Re: Solution: METAPOST textext() eats my \pars. Was: Setting vertical spacing of lines inside a \framed[align=]

On a hunch, I found a solution. I added \\ instead of \par at the end and goit exactly what I wanted.

\enabletrackers[context.trace]
\starttext

%\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}}

\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}");
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)\\}}") shifted (200,0));
\stopMPpage


\stoptext
