Dear ConTeXt folks,


using

        ConTeXt  ver: 2011.06.19 14:17 MKIV  fmt: 2011.6.21  int: english/english

the following minimal example taken from the Wiki page [1] does not work
as expected.

--- 8< --- minimal example --- >8 ---
\starttext
The famous result (and again) is given by
\placeformula[formulalabel]
\startformula
c^2 = a^2 + b^2.
\stopformula
And now we can refer to formula \ref[formulalabel] (ref).
And now we can refer to formula \in[formulalabel] (in).
\stoptext
--- 8< --- minimal example --- >8 ---

`\ref` does not seem to find the label for the equation. `\in` does
work.


Thanks,

Paul

The example is wrong, \ref expects two arguments: http://wiki.contextgarden.net/Reference/en/ref
