rich:tree component don't see what my class implements TreeN
Hello!
My configuration:
JSF: 1.2._04
JBoss SEAM: 1.2.1.GA
RichFaces: 3.0.1-20070402
JVM: Sun RI JVM 6.0
OS: Fedora Linux
I am trying use rich:tree component, but afoul with next trouble.
I have class which implements TreeNode interface:
------------------------------------------------
@Name("treeMenu")
public class TreeMenu implements TreeNode, Serializable {
private static final long serialVersionUID = 6980908422325671888L;
private Map sections = null;
private long nextId = 0;
public long getNextId() {
System.out.println("call method getNextId()");
return this.nextId++;
}
private Map getSections() {
System.out.println("call method getSections()");
if (this.sections == null) {
this.sections = new HashMap();
this.initData();
}
return this.sections;
}
public void addSection(final Section section) {
System.out.println("call method addSerction()");
this.addChild(Long.toString(section.getId()), section);
section.setParent(this);
}
public void addChild(final Object identifier, final TreeNode child) {
System.out.println("call method addChild()");
this.getSections().put(identifier, child);
}
public TreeNode getChild(final Object id) {
System.out.println("call method getChild()");
return (TreeNode) this.getSections().get(id);
}
public Iterator getChildren() {
System.out.println("call method getChildren()");
return this.getSections().entrySet().iterator();
}
public Object getData() {
System.out.println("call method getData()");
return this;
}
public TreeNode getParent() {
System.out.println("call method getParent()");
return null;
}
public boolean isLeaf() {
System.out.println("call method isLeaf()");
return this.getSections().isEmpty();
}
public void removeChild(final Object id) {
System.out.println("call method removeChild()");
this.getSections().remove(id);
}
public void setData(final Object date) {
}
public void setParent(final TreeNode parent) {
}
public String getType() {
System.out.println("call method getType()");
return "treeMenu";
}
private void initData() {
.....
}
}
------------------------------------------------
But, when I try to adress at my.xhml page JBoss throw nest stack with errors:
