The SOBF tool (Security Officers Best Friend, Open Source tool for
assessing information security risk) is heavily based on DataViews and the
DataViews saved me many hours of headaches and work.
Basically it is the idea to create DataViews for DataObjects. Taking
these view definitions it is possible to program a databound JList in a
few minutes. For the SOBF tool we currently work on creating a renderer
based on DataViews which can generate detail edit frames and which can
create JasperReports XML formatted files. This would allow us to create
new edit/view forms and printable representations of these in no time.
The idea is this: When the data model changes (at least when talking about
simple foreign key constraints and table changes) we will need no
progamming. We will just update the respective DataView and the renderer
does the rest.

I would suggest to move DV "out of the way" so that it is not hurting the
normal Cayenne development. But please keep DataViews supported. I am
currently in the process to switch to Cayenne 3.x because I absolutely
need the Lifecycle Callbacks (generating uuid formated key when creating a
new object and updating the last_updated field before committing changes).
Because the SOBF tool is that much depending on DataViews I would very
much like to see them at least not removed. I would hate to have to redo
everything I already programmed only beause of DataViews being removed
from Cayenne.
