Hi all,

I got a strange "unknown reference" problem with the following simple example:

%%%%%%%%%%%%%%%%%

\starttext
\placeformula[eq:haha]
\startformula
a^2 + d^2 = c^2
\stopformula
haha \in[eq:haha]
\stoptext

%%%%%%%%%%%%%%%%%

After 3 iterations, I saw this message in the log file:
references      : unknown reference [][eq:haha]

I am using luatex beta-0.43.0-2009081911
Got the same problem with context version from 2009.6.14 to the latest beta.
I also tried deleting everything and re-install the minimal dist., but still can't solve the problem.  

I wonder if anyone else has this problem, or it only occurs to me. Thanks a lot.

regards,
shenchen
