> The criteria countDistinct() does not generate the correct query:
> criteria.setProjection(Projections.countDistinct("id"));
> generates: select count(id)
> instead of: select count(distinct id)
> This used to work in version 3.3.2-GA with toSqlString(). This method is missing in 3.5.0
> Working version in 3.3.2-GA: http://viewvc.jboss.org/cgi-bin/viewvc.cgi/hibernate/core/trunk/core/src/main/java/org/hibernate/criterion/CountProjection.java?revision=14993&view=markup
> Broken version in 3.5.0: http://viewvc.jboss.org/cgi-bin/viewvc.cgi/hibernate/core/trunk/core/src/main/java/org/hibernate/criterion/CountProjection.java?revision=17874&view=markup
