RF 4: Example of using org.richfaces.model.TreeDataModel?

codo Mar 26, 2011 5:43 PM

Hello,

I am trying to implement the new org.richfaces.model.TreeDataModel interface to manipulate tree data. I have no success in doing that. I understand that my implementation class has to extend org.ajax4jsf.model.ExtendedDataModel to work properly. I overrode all methods that I'm supposed to override. The result of my attempts are properly rendered tree, but when I try to expand a node exceptions are thrown. I'll be greatfull if someone give me an example how to use this new model properly.

Greetings

Hello,

Sorry for my late response. I'll show you part of my code.

My model implementation:

public class MyRFTreeDataModel extends ExtendedDataModel<Picture>
        implements TreeDataModel<Picture>, Serializable {

    private Picture data;
    private Object rowKey;
    private List<TreeDataModelTuple> children = new ArrayList<TreeDataModelTuple>();
    private MyRFTreeDataModel parent;

    public MyRFTreeDataModel() {
        this.data = new Picture("Root", null);
    }

    public MyRFTreeDataModel(Object rowKey, Picture data) {
        this.rowKey = rowKey;
        this.data = data;
    }

    @Override
    public Object getRowKey() {
        return rowKey;
    }

    @Override
    public void setRowKey(Object o) {
        this.rowKey = o;
    }

    @Override
    public boolean isDataAvailable() {
        if (data != null) {
            return true;
        }
        return false;
    }

    @Override
    public boolean isLeaf() {
        return false;
    }

    @Override
    public Picture getData() {
        return data;
    }

    @Override
    public Iterator<TreeDataModelTuple> children() {
        return children.iterator();
    }

    @Override
    public Object getParentRowKey(Object o) {
        return parent.getRowKey();
    }

    @Override
    public Object getWrappedData() {
        return data;
    }

    @Override
    public void setWrappedData(Object o) {
        data = (Picture) o;
    }

    @Override
    public TreeDataModelTuple createSnapshot() {
        return new TreeDataModelTuple(rowKey, data);
    }

    @Override
    public void restoreFromSnapshot(TreeDataModelTuple tdmt) {
        rowKey = tdmt.getRowKey();
        data = (Picture) tdmt.getData();
    }

    @Override
    public Converter getRowKeyConverter() {
        return null;
    }

    public void addChild(TreeDataModel<Picture> child) {
        children.add(new TreeDataModelTuple(child.getRowKey(), child.getData()));
    }

    @Override
    public void walk(FacesContext fc, DataVisitor dv, Range range, Object o) {
        dv.process(fc, rowKey, o);
    }

    @Override
    public boolean isRowAvailable() {
        return true;
    }

    @Override
    public int getRowCount() {
        return children.size();
    }

    @Override
    public Picture getRowData() {
        return data;
    }

    @Override
    public int getRowIndex() {
        return 0;
    }

    @Override
    public void setRowIndex(int rowIndex) {
    }
}

My bean:

@ManagedBean
@RequestScoped
public class TreeBeanRFTreeDataModel {

    private MyRFTreeDataModel root;

    public TreeBeanRFTreeDataModel() {
        root = new MyRFTreeDataModel();
        MyRFTreeDataModel node1 = new MyRFTreeDataModel(1, new Picture("picture1", "Description1"));
        MyRFTreeDataModel node2 = new MyRFTreeDataModel(2, new Picture("picture2", "Description2"));
        MyRFTreeDataModel node3 = new MyRFTreeDataModel(3, new Picture("picture3", "Description3"));

        root.addChild(node1);
        root.addChild(node2);
        root.addChild(node3);

        MyRFTreeDataModel node11 = new MyRFTreeDataModel(11, new Picture("picture11", "Description11"));
        MyRFTreeDataModel node12 = new MyRFTreeDataModel(12, new Picture("picture12", "Description12"));
        MyRFTreeDataModel node13 = new MyRFTreeDataModel(13, new Picture("picture13", "Description13"));

        node1.addChild(node11);
        node1.addChild(node12);
        node1.addChild(node13);
    }

    public MyRFTreeDataModel getRoot() {
        return root;
    }
}

My xhtml:

                <h:form id="form_main_tree">
                    <rich:tree value="#{treeBeanRFTreeDataModel.root}" var="item">
                        <rich:treeNode>
                                <h:outputText value="#{item.name}"/>
                        </rich:treeNode>
                    </rich:tree>
                </h:form>

And the exception (it is thrown when I try to expand a node):

4. RF 4: Example of using org.richfaces.model.TreeDataModel?

You are implementing children() and walk(...) methods incorrectly - see how they are implemented in built-in models. Also you should have one model per component, while in your example each node has its own model.
