Hi,

I am porting a book from mkii to mkiv and I have found an issue with the
bibliography module. As Alan Braslau pointed out on 23 Mar, using
\placepublications [criterium=chapter] at the end of each chapter does not
show a cited reference if the reference is cited in an earlier chapter.

This may be a bug. Indeed, in mkii the reference was printed.

Is there any way in mkiv to "reset" the references at the end of each 
chapter to fix the issue?

Minimal example (sample.bib in tex/texmf-context/tex/context/bib/):

\setupbibtex[database={sample}]
\setuppublications[alternative=num,criterium=chapter]

\starttext
\chapter{One}
Some text.\cite[hh2010a]

\subject{References}
\placepublications[criterium=chapter]

\chapter{Two}
Another text.\cite[hh2010a]

\subject{References}
\placepublications[criterium=chapter]
\stoptext
