_Field{somemap})]

\stoptext
======================

It seems that the fieldstack does not work. Is there anything wrong?
