[NTG-context] index entries postponed if sections are empty

Hi, I‘m despairing about my index – some sections contain only an image (\externalfigure), but I need to set several index entries for the image contents. The index entries get postponed until after the next chapter. I guess the problem is that there’s no (text) content, but \par and \strut didn’t help. The MWE shows that index entries in empty sections are ignored, i.e. “Something” is supposedly only on p.6: \usemodule[visual] \starttext \dorecurse{5}{% \startchapter[title={\recurselevel}] \dorecurse{5}{% \startsection[title={\fakewords{3}{5}}] \index{Something}\index{A\recurselevel} } \stopchapter } \completeindex \stoptext What can I do?
