Hi, after couple hours i found solution. I am using mysql 5.0 with innoDB tables. So problem is in column type bit. It was always true, no matter if came from xwiki false argument. Xwiki, when you want to save some document, send right argument - hidden = false, but in mysql was always true. So i changed column type to tinyint and change hibernate connection parameters and it is works. :) Here is the solution : 1) represent booleans with TINYINT(1) 2) Add to cfg tinyInt1isBit=true & transformedBitIsBoolean=true: <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.tinyInt1isBit">true</property> <property name="hibernate.connection.transformedBitIsBoolean">true</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> 3) if running hbm2hbmxml, hbm2cfgxml, hbm2java use jdbcconfiguration, not configuration Solution original link http://opensource.atlassian.com/projects/hibernate/browse/HHH-468 I am not quite sure how it will work, when I run createWiki method? Any opinion? Jan On Tue, Jan 6, 2009 at 11:06 AM, Jan Kodera &lt;jan.kodera(a)gmail.com&gt; wrote:
