Didn't knew that, since 3.0 should implement JPA one day... so I though
it was the first Cayenne to take advantage of Java 5, avoiding many
casts like :
* MyClass newObject =
context.createAndRegisterNewObject(MyClass.class)
* for (MyClass obj : context.performQuery(new
SelectQuery(MyClass.class, qualifier)) ...
* List<InvoceLine> lines = invoice.getLines();
* etc...
So now I know I'll have to keep my helper classes and my custom
..uppressWarning("unchecked") List<XXX>' templates...

I know that. This quick start was in the 3.0 doc.

My case is not about all the ways to empty tables... but about
demonstrating at the very beginning that Cayenne allows you to be very
generic. And I wrote that that I may be going to far.

I'm not telling the original poster that his coding style isn't good,
I'm just sending my point of view. This is the very reason why I'm
posting this in user and not dev... Anyway, Cayenne is on my classpath
since 1.2 betas, just look at the mailing list archives in maybe 2k4 (my
case about cayenne in Tapestry-users :
http://mail-archives.apache.org/mod_mbox/tapestry-users/200501.mbox/%
3C1107213773.17348.52.came..wrk.nwrk%3E).
I did a lot of work with the Cayenne's model to build tools like
Dia-UML-to-Cayenne mapper, database synchronizer
(http://www.mail-archive.com/use..ayenne.apache.org/msg01257.html) and
automated CRUD tests
(http://objectstyle.org/cayenne/lists/cayenne-devel/2005/06/0036.html).
All this posted on the ML.
