Hi,
Thanks for your attention, Wolfgang: indeed removing
    \analyzecurrentreference
from your example allows mkiv to typeset correctly and obtain the
expected result.

....
yet another sparsely documented feature ... in beta:
% tests/mkiv/pagestate-001.tex
\useMPlibrary[dum]
\setuppagenumbering
  [alternative=doublesided]
% new: \setupreferencing[doublesided=no]
% old: \somewhere{backward}{foreward}[label]
% new:
\someplace{preceding}{backward}{current}{foreward}{following}[label]
% old: \atpage[#label]
% new:
\doifcheckedpagestate{label}{preceding}{backward}{current}{foreward}{following}{otherwise}
\starttext
\dorecurse {20} {
    \placefigure
      [here]
      [fig:#1]
      {}
      {\externalfigure[dummy]}
    \dorecurse {20} {
        ##1: \atpage[fig:##1] /
        \doifcheckedpagestate{fig:##1}
         {preceding}
         {backward}
         {current}
         {foreward}
         {following}
         {otherwise}
    }
}
\stoptext
if okay, then it's something to wikify ... should
\setupreferencing[doublesided=no] be default? (currently yes i.e.
spread aware)
keep in mind that this kind of functionality once it kicks in (is
used) can result in a few more runs to get thing right and that
there's always the danger of oscillation as the text injected is
dependent on the situation
Hans
This looks very promising. When I test it with today's beta, I see that
"current" is set in some iterations, but never shows up in the final
version of the page, so references on the same page always come out as
"backward" or "forward".
well, in the case of 5 alternatives current will only happen when the 
reference is at the *exact* spot as the thing referred to; so, in the 
case of

   text [target] text [reference] text

the target is before the reference on the same page contrary to

   text \hbox to 0pt{[target]}\hbox to 0pt{[reference]} text

of course 'current' seldom happens but it's part of the solution set anyway
...
I would think that the default should match the default for
\setuppagenumbering[alternative=], and perhaps be tied to that.
