[jboss-user] [EJB 3.0] - Deployment error mapping a parent/child related entity

I have a self-referencing entity hierarchy like that: @Entity | @Inheritance(strategy=InheritanceType.JOINED) | public abstract class HrcEntity<T extends HrcEntity> extends ComplexEntity | { | private List<T> children; | private T parent; | | @OneToMany(mappedBy="parent", cascade=CascadeType.REMOVE) | public List<T> getChildren() | { | return children; | } | | @ManyToOne(fetch=FetchType.LAZY) | public T getParent() | { | return parent; | } | | } | | @Entity | @Inheritance(strategy=InheritanceType.JOINED) | public class Node extends HrcEntity<Node> | { | ... | } so I can do for example: List<Node> children = node.getChildren(); but deploying these entities I get the error: "java.lang.IllegalStateException: Property parent has an unbound type and no explicit target entity." from my point of view this should work - there is is a table HrcEntity in db and hibernate simply has to map the column "parent" to the same table. btw. - if I make HrcEntity non-generic it works, but I get very ugly code with lot of casts and "instanceof" any comments? thanks!
