[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4870) Cannot determine java-type from given member [null]

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4870?page=c... ] Andreas Joseph Krogh commented on HHH-4870: ------------------------------------------- Hi. I'm having this issue too, using 3.5-CR2. I should mention that I'm coding all my JPA2-entities in Scala-2.8.0-Beta1. Here's the TRACE-log: 2010-03-22 21:20:35,792 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | Starting attribute metadata determination [visitZipCode] 2010-03-22 21:20:35,792 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | Determined member [private java.lang.String no.officenet.origo.core.domain.model.company.Company.visitZipCode] 2010-03-22 21:20:35,792 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | determined type [name=string, class=org.hibernate.type.StringType] 2010-03-22 21:20:35,792 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | Building attribute [no.officenet.origo.core.domain.model.company.Company._no_officenet_origo_core_domain_model_calendarentry_CalendarEntry_company] 2010-03-22 21:20:35,792 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | Starting attribute metadata determination [_no_officenet_origo_core_domain_model_calendarentry_CalendarEntry_company] 2010-03-22 21:20:35,792 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | Determined member [null] 2010-03-22 21:20:35,793 | TRACE | main | org.hibernate.ejb.metamodel.AttributeFactory | determined type [name=component[companyId], class=org.hibernate.type.EmbeddedComponentType] 2010-03-22 21:20:35,793 | TRACE | main | org.hibernate.ejb.metamodel.MetadataContext | Completed entity [no.officenet.origo.core.domain.model.company.Company] ... ...<lots of Spring-messages "Destroying singletons in ..." ...

I can work around it by setting hibernate.ejb.metamodel.generation=disabled but it seems pretty hackish... This exact same code worked fine using Hibernate-core 3.3.2.GA, Hibernate-entitymanager 3.4.0.GA (JPA1) -- 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
