RF 4 CR1: implementing and binding org.richfaces.model.TreeNode and org.richfaces.model.TreeDataModel in rich:tree

[codo]

Hello,

I'm trying to build a richfaces tree. When I implement the interface javax.swing.tree.TreeNode and bind it to the attribute "value" in rich:tree it works just fine. But when I implement org.richfaces.model.TreeNode or org.richfaces.model.TreeDataModel it doesn't work. It throws exception:

Is this a bug or I'm doing something wrong?

[ilya_shaikovsky]

please show the code.

Ok, I made project with simple demo of using the three models.

Here is the first one, implementing org.richfaces.model.TreeNode:

The Model:

package model;

import entities.Picture;

import java.io.Serializable;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.Iterator;

import java.util.List;

import java.util.Map;

import org.richfaces.model.TreeNode;

public class MyRFTreeNode implements TreeNode, Serializable {

    private Picture data;

    private List<Object> keyList = new ArrayList<Object>();

    private Map<Object, TreeNode> children = new HashMap<Object, TreeNode>();

    private MyRFTreeNode parent;

    public MyRFTreeNode() {

        this.data = new Picture("Root", null);

    }

    public MyRFTreeNode(Picture data) {

        this.data = data;

    }

    @Override

    public TreeNode getChild(Object o) {

        return children.get(o);

    }

    @Override

    public int indexOf(Object o) {

        return keyList.indexOf(o);

    }

    @Override

    public Iterator<Object> getChildrenKeysIterator() {

        return keyList.iterator();

    }

    @Override

    public boolean isLeaf() {

        return false;

    }

    @Override

    public void addChild(Object o, TreeNode tn) {

        children.put(o, tn);

        keyList.add(o);

        ((MyRFTreeNode) tn).setParent(this);

    }

    @Override

    public void insertChild(int i, Object o, TreeNode tn) {

        addChild(o, tn);

    }

    @Override

    public void removeChild(Object o) {

        children.remove(o);

        keyList.remove(o);

    }

    public void setParent(MyRFTreeNode parent) {

        this.parent = parent;

    }

    public Picture getData() {

        return data;

    }

    public MyRFTreeNode getParent() {

        return parent;

    }

}

The managed bean:

package beans;

import entities.Picture;

import javax.faces.bean.ManagedBean;

import javax.faces.bean.RequestScoped;

import model.MyRFTreeNode;

@ManagedBean

@RequestScoped

public class TreeBeanRFTreeNode {

    private MyRFTreeNode root;

    public TreeBeanRFTreeNode() {

        root = new MyRFTreeNode();

        MyRFTreeNode node1 = new MyRFTreeNode(new Picture("picture1", "Description1"));

        MyRFTreeNode node2 = new MyRFTreeNode(new Picture("picture2", "Description2"));

        MyRFTreeNode node3 = new MyRFTreeNode(new Picture("picture3", "Description3"));

        root.addChild(1, node1);

        root.addChild(2, node2);

        root.addChild(3, node3);

        MyRFTreeNode node11 = new MyRFTreeNode(new Picture("picture11", "Description11"));

        MyRFTreeNode node12 = new MyRFTreeNode(new Picture("picture12", "Description12"));

        MyRFTreeNode node13 = new MyRFTreeNode(new Picture("picture13", "Description13"));

        node1.addChild(11, node11);

        node1.addChild(12, node12);

        node1.addChild(13, node13);

    }

    public MyRFTreeNode getRoot() {

        return root;

    }

}

Only implementing javax.swing.tree.TreeNode works for me (for now). I'll not paste the code because the post will be too long

Waiting for your answer.

Hi,

Are you using EAR or WAR?

[codo]

Hello,

I'm using WAR.

Btw in my managed bean I changed the type of "root" property from MyRFTreeNode to List<MyRFTreeNode> (I saw in your example that you are using List) and now the output is different:

[nbelaevski]

Looks like a bug - thanks for reporting! I've reopened RF-9718 to get this fixed.

[codo]

Hello,

I saw that bug 9718 is marked as resolved so I downloaded the nightly build from yesterday(10.3.2011) and tried my examples. The example which is using org.richfaces.model.TreeNode works now, but the other, using org.richfaces.model.TreeDataModel, doesn't work. It throws the same exception.

[nbelaevski]

Yup, that's what I missed to add - sorry. Reopened the issue and will add support now.

[nbelaevski]

Done.

[codo]

Super! Thank you!
