hbm2ddl.auto creates nullable column for primitive boolean on Derby database ---------------------------------------------------------------------------- Key: HHH-2644 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2644 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.0.ga Environment: Hibernate 3.2, Derby 10.2.20 Reporter: Noel Grandin Priority: Minor I have hibernate.hbm2ddl.auto=update and I have an existing database with existing tables. I updated one of the domain objects to have a new boolean field. When I started my app, it failed when it tried to load the domain object, with the following stacktrace: [0@15:39:41.551] !SE>: org.hibernate.PropertyAccessException: could not set a field value by reflection setter of peralex.grj8000.datastore.SweepJamBand.selected at org.hibernate.property.DirectPropertyAccessor$DirectSetter.set(DirectPropertyAccessor.java:82) at org.hibernate.tuple.entity.AbstractEntityTuplizer.setPropertyValues(AbstractEntityTuplizer.java:337) at org.hibernate.tuple.entity.PojoEntityTuplizer.setPropertyValues(PojoEntityTuplizer.java:200) at org.hibernate.persister.entity.AbstractEntityPersister.setPropertyValues(AbstractEntityPersister.java:3514) at org.hibernate.engine.TwoPhaseLoad.initializeEntity(TwoPhaseLoad.java:129) at org.hibernate.loader.Loader.initializeEntitiesAndCollections(Loader.java:842) at org.hibernate.loader.Loader.doQuery(Loader.java:717) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.loadCollection(Loader.java:1985) at org.hibernate.loader.collection.CollectionLoader.initialize(CollectionLoader.java:36) at org.hibernate.persister.collection.AbstractCollectionPersister.initialize(AbstractCollectionPersister.java:565) at org.hibernate.event.def.DefaultInitializeCollectionEventListener.onInitializeCollection(DefaultInitializeCollectionEventListener.java:60) at org.hibernate.impl.SessionImpl.initializeCollection(SessionImpl.java:1716) at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:344) at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86) at org.hibernate.collection.PersistentSet.iterator(PersistentSet.java:163) at peralex.client.control.Control.loadSelectedLibrary(Control.java:334) Caused by: java.lang.IllegalArgumentException at sun.reflect.UnsafeBooleanFieldAccessorImpl.set(UnsafeBooleanFieldAccessorImpl.java:62) at java.lang.reflect.Field.set(Field.java:656) at org.hibernate.property.DirectPropertyAccessor$DirectSetter.set(DirectPropertyAccessor.java:79) ... 36 more When I looked in the database, I noted that the table had been incorrectly updated with a nullable column for the new field. Using my debugger I confirmed that Hibernate was attempting to load a "null" value into a primitive boolean field. I worked around this by specifying @Column(columnDefinition="smallint not null default 0" ) private boolean selected; on my new field. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
