Hi, the following code results in an empty output when typeset by MKIV on my system: \usemodule[bib] \setuppublications[criterium=all] \setupbibtex[database=mypublications] \starttext \placepublications \stoptext \end The same code typeset with MKII produces the list of all bibliography items in the .bib file, as expected. Is it a bug or is MKIV different in some respect? If it is a bug, is there a workaround? What I use: ConTeXt ver: 2010.05.24 13:05 MKII ConTeXt ver: 2010.05.24 13:05 MKIV LuaTeX, Version beta-0.60.1-2010042810 Below you find the log file.
