Identity columns support is definitely in the plans and is important,
but unfortunately there is no date set for it yet.
BTW, I just wrote a small test application to see the level of support
of identity keys on SQLServer at the JDBC level. MS "official" driver
failed miserably (java.lang.AbstractMethodError:
lang/String;I)Ljava/sql/PreparedStatement), while open source jTDS
worked like a charm, returning the keys.
So what are your options now:
1. Wait till sometime in the fall I guess.
2. Implement it yourself (ideally contributing it back to Cayenne),
with the help of Cayenne developer community. Please post any related
questions on cayenne-devel list.
3. [putting on my "ObjectStyle LLC. does commercial Cayenne support"
hat :-)] This can be implemented on commercial basis, probably like 3-4
days of work (and if this is released back to Cayenne, the fee will
definitely be lower).
I hope you understand that I am suggesting (3) not cause it is so
convenient for me to withhold the features and charge for their
development (quiet the opposite - I want all needed features done
ASAP), but as an open source project we have limited capacity and are
pretty busy these days. There has to be an incentive to reprioritize.
