page reference to figure fails when figure location is "none"

page reference to figure fails when figure location is "none"

[Sanjoy Mahajan]

Using a recent MkIV beta (2014.03.27), it seems that a page reference to
a figure fails if the figure location is "none."  Here is a minimal
example:

  \starttext

  \input knuth

  \placefigure[none][regularref]{}{\pagereference[workaroundref]
  \externalfigure[cow.pdf]}

  \input knuth

  See \at{page}[workaroundref]  or \at{page}[regularref]

  \stoptext

The log file has

  references      > unknown reference '[][regularref]'

and the .pdf file has

  See page 1 or page ??

That is, the "\at{page}[regularref]" doesn't work.  (But the workaround
reference does work.)

If the figure's location key is changed from "none" to "nonumber" or
just deleted, then the regularref page reference works.

It also works with MkII (with or without "none"), so I am guessing that
it is a bug in MkIV.

more a side effect .. in mkii we store refs independently, in mkiv they 
can also travel with other properties (like lists and here we have no 
list entry

in the next beta this will work ok

\starttext

\placefigure
   [none]
   [regularref-1]
   {}
   {\hbox{\pagereference[workaroundref-1]\externalfigure[cow.pdf]}}

\placefigure
   [here]
   [regularref-2]
   {}
   {\hbox{\pagereference[workaroundref-2]\externalfigure[cow.pdf]}}

See \at{page}[workaroundref-1] or \at{page}[regularref-1]

See \at{page}[workaroundref-2] or \at{page}[regularref-2]

\blank

\placelist[figure][criterium=text]

\stoptext

That make sense.  I will try it out.

I have found a few other buglets with placefigure for which I will make
minimal examples.
