[Hibernate-JIRA] Updated: (EJB-46) Property Validation should happen after PrePersist/PreUpdate

I'm not sure if there's a good reason for this, but I think it would be particularly convenient if this behavior was reversed. IMHO it seems to better fit the semantics of the PRE callbacks, and it would allow callbacks to make modifications to the objects before they are persisted or updated -- modifications that might in turn effect the property validation Hibernate is doing. > The "audit" example in the entity manager documentation does make changes to the object. What if these changes had effected the property validation done before the callback occurred? What if the object was in an invalid state before the callback, but a valid state after the callback? The latter case is what I think would be conveniently handled if hibernate did its property validation after prepersist/preupdate. > Just two cents worth, obviously there are workarounds. This EJB3 stuff is looking great. > Ryan > P.S.

RE: Query.list() returns one item (as expected) but that item is null (which is unexpected)

by Mehdi.Rakhshani＠gxs.com

I have a simple query that when I execute in sqlplus returns one record as expected. When I run the same query using hibernate and java, I get a list back which has one record, but that record is null. I wrote the same search using Criteria and hibernate complains that the column name cannot be resolved. Whether I use the "name" attribute or the "column" attribute of the property it makes no difference. Hibernate 3.1: 1,971,632 hibernate3.jar, Windows XP, Oracle DB HBM snippet: <hibernate-mapping package="com.gxs.iefe.alias"> <class name="AliasTable" table="IEFE.ALIAS_TABLE" > <meta attribute="sync-DAO">false</meta> <composite-id name="id" class="AliasTablePK"> <key-property name="owningSystem" column="OWNING_SYSTEM" type="string" /> <key-property ... Code snippet using query: q = theSession.createQuery( "from AliasTable where OWNING_SYSTEM = :sys and OWNING_ACCOUNT is null and OWNING_USER_ID is null and TABLE_NAME = :tbl" ); q.setString( "sys", theOwner.getSystem() ); q.setString( "tbl", theTable ); // Using q.uniqueResult() produces the same behavior List anAliasTableList = q.list(); if ( null == anAliasTableList || 0 == anAliasTableList.size() ) throw new Exception( "Null list" ); // Code that verifies list size has been removed. "Null list element" is thrown. anAliasTable = (AliasTable)anAliasTableList.get( 0 ); if ( null == anAliasTable ) throw new Exception( "Null list element" ); Code snippet using criteria: Criteria aCriteria = theSession.createCriteria( AliasTable.class ); // Specifying neither property name nor property column works: could not resolve property: owningSystem of: com.gxs.iefe.alias.AliasTable //aCriteria.add( Restrictions.eq( "OWNING_SYSTEM", theOwner.getSystem() ) ); aCriteria.add( Restrictions.eq( "owningSystem", theOwner.getSystem() ) ); aCriteria.add( Restrictions.isNull( "owningAccount" ) ); aCriteria.add( Restrictions.isNull( "owningUserId" ) ); aCriteria.add( Restrictions.eq( "tableName", theTable ) ); // Retrieve the data List anAliasTableList = aCriteria.list(); Any idea why?
