pagination problem with \startitemize[columns]

pagination problem with \startitemize[columns]

[Nikolai Weibull]

I sent a response to an earlier thread about this, but I don't know if
it got through (my mail was down later that day).  Anyway, here's an
example of something that gets messed up.  Text following the itemize
doesn't get paginated properly.  Having a new chapter after it seems to
fix it from there on, though.

\starttext

\chapter{One}

\dorecurse{7}{\input zapf \par\relax}

\startitemize[columns,four]
\dorecurse{12}{\nop \type{[:alnum:]}}
\stopitemize

\dorecurse{7}{\input zapf \par\relax}

\stoptext

This fails for \startitemize[columns] as well.  It seems that the problem
arises when the itemize is pushed onto the second page.  Remove the
first \dorecurse{7}{\input ...} and it works fine...

Here's an example where the following chapter will be typeset correctly:

\starttext

\chapter{One}

\dorecurse{7}{\input zapf \par\relax}

\startitemize[columns,four]
\dorecurse{12}{\nop \type{[:alnum:]}}
\stopitemize

\dorecurse{7}{\input zapf \par\relax}

\chapter{Two}

\dorecurse{7}{\input zapf \par\relax}

\stoptext

Hi Nicolai,

I am not shure that the second example works. Also there I get the same 
problem as in example one. The pagebreak-problem remains als if you 
withdraw \nop and replace it with \item

I use currently version:

ConTeXt  ver: 2004.3.19  fmt: 2004.6.6
This is pdfeTeXk, Version 3.141592-1.11a-2.1 (Web2c 7.5.2) 
(format=cont-en 2004.6.6)  12 JUN 2004 15:00

Hans, what is the meaning of the k behind PdfTeX?

i posted a fix for that:

\def\endmulticolumns
  {%\par
   \vskip\lineheight\vskip-\lineheight % take footnotes into account
   \dontshowcomposition
   \doflushcolumnfloat  % added recently
  %\doflushcolumnfloats % no, since it results in wrong top floats
   \flushnotes          % before start of columns
   \par
   \ifbalancecolumns
     \global\output{\continuousmulticolumnsout}%
     \goodbreak
     \global\output{\balancedmulticolumnsout}%
   \else
     \goodbreak
   \fi
   \eject               % the prevdepth is important, try e.g. toclist in
   \prevdepth\zeropoint % columns before some noncolumned text text
   \global\output\singlecolumnout
   \global\output{\the\mainoutput}% % % % % todo
   \ifvoid\precolumnbox\else
     \unvbox\precolumnbox
   \fi
   \global\precolumnboxheight\zeropoint
   \endgroup % here
   \nofcolumns\plusone
   \setvsize % the outer one!
   \synchronizeoutput % new may 2004 / we need to: \pagegoal\vsize
   \checkendcolumnfootnotes
   \dosomebreak\allowbreak
   \restoresavedfloats}

this should go into cont=new.tex
