@SuppressWarnings didn't exist when the template was created... it
probably should be there. In fact, in the somewhat similar version of
the template I use, it is :) Just the same though, there's a million
other places in Cayenne where you can't get rid of the warnings.

I'm not entirely sure its possible to have a 100% type-safe Cayenne.
Areas of particular concern are named queries (how to get the string
version of the query root to the compiler), the String-version of
performQuery and XML deserialization.
The way generics were implemented (with erasure) doesn't render them
useless, but it does mean they can't be used everywhere. I'd love to
see that warning removed entirely in JDK6 but I'm not holding my
breath!
