The magic expansion hit me again, I should've known it.

Thank you very much!
Actually, in the real environment I needed the \expanded at another  
place:

\def\Sender#1#2#3{\setvalue{SenderKey#1}{#2}\setvalue{SenderVal#1}{#3}}
\def\GetSenderLine#1{\bTR\bTD\doiftextelse{\getvalue{SenderKey#1}}	 
{\getvalue{SenderKey#1}:}{}\eTD\bTD\getvalue{SenderVal#1}\eTD\eTR}
% initialize values (not even needed)
\dostepwiserecurse{1}{9}{1}{
     \Sender{\recurselevel}{}{}
}

\startsetups sendertablesetup
	\setupTABLE[frame=off]
	\setupTABLE[x][1][width=\senderkeywidth, align=left, style={\keystyle 
\strut}]
	\setupTABLE[x][2][width=\sendervalwidth, align=right, style= 
{\valstyle\strut}]
	\bTABLE
\dostepwiserecurse{1}{9}{1}{% count from 1 to 9, step 1
	\expanded{\GetSenderLine{\recurselevel}}
}
	\eTABLE
\stopsetups
