Hello,

I have a problem to use the calendar from the Tikz/Pgf module; here is a minimal example:

%--------------------------------------- \usemodule[tikz] \usetikzlibrary[calendar]

\starttext This should works: \blank \tikz \calendar[dates=2000-01-01 to 2000-01-31,week list]; \blank but this does not ! \stoptext %---------------------------------------

I'm using MKII (2010-05-24) from TeX Live 2010 (Note however that I had the same problem with TeXLive 2009). The error is when the calendar library is loaded:

! Undefined control sequence. l.36 \let\tikz@atbegin@day=\pgfutil @empty

I have tried the Tikz distribution from TexLive, the latest Tikz distribution from the suport Tikz page, and the distribution from the module made for ConTeXt, but the problem remains. In the past (last academic year, in may), this worked well, but I'm not able to find what has changed.

The example still works in mkiv. (Minimal distribution, fairly recent)

The following trick solves the problem temporary, but it should be fixed somewhere in the source if possible. I'm not sure if it is the fault of ConTeXt or the fault of TikZ:

\unprotect \usemodule[tikz] \usetikzlibrary[calendar] \protect

\starttext

This should works: \blank \tikz \calendar[dates=2000-01-01 to 2000-01-31,week list]; \blank but this does not ! \stoptext To me this looks like
