Currently, there is no way for the Criteria API to support the following query:

select * from SomeTable where someBoolean is not true ;

Which would return all rows where someBoolean is null or false. Would it be possible to add Restrictions.isNotTrue (String propertyName), and its inverse, Restrictions.isNotFalse (String propertyName)? Currently, the workaround is to use a sqlRestriction (propertyName + " is not true") but this assumes that the physical column name matches the property name.
