I have a class Listing with two collections reviews and discussions. Both Review and Discussion are subclasses mapped to the same table, distinguished by a discriminator column type. I am using Seam 1.2.1 but the problem is most likely related to the persistence mapping. Here are the mappings:
| @Entity | @Name("listing") | public class Listing implements java.io.Serializable { | ... | | @OneToMany(targetEntity = Review.class, cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "listing") | private Set<Review> reviews = new HashSet<Review>(0); | | @OneToMany(targetEntity = Discussion.class, cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "listing") | private Set<Discussion> discussions = new HashSet<Discussion>(0); | | } | | and | @Entity | @Name("review") | @DiscriminatorValue("review") | @Indexed(index="review") | public class Review extends com.n2.bo.UserContent implements java.io.Serializable { | ... | @ManyToOne(fetch = FetchType.LAZY) | @JoinColumn(name = "listingId") | private Listing listing; | } | | | @Entity | @Name("discussion") | @DiscriminatorValue("discussion") | @Indexed(index="discussion") | public class Discussion extends com.n2.bo.UserContent implements java.io.Serializable { | ... | @ManyToOne(fetch = FetchType.LAZY) | @JoinColumn(name = "listingId") | private Listing listing; | } | | @Entity | @Table(name = "user_content") | @Name("userContent") | @Inheritance(strategy = InheritanceType.SINGLE_TABLE) | @DiscriminatorColumn(name = "type", | discriminatorType = DiscriminatorType.STRING) | public class UserContent implements java.io.Serializable { | ... | } | | The problem I have is that we I load either reviews or discussions of a listing, both reviews and discussions are loaded into one collection, without checking for discriminator value. I verified this with sql statement there was no where type='review' or where type='discussion' clause. Any idea why? Thanks.
