[hibernate-issues] [Hibernate-JIRA] Assigned: (HHH-142) Property with Duplicated name

Property with Duplicated name ----------------------------- Key: HHH-142 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-142 Project: Hibernate3 Issue Type: Improvement Components: metamodel Affects Versions: 3.0 beta 4, 3.1 rc3 Environment: WinXP, Hibernate 3 from CVS (2005.02.19) J2SE 5.0 Reporter: Konstantin Sharenkov Assignee: Diego Pires Plentz Priority: Minor Fix For: 3.0 rc 1 When I tryed to Implement Parametrized user type to support Native J2SE 5.0 Enums as VARCHAR. I randomply detect that I able to set 2 properties with the same name at one class. <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.enterra.tth.po" > <typedef class="com.enterra.tth.po.NativeEnumType" name="ActorAttributeType"> <param name="enumClass">com.enterra.tth.po.ActorAttribute$Type</param> </typedef> <class name="ActorAttribute" table="t_actor_attribute" optimistic-lock="version" > <cache usage="read-write"/> <!-- Standrt part of mapping --> <id name="id" type="string" > <column name="f_id" sql-type="char(32)" not-null="true"/> <generator class="uuid.hex"/> </id> ... <property name="type" type="ActorAttributeType"> <column name="f_type" sql-type="varchar"/> </property> <property name="type" type="string"> <column name="f_value" sql-type="varchar"/> </property> </class> </hibernate-mapping> See property "type". Aclually getter and setter use com.enterra.tth.po.ActorAttribute$Type But both in background will use VARCHAR. As result I recieved class cast exception com.enterra.tth.po.ActorAttribute$Type to String. I think it will be better to disable duplicated properties. Or generate warning may be. Thanks. PS. After I update Hibernate 3 from cvs today and rebuild it I have started to recieve following exception. java.lang.NullPointerException at org.hibernate.tuple.PojoTuplizer.handleProperty(PojoTuplizer.java:82) at org.hibernate.tuple.AbstractTuplizer.<init>(AbstractTuplizer.java:77) at org.hibernate.tuple.PojoTuplizer.<init>(PojoTuplizer.java:53) at org.hibernate.tuple.TuplizerLookup.create(TuplizerLookup.java:45) at org.hibernate.tuple.EntityMetamodel.<init>(EntityMetamodel.java:202) at org.hibernate.persister.entity.BasicEntityPersister.<init>(BasicEntityPersister.java:398) at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:104) at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:55) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:198) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1043) Hope it will help you too.
