We may end up supporting that for another reason - handling
horizontal inheritance.

Hello list
I am having a question relating unbound ObjEntities. Probably this was
already discussed before but I was not able to find much in the
archives,
so here goes my question.
Is it possible to extend Cayenne in a manner so that I could model an
ObjEntity which is not bound to a DBEntity? One of the usage
scenarios is
when I have a query frame where the user can enter some values
which are
then interpreted by the business logic (search frame to query a
user table
as example). The benefit of using unbound tables is that the UI
already
has a renderer which knows how to render/display an ObjEntity (if
there is
a corresponding DataView) and all the data binding to the Swing
components
would be available as well. That would be a huge time saver for the
developer.
Another scenario is when I have a report engine which knows how to
render
ObjEntities with DataViews. I could then create a dynamic ObjEntity
which
is not bound to a DB Entity but filled by my own code and which is
then
handed over to the report engine.
Was such an extension discussed before? What are your thoughts on
this?

Adrian
