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
