I have tried to do this via a database action (org.apache.cocoon.acting.DatabaseAddAction)
and the following mapping:

AFAIK Database Action sets request attributes with the following
naming scheme


so you'd need to read from
org.apache.cocoon.acting.AbstractDatabaseAction:ProjectId and hope
that there's no request parameter of that name because it will have

Although still not prime time (helper handling needs complete redo)
you might want to check out the ModularDatabaseActions from the
scratchpad directory. I wouldn't advise using them for mission
critical work right now because they will change a bit before they
will migrate to the main trunk but it might still be worth a look.
Note that their descriptor format differs from the above.

BTW: one closing tag </table> seems to be misplaced above.
