Subpagenumbers and unwanted last page with MkIV

Subpagenumbers and unwanted last page with MkIV

[Wolfgang Schuster]

Hi,

the following example with subpagenumbers works fine with MkII, but
MkIV produce a extra last page and I try to get rid of this page.

\setupsubpagenumber
  [number=1,
   way=bytext,
   state=start]

\setupheadertexts[\subpagenumber--\numberofsubpages]

\starttext

\dorecurse{8}{\input knuth\par}

\page

\resetsubpagenumber

\dorecurse{8}{\input zapf\par}

\stoptext

Greetings,

Wolfgang

After more than a hour research I found the problem for the extra
page in mkiv with subpagenumbering.

The following lines solve it:

\unprotect

% core-two.mkii

\ifx \immediatesavetwopassdata\undefined
\let\immediatesavetwopassdata\savetwopassdata \fi

% page-num.tex

\def\savenofsubpages
  {\ifsubpaging
     \showmessage\m!layouts6{\newnofsubpages,\the\subpageno}%
     %\savetwopassdata{\s!subpage}{\newnofsubpages}{\the\subpageno}%
     \immediatesavetwopassdata{\s!subpage}{\newnofsubpages}{\the\subpageno}%
   \fi}

\protect

The mkiv definition for \savetwopassdata store the value after the shipout
and not immediately as the mkii version did and this cause another page
in the output to store the information.
