Hello ConTeXist.
I encountered a disproportion in initializing user counters. Why initialization at the beginning of the source text does not work and what is the mechanism of how the user counters work.

Thanx Jaroslav Hajtmar

Here is a sample example:

\definecounter[mycounter]

\def\getmycounter{\incrementcounter[mycounter]\getnumber[mycounter]}

\startbuffer[groups]
    \startxrow
    \startxcell \getmycounter\stopxcell
    \startxcell Content of column\stopxcell
\stopxrow
\stopbuffer



\starttext

%\setcounter[mycounter][0] % initializing at this point not working (the counter is 10 more than it should be). WHY?



\startxtable
    \startxrow
        \startxcell Column 1\stopxcell
        \startxcell Column 2\stopxcell
    \stopxrow

\setcounter[mycounter][0] % initializing at this point works fine
\dorecurse{5}{\getbuffer[groups]}
\stopxtable

\stoptext
