This is my view
<!-- Images -->
<c:choose>
<c:when test='${galleryPage.images == null}'>
Empty Gallery
</c:when>
<c:otherwise>
<c:forEach var="image" items="${galleryPage.images}">
Image Id is ${image}.id
</c:forEach>
</c:otherwise>
</c:choose>
<!-- End Images -->
And my backing bean
@Entity
@Name("galleryPage")
@Scope(SESSION)
@Inheritance(strategy = InheritanceType.JOINED)
public class GalleryPage extends Page {
private String description = null;
private Set<Image> images = new HashSet<Image>(0);
@NotNull
@Length (min = 5, max = 500, message = "Description is required and must be at most {max} characters long.")
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
@OneToMany(cascade={CascadeType.ALL}, fetch=FetchType.EAGER, mappedBy="galleryPage")
public Set<Image> getImages() {
return images;
}
public void setImages(Set<Image> images) {
this.images = images;
}
public void addImage(Image image) {
this.images.add(image);
}
public void removeImage(Image image) {
this.images.remove(image);
}
Any ideas people? TIA
