Sylvain,
It seem to be great stuff, and something that we really need. But being
somewhat formalistic I'm a bit doubtfull about the timing. Ok, you
committed it before the freeze, but not in good enough time to make much
community involvment possible before the release.

Hi all,
Just in time before the code freeze deadline, I committed an
additional sample for CForms [1], which shows how, using JDBI [2] and
the Collection wrappers for container widgets and repeaters [3] and a
few conventions, writing simple CRUD applications with Cocoon is a
breeze. A simple flowscript, a form definition and a few templates and
you're done.
No Java classes, no binding file, no O/R mapping tool!
This sample is for now limited to editing one table, but I currently
use this approach on a small project with a few entities with
associations and compositions, and this works quite well. We'll have
to expand this sample to more than a simple table, but it's already a
good start to show people how to move away from the ugly
inserts-with-sqltransfomer pattern! And BTW I removed the previous
sample that was using that pattern...
This sample also uses some patterns (JS DAO objects) and conventions
(use of id for primary keys and xxx_id for foreign keys, generic
pipelines, etc) that we may want to factorize in some code generators
or run-time database introspection libaries. With Racoon, Crack and
this sample, Cocoon is back on the rails :-)
The live demo should be available soon at
http://cocoon.zones.apache.org/demos/trunk/samples/blocks/forms/sql/
Enjoy!
Sylvain
