picture- and formula-references broken with current beta

[Andreas Harder]

Hi all,

can someone confirm that picture- and formula-references are broken with the current beta. Here is a test file:

\starttext
\placefigure[auto][pic:1]{caption}{\externalfigure[dummy]}
\placeformula[for:1]
\startformula
  a+b
\stopformula

\in{picture}[pic:1]
\in{formula}[for:1]
\stoptext

Greeting
	Andreas

New beta. Can you check again? Keep in mind that pic: and fig: are also 
checked as prefix.

Thank you Hans, it works again!

I see from looking at the source code that prefixes are used
to localize references. There is also some sort of automatic
prefixing mechanism. Can someone explain this more as it is
not clear to me from documentation in the source code.

Indeed, I have for a long time used keys such as
\placefigure [here] [fig:Einstein] {caption} {\externalfigure [Einstein]}
and
\startchapter [reference=ch:Einstein,title=Einstein]
also
\placeformula [eqn:Einstein]
    \startformula E = mc^2 \stopformula
etc.
where the "prefix" is just a label uniquely identifying the tag,
thus avoiding multiple definitions.
(I also do this practice in LaTeX using \label{})
I was unaware that ConTeXt handled this explicitly.

using fig: etc is fine

there's also

\setupreferencingp[prefix=whatever]

and that will automatically prepend whatever: (so whatever:fig:...}

this is handy in large docs build from smaller pieces ... less clashes

there's also setuphead[...][referenceprefix=...] as well as some more 
trickery (dates from way back, when er were making huge complex 
interactive documents)
