[NTG-context] [pagenumbers in pdf]

When I generate a serie of TEXpages, those pages end up with the same page number in the pdf. 1, 1, 1 \starttext \def\blz{\begingroup \startTEXpage 1 2 3 \stopTEXpage \endgroup} \blz \blz \blz \stoptext If I insert a \strut at the start, I get pagenumbering 1, 2, 3, 1 \starttext \def\blz{\begingroup \startTEXpage 1 2 3 \stopTEXpage \endgroup} \strut \blz \blz \blz \stoptext As in most software, there is a probable reason for that :-) But how to get the pages numbered 1, 2, 3 without an empty page at the start? .F
