[NTG-context] Wrong pagenumber in index

Try 1: \starttext \section{Hello}\index{Hello} \page \index{world}world \page \completeindex \stoptext Result 1: hello 2 <- must be 1! world 2 Try 2: \starttext \section{Hello}\index{Hello} some text <- putting some text here \page \index{world}world \page \completeindex \stoptext Result 2: hello 1 <- ok world 2 It is ok but I didn't want to put text "some text" there. Try 3: Workaround: I put a tilde "~" instead of "some text": \starttext \section{Hello}\index{Hello} ~ <- putting the tilde here \page \index{world}world \page \completeindex \stoptext Result 3: hello 1 <- ok, with the tilde as a workaround world 2 I don't like such tricks - is there a ConTeXt-way?
