[NTG-context] special macro problem again...

[Peter Münster]

It's a repost.
Does anybody have an idea to solve this problem?
If not, I'm going to buy the TeXbook...

I try to expose the problem a bit clearer:

\newcount\MyVersion
\def\MyMacro#1{%     This macro is somewhere in an environment file.
  \getgparameters[XXX][#1]
  \global\advance\MyVersion by 1
  \bTR \expanded{\bTD \the\MyVersion \eTD} \expanded{\bTD \XXXNumber \eTD}\eTR
}

\def\MyNumber#1#2#3{% This macro is a special one for the document.
  \doifmode{aaa}{#1}\doifmode{bbb}{#2}\doifmode{ccc}{#3}}

\enablemode[bbb]

\starttext
\bTABLE
\bTR \bTD Version \eTD \bTD Number \eTD \eTR
\MyMacro{Number=123}
\MyMacro{Number=\MyNumber{111}{222}{333}} % error: Incomplete \iffalse
\MyMacro{Number=456}
\eTABLE
\stoptext

Greetings, Peter
