Hi,
I'm simply trying to use formula...
I have a mapping class and a Unit Test who run OK
But when I had a simple <property with a formula I have that exception below
I just add :
Code:
<property name="candidatureEnCours" type="integer" formula="(select count(*) from candidatures)" >
</property>
I'm using Spring 2.5.4
Hibernate version: 3.2.6GA
Full stack trace of any exception that occurs:Code:

Name and version of the database you are using: MySQL 5.0.45
This sounds like
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2225
but in my case it-is the simpliest way to use formula so I guess I should have done something bad...
Thanks for your comment
