[Hibernate-devel] Recent development

[Gavin_King/Cirrus%<CI...@ci...>]

I spent much of the weekend programming and and added support for queries
returning properties and aggregate values. These queries only work with
iterate() currently ( ie. not with find() ).

You can write stuff like

 select foo.id, foo.name from foo in class Foo where foo.bar.name = 'bar'

 select count(*), count(distinct foo.baz), sum(foo.count), foo.type from
foo in class eg.Foo group by foo.type

This fills a very old feature request. Implementing this required some
reworking of the query translater. If people here could grab a CVS snapshot
and test this new implementation against their current system (and also
test the new functionality) I would really appreciate that.

I also fixed a problem with JNDI lookup of SessionFactory and fixed some
problems with lifecycle load() and onLoad() callbacks.

Earlier in the week I changed the ordering in which save() and delete() are
cascaded to collections. This improves the behaviour where there are
not-null constraints. It also optimizes performance of one-to-many
bidirectional associations. However there is a (very) small possibility of
breaking existing code so be aware of that.

I want to release all this in version 1.0.1 (in the next couple of days).
