Dan,
Like I said in my reply to Joe, my head hurts of all the JS framework
choices :-) I'd like us to design a service that can be integrated as
a data layer into the most of the leading frameworks... (if this is
even possible...) In this respect your experience with Spry and other
things JS may be helpful to us. So feel free to jump on the
discussion, that I hope will continue on dev.

Hi Joe,
not exactly what you're asking for, but my experiences... As regards
one-directional AJAX (server -> client), I use Cayenne with Adobe
Spry's (http://labs.adobe.com/technologies/spry/home.html) XML
DataSets and I've been very happy with this combination so far.
Cayenne's suport for XML serializarion is a big plus for that. I
studied Ext for a while, but stayed with Spry, as it is more low-level
and allows me to play with it more. Moreover, I like their idea of
using custom XML namespaces on the client side instead of writing a
lot of JS. I've written a JSP tag for that and now creating a new
paginated AJAX-enabled list of records with deleting capabilities
means writing one tag for me (as for the client side, and no editing).
As for the other direction (e.g. ajax command to delete a row), I'm
using jQuery and the plugin that integrates Taconite with it. I like
Taconite's principle a lot. We've used DWR at work (not with cayenne)
and I've been quite amazed, but for now I don't use it (maybe again
because Taconite shields me from JS most of the time).

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:
http://extjs.com/deploy/dev/examples/grid/edit-grid.html
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.
http://getahead.org/dwr
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.
