Hi, all.
I try to place a row number into the first column of my table.
I tried:
\definecounter[rownum][way=bytext,prefix=no]
\setcounter[rownum][0]
\starttext
\startxtable
      \startxrow
          \startxcell
              \incrementcounter[rownum]
              \rawcounter[rownum]
          \stopxcell
      \stopxrow
      \startxrow
          \startxcell
              \incrementcounter[rownum]
              \rawcounter[rownum]
          \stopxcell
      \stopxrow
      \startxrow
          \startxcell
              \incrementcounter[rownum]
              \rawcounter[rownum]
          \stopxcell
      \stopxrow
\stopxtable
And got:
7
8
9
If i place \setcounter[rownum][0] right after \startxtable, then i got:
1
2
3
Is this normal?
Yes, to fix it use
\startxcell
    \doifelsemode{*trialtypesetting}
      {0}
      {\incrementcounter[rownum]%
       \convertedcounter[rownum]}
\stopxcell
It seems that reseting once at table start is simpler, isn't it :-)?
Try your method with natural table or tabulate and it won't work anymore.

What is the difference between \rawcounter and \convertedcounter?
\rawcounter give me the plain number as i want.
In this case there is no difference but I suggest to use \rawcounter 
only when you need
the value of the counter, e.g. counter>... or counter=...

With \convertedcounter you have always the option to change the style of 
the value,
e.g. number conversion, prefixes etc.
...
What's about \newcount&\advance variant? Why it not work?
Short answer: expansion

You're using advance in a place where it is just ignored, there are ways 
to get rid
of these limitations with Luametatex but it's better to use 
\incrementcounter.
