Hi there,

i upgraded from Hibernate 3.2.6 to Hibernate 3.5. Up to now, i get this code working:

Code:

crit.setProjection(Projections.rowCount());
Integer result = ((Integer)crit.list().iterator().next()).intValue();   

3.5. tells me, that rowCount is returned as a Long, didnt find that in the javadoc. Is it an API change, when did it happen?

edit: and are there any other changes like this i need to know about (errors obv appearing at runtime only, dont want my customers to find all the errors for me :) )

Seems like it has been a known issue a long time that was fixed in 3.5. A similar change was made for HQL a long time ago. Read http://opensource.atlassian.com/project ... e/HHH-1724
for more information. There is a wiki page (http://community.jboss.org/wiki/Hiberna ... tionGuides) collecting migration information, but none yet for Hibernate 3.5.

Ok, thx 4 your reply. Is it possible to name a date, when the migration guide to 3.5. will be available?
