Hello Wizards, the next example illustrates the problem with wrong order of content-list items if using balanced columnsets: ----------------------------------------------------------------- \setuplayout[grid=yes,topspace=1cm,bottomspace=1cm,height=middle] \showgrid \definecolumnset[A][n=2,balance=yes] \setupcolumnsetlines[A][1][1][21] \setupcolumnsetlines[A][1][2][21] \definecolumnset[B][n=2,balance=yes] \starttext \startcolumnset[A] \section{Knuth} \dorecurse{2}{\input knuth \endgraf} \stopcolumnset \placeongrid{\hairline} \startcolumnset[B] \section{Zapf} \dorecurse{1}{\input zapf \endgraf} \blank Content: \placecontent[criterium=all] \stopcolumnset \stoptext -------------------------------------------------------------------- Problem is that the second section (Zapf) is inserted to .tui before the first one (Knuth). My observation: on the page where one columnset (A) is closed by \setupcolumnsetlines and the second (B) continues, .tuo contains marks from B firstly. This makes book content unsable in this configuration. Any solutions? I am thinking about: Proper order writting to .tuo or to sort items according to mark number - it is correct (not sure if it is implemented?). Thanks Vit
