[NTG-context] Some extra empty pages, why? And how to get an initial blank page with page number 0?

13 Mar 2005

      Fro my environment:
...
%\setuppapersize[B5][B4,landscape]
\setuppapersize[B5][B5]
\setupindenting[small]
\setuplayout[location=doublesided]
%\setuparranging[2SIDE]
\setuppagenumbering[alternative=doublesided]
%
\usemodule[lettri]
\def\ClearChapterQuote{\def\ChapterQuote{}}
\ClearChapterQuote
\newcommand{\ChQuoteFormat}[1]{\starttext%
        %\raggedright%
        \startalignment[left]%
        \startnarrower[4*left] \noindent{\em #1}%
        \stopnarrower\stopalignment\stoptext\blank}
\setuphead[chapter]
        [page=left,
        before={\ChQuoteFormat{\ChapterQuote}\noheaderandfooterlines%
                \page[right]\blank[2*big]},
        after={\ClearChapterQuote\blank[3*big]}%
                \noheaderandfooterlines]
Without \setuppagenumbering[alternative=doublesided], I get single 
sided layout (even if I have the \setuplayout statement, very 
confusing). If I do add \setuppagenumbering[alternative=doublesided], I 
get the following:

1. Title page
2. Empty
3. Page with only a page numer 1 at the top
4. empty
5. Page with Contents 'chapter'
6. Page with quote
7. First page of chapter

Except for pages 3 and 4 that is how I want it. Why are these pages 
there? They are not there if 
\setuppagenumbering[alternative=doublesided] is left out.

My product file looks like this:
...
\startproduct prd_book
\project project_teoada
\starttext
\start
\startstandardmakeup \ss
\hairline \start
\switchtobodyfont[20pt]\bf
\leftaligned{TEOADA}%
\stop \hairline \blank[line]\rightaligned{Gerben Wierda}%
\blank[10cm]\start\leftskip=10cm\hairline\stop
\rightaligned{2005}%
\stopstandardmakeup
\stop
\startfrontmatter
        \completecontent
        \component c_guide
\stopfrontmatter
        \component c_ch1
        \component c_ch2
        \component c_ch3
\startappendices
       \component c_app1
\stopappendices
\stoptext
\stopproduct
I have been trying a lot of permutations but so far without luck.

Secondly, when I turn on 2xB5 on one B4 landscape and 2SIDE 
arrangement, I would like to have an initial blank page (with page 
number 0) so I can have my 2SIDE look just like a book would look. I 
have tried to get one with the \page command in various places and with 
various setups, but so far without *any* effect.

I have been using the manual, the wiki and any documentation I have 
been able to find. So far no luck.

Thanks,

G
