Re: [eclipselink-users] databinding + eclipselink 
Tim,

may be I'm not clear enough or missing something: 

the refreshing of my objects from database will be done by a job at 1 minute intervals by executing a ReadAllQuery at my session (read-only, no cache checking). The resuling complex object graph is changing over the time - both in the size and the status. Due to these changes involving some but not all objects my UI elements should be notified and updated if the have focus at changed objects.

To my mind the EclipseLink the change tracking could offer a starting point but it isn't obvious to me if and how it would act with read-only queries.

Hi,
Thomas you can absolutely use databinding with EclipseLink!

I've used EclipseLink with JFace Databinding in an RCP application
quite successfully.

It works great with Tables and with regular fields -- you do have to
implement Property Field Listeners on your entities to be compatible
with JFace Databinding, but that's easy enough to do.

Take a look at our RCP Example at my blog:

http://www.weheartcode.com/2008/08/27/eclipselink-in-j2se-rcp-applications/

It uses JFace databinding on tables and fields I believe.

Let me know if you have any questions.

Tim

Is there a way to observe and propagate changes at/in the objects due to the refresh as eclipse databinding offers? Perhaps its possible to couple eclipselink and eclipse databinding seamlessly?
