Has anyone gotten ExtJS-grid playing well with Cayenne via JSP? I got
the demo (below) working on my Tomcat server using a static XML file
as the datasource, but that is far removed from bi-directional
communication with Cayenne. Check out the field-editing capabilities
of this interface:

The problem is that ExtJS tutorials fall somewhat short of proving
that ExtJS-grid can interoperate with an ORM (even though they claim
that it works with JSP). There is one comment about using DRW to
accomplish this easier.

But again, I have seen no working example that proves the concept.
If the answer is no, then I will continue hammering on it and then
post the results. My theory is that an "Editable Grid" (aka
spreadsheet-interface-pattern), JSP, and Cayenne would be a powerful
combination.

PS I have been using Cayenne for a few months now in development, and
it is one of the most stable components I have tested to date.
