Thanks a lot, Wolfgang
just now I was posting a solution of mine,
but yours is more elegant and concise.
Best regards,
Massi
PS: here's my solution (but I'll use yours):
\definemarking[headertitle]
\setupheadertexts[]
\setupheadertexts[\setups{oddpages}][][][\setups{evenpages}]
\startsetups[evenpages]
\pagenumber
\emspace
\getmarking[headertitle][top]
\hfill
\stopsetups
\startsetups[oddpages]
\hfill
\getmarking[headertitle][top]
\emspace
\pagenumber
\stopsetups
\starttext
\startchapter[title=Trial chapter]
\marking[headertitle]{\space}
\marking[headertitle]{Trial chapter}
\dorecurse{11}{\input knuth\par}
\stopchapter
\stoptext
