Hi, I have a JPA with associations inside a composite identifier, e.g. something like (from JBoss doc) @Entity | @AssociationOverride( name="id.channel", joinColumns = @JoinColumn(name="chan_id") ) | public class TvMagazin { | @EmbeddedId public TvMagazinPk id; | @Temporal(TemporalType.TIME) Date time; | } | | @Embeddable | public class TvMagazinPk implements Serializable { | @ManyToOne | public Channel channel; | public String name; | @ManyToOne | public Presenter presenter; | } | It works fine, just Eclipse shows error: Attribute "channel" has invalid mapping type in this context. Do you know, how to get rid of this error? Except switching off the JPA facet support for the project :-) Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247796#...
