[NTG-context] Using module:bib

Hi, What is wrong with my attempt to create a bibliography and a reference to it? All I get is a (Xxxxx,0000) where I use \cite, and no list of references at \placepublications. %------------------------- \enableregime[utf] \mainlanguage[pt] \usemodule[bib] \setuppublicationlist[] \startpublication[t=manual, a=Fung, y=1993, n=1] \author{}[Y.C.]{}{Fung} \title{Mechanical Properties of Living Tissues} \stoppublication \starttext According to \cite[1]. \placepublications \stoptext %------------------------- Thanks, Maurício
