Hi all,
do you know/use/point out an Eclipse framework that, starting from an EMF ecore, can generate an out-of-the-box minimal CRUD (Create-Read-Update-Delete) RCP application for a database system with the following features?

- generated Views or Editor for the UI (not with Propery pages)
- EMF databinding
- Database persistence with Teneo or CDO
- EMF ResourceSet, EditingDomain and dirty management

Thank you very much

.... because CDO as well as Teneo know how to deal with EMF-Resources you
can use the generated editors from EMF-Edit with both of them.

Hi Tom,
thank you for the response, but the EMF-Edit generated plug-in works with the default EMF Resource implementation, that is XMI.
What are the steps for modify the generated plug-ins in order to use a different EMF Resource implementation like the Teneo o CDO one?

Thank you
Cheers

Vincenzo

There where the generated source loads the XMI you need nothing more
than replace it with: http://wiki.eclipse.org/Teneo/Hibernate/Tutorial

Hi Tom,
thanks! Indeed it took a while to find the right place to change things,
but in the end we were able to use the generated EMF-Editor plugin with Teneo for managing the database!
And that's great: a CRUD for the EMF model at zero-cost!

Now we would like to move a step forward.
In fact, the generated multipage editor allows editing with the use of the Properties, while we would like to have a form-like UI, that is, a View or Editor with labels, text fields and so on.

We tried to examine the code of the generated multipage editor in order to replicate the logic in a brand new custom editor (or view), but we did not find how to do that (the generated code for an ecore with a couple of classes consists of more than 1600 lines of code).
What are the minimum steps in order to "plug" a simpler custom view or editor to the underlying generated plug-ins?

Thank you
Vincenzo

EEF but the really most promising project for you is
http://www.eclipse.org/projects/project_summary.php?projecti d=modeling.emft.emf-client
and http://code.google.com/p/unicase/wiki/ECPNavigation
