Hi Alan, first of all i would like to thank you for your initiative in solve this huge problem. I used the HibernateBeanCloner and it worked very well :). Right now, i am facing a scenario where the object i would like to clone has an attribute and this attribute in an enumeration: @Entity public class Lights extends BasePojo { private static final long serialVersionUID = -3511966258961336172L; private Double powerDensityMax; private Double powerDensityMaxA; private Double powerDensityMaxB; private Double powerDensityMaxC; private Double powerDensityMaxD; @Enumerated(EnumType.STRING) @Column(nullable = false) private AssemblyType assemblyType; when i tried to clone it using HibernateBeanCloner i received the following error: java.lang.InstantiationException: br.org.certi.maestro.framework.lights.pojo.AssemblyType at java.lang.Class.newInstance0(Class.java:340) at java.lang.Class.newInstance(Class.java:308) at org.cloner.deep.HibernateBeanCloner.cloneBean(HibernateBeanCloner.java:13) at org.cloner.deep.DefaultCloner.doclone(DefaultCloner.java:42) at org.cloner.deep.DefaultCloner.cloneFields(DefaultCloner.java:69) at org.cloner.deep.HibernateBeanCloner.cloneBean(HibernateBeanCloner.java:23) at org.cloner.deep.DefaultCloner.doclone(DefaultCloner.java:42) at org.cloner.deep.DefaultCloner.cloneFields(DefaultCloner.java:69) at org.cloner.deep.HibernateBeanCloner.cloneBean(HibernateBeanCloner.java:23) at org.cloner.deep.DefaultCloner.doclone(DefaultCloner.java:42) at org.cloner.deep.DefaultCloner.cloneFields(DefaultCloner.java:69) at org.cloner.deep.HibernateBeanCloner.cloneBean(HibernateBeanCloner.java:23) at org.cloner.deep.DefaultCloner.doclone(DefaultCloner.java:42) at org.cloner.deep.DefaultCloner.cloneFields(DefaultCloner.java:69) at org.cloner.deep.HibernateBeanCloner.cloneBean(HibernateBeanCloner.java:23) at org.cloner.deep.DefaultCloner.doclone(DefaultCloner.java:42) at org.cloner.deep.DeepCloner.deepClone(DeepCloner.java:29) I think you can't instantiate an enumeration. Is there an workarround for it ? Best regards, Julio Helden.
