DOCBOOK-APPS: Tables in print output

Hi,

I have trouble producing tables in print output. I get only one table
row.
And this message:
openjade:/home/documentation/DocBook/dsssl/print/dbtable.dsl:404:5:E:
flow object not accepted by port; only table-column flow objects
followed by table-row or table-cell flow objects allowd

I am using XML DocBook 4.1.2, Openjade 1.4 and the Norman Walsh
DSSSL-Stylesheets 1.71.

Does anybody know how to solve this problem?

Thanks,

Katharina
