Hello All,
I am implementing an Entity class as below
@Entity@Table(name=*"Employee"*)@IdClass(EmployeeEntityPK.*class*)*public
class *EmployeeEntity *extends *AbstractEntity {
//with no attributes only getter / setter
My AbstractEntity is a @MappedSuperClass with one @Id,@Column and other
@Columns defined
Also I have EmployeeEntityPK which has
@Id@Column(name = *"empId"*)*private *Integer *empId*;
When I deploy my application I get exception as
Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:547) [rt.jar:1.6.0_17]
at java.util.ArrayList.get(ArrayList.java:322) [rt.jar:1.6.0_17]

org.hibernate.cfg.AnnotationBinder.mapAsIdClass(AnnotationBinder.java:824)
at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:671)
AnnotationBinder.getUniqueIdPropertyFromBaseClass has a check as follows
*if *( elementsToProcess.getIdPropertyCount() == 1 ) {
which checks if my Entity has only one ID attribute, if so then
getsUniqueId from base class.
In my case I dont have any ID attribute in my EmployeeEntity so the I get
ArrayIndexOutOfBoundException.
Ideally in getUniqueIdPropertyFromBaseClass, baseClassElements should be
processed from AbstractEntity. Why its processing elements from
EmployeeEntity? Is this expected behaviour
I have added my source code to
https://github.com/surendrand/hibernate-entity-mapping for further reference
