Well, I start from the beginning with odd/even layout setting, and the following does not work. The behaviour I see is that only the odd setting is used. What is wrong in there?
\definelayout[odd] [width=middle, backspace=7cm, cutspace=5cm]
\definelayout[even] [backspace=8cm, cutspace=2cm, width=middle]
\setuplayout
%\showlayout
\starttext \dorecurse{4}{ \section{Hello} \input knuth \endgraf \subsection{Sub Hello} \input tufte \endgraf} \stoptext
Hallo! This doesn't work here, too! The wiki said it should work. So, maybe there ist something broken in the meantime. In 'page-lay.tex' I found something with \setuplayout[odd][state=stop] \setuplayout[even][state=stop] so a.) Not alone \definelayout but also \setuplayout should work with odd|even. b.) Because there is something to stop here, there may be some need to start it? Btw. \definelayout[1][] doesn't work too. Wolfgang
