(Sorry, always me)
I have such a structure
\startproduct prd_tSCIRMA\project project_scMaterials
\component licence\component prima
{\switchtobodyfont[20pt] Sommario}\blank\placecontent\component
c_00_introduzione\component c_01_scGrado0 \component c_03_oggetti
% etc
\stopproduct
Everything works perfectly if I arrange one page for sheet, e.g.
\setuppapersize[A5][A5]
or
\setuppapersize[A5][A4, landscape]
If have more pages for sheet,
\setuppapersize[A5][A4, landscape]
\setuparranging[2*2]
there's no table of content in the pdf.
imposition.
