[NTG-context] How to sort the reference by the cite sequence

I want to list the cited reference in the publication list, and numbered by the citing sequence. so I use \setuppublications[alternative=num,criterium=cite,sorttype=cite] But it seems the sequence is the one in the bbl file. So i add one line to generate a bbl file by the citing sequence. \setupbibtex[database={blabla},sort=cite] This time, there is even no bbl file generated. How do i get my publication list to what I want: numbered by the citing sequence in the text?
