Data model object types issue with Id and Generics -------------------------------------------------- Key: HHH-3758 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3758 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Hibernate 3.2.6.ga, Windows XP, Maven 2.0.9, JDK 1.6.0_11 Reporter: Giovanni Azua Wanting to have a reusable base for Identifiable data model Object types and at the same time a stronger type checking (e.g. Generic DAO implementations) I introduced the interface and Abstract class below. The problem is that my working models as soon as I extend from AbstractIdentifyable or just implement Identifyable, my test cases break with the following: org.perfectjpattern.jee.api.integration.dao.DaoException: org.hibernate.exception.SQLGrammarException: could not insert: [example.datamodel.Person] I suspect this is related to some kind of Hibernate use of Reflection that can't find in the model supertypes a definition of setId that matches exactly the type it expects e.g. Long but it is a generic parameter. regards, Giovanni public interface Identifyable<Id extends java.io.Serializable> { public Id getId(); public void setId(Id anId); } and base abstract reusable implementation public abstract class AbstractIdentifyable<Id extends java.io.serializable> implements Identifyable<Id> { // ... implements the reusable Identifyable methods } -- 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
