[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-2336) paremeterizable and typedef-able UserCollectionType (Holger Brands)

paremeterizable and typedef-able UserCollectionType (Holger Brands) ------------------------------------------------------------------- Key: HHH-2336 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2336 Project: Hibernate3 Issue Type: Patch Components: core Affects Versions: 3.2.1 Environment: Hibernate 3.2.1, independent of database platform Reporter: Holger Brands Assignee: Steve Ebersole Fix For: 3.2.4 Attachments: bug2336.patch, usercollectionwithparameters.zip Currently, it's required to specify a class name as value for the collection-type attribute of a collection mapping. Therefore you can't use a typedef'ed type as collection-type and consequently you can't pass parameters to a custom collection type. Please enhance the support for custom collection types such that you can do something like this: <typedef name="MyEventListType" class="ca.odell.glazedlists.hibernate.EventListType"> <param name="category">Test</param> </typedef> <class name="User" table="`USERS`"> <id name="userName" column="USERNAME"/> <!-- mapping a value collection --> <list name="nickNames" table="USER_NICKNAMES" collection-type="MyEventListType"> <key column="USER_ID"/> <list-index column="DISPLAY_ORDER"/> <element column="NAME" type="string" length="50"/> </list> </class> Currently this mapping fails with this exception: org.hibernate.MappingException: user colllection type class not found: MyEventListType at org.hibernate.type.TypeFactory.customCollection(TypeFactory.java:267) at org.hibernate.mapping.Collection.getCollectionType(Collection.java:348) at org.hibernate.mapping.Collection.getType(Collection.java:340) at org.hibernate.tuple.PropertyFactory.buildStandardProperty(PropertyFactory.java:120) at org.hibernate.tuple.entity.EntityMetamodel.<init>(EntityMetamodel.java:163) at org.hibernate.persister.entity.AbstractEntityPersister.<init>(AbstractEntityPersister.java:425) at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:109) at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:55) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:226) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1291) at ca.odell.glazedlists.hibernate.AbstractHibernateTestCase.buildSessionFactory(AbstractHibernateTestCase.java:133) at ca.odell.glazedlists.hibernate.AbstractHibernateTestCase.setUp(AbstractHibernateTestCase.java:167) at junit.framework.TestCase.runBare(TestCase.java:125) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at junit.framework.TestSuite.runTest(TestSuite.java:208) at junit.framework.TestSuite.run(TestSuite.java:203) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:128) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Caused by: java.lang.ClassNotFoundException: MyEventListType at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:268) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) at org.hibernate.util.ReflectHelper.classForName(ReflectHelper.java:100) at org.hibernate.type.TypeFactory.customCollection(TypeFactory.java:264) ... 24 more Also see the coresponding forum entry for details: http://forum.hibernate.org/viewtopic.php?t=969043 Attached is a test case that demonstrates this problem. It's a modified copy of the existing "usercollection" test case in the Hibernate 3.2.1 distribution. Just copy the directory into your org.hibernate.test directory and include it in your testsuite. As I'm not familiar enough with the internals of Hibernate, I have no patch at hand, sorry. Resolving this issue would enhance mapping flexibility for custom collection types because you would be able to pass parameters as it's possible right now for UserTypes and CompositeUserTypes.
