Generating a htmlTree dynamically

[rchiarinelli.rchiarinelli.gmail.com]

Hi All,

   I'm developing a JSP, using RichFaces and Seam, which contains a htmlTree that is generated dynamically. But, my page doesn't show the htmlTree. Here is the snippet from JSP and the ManagedBean:

JSP:
.
.
.
        <h:form id="treeMenuForm">
                <rich:tree id="tree" binding="#{htmlTree}"/>
        </h:form>
.
.
.

ManagedBean:

    @Out(required = false)
    private HtmlTree htmlTree;

    @Begin(join = true)
    @Factory(value = "htmlTree")
    public HtmlTree getHtmlTree() throws ValidationException {
        if (this.htmlTree == null) {
            //HtmlTree
            Application application = FacesContext.getCurrentInstance().getApplication();
            this.htmlTree = (HtmlTree) application.createComponent(HtmlTree.COMPONENT_TYPE);
            htmlTree.setStyle("width:300px");
            htmlTree.setRendered(true);
            htmlTree.setIcon("/image/Treeview/Treeview_folder_opened_A.gif");
            htmlTree.setIconCollapsed("/image/Treeview/Treeview_plus_last_node.gif");
            htmlTree.setIconExpanded("/image/Treeview/Treeview_minus_last_node.gif");
            htmlTree.setIconLeaf("/image/Treeview/Treeview_page_A.gif");
            htmlTree.setSwitchType("server");
            htmlTree.setAdviseNodeOpened(application.createMethodBinding(
                     "#{mainViewAction.expanded}", new Class[0]));
            htmlTree.setChangeExpandListener(application.createMethodBinding(
                    "#{mainViewAction.changeExpandListener}", new Class[0]));
            htmlTree.getChildren().add(this.buildNodes(this.treeMenu));

        }
        return this.htmlTree;
    }

    /**
     *
     * @param nodes
     * @return
     */
    private HtmlTreeNode buildNodes(GBNode[] nodes) {
        Application application = FacesContext.getCurrentInstance().getApplication();
        UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();
        HtmlTreeNode htmlTreeNode = null;
        HtmlGraphicImage image = null;
        HtmlOutputText text = null;
        for (int cont = 0; cont < nodes.length; cont++) {
            GBNode item = nodes[cont];
            htmlTreeNode = (HtmlTreeNode) application.createComponent(HtmlTreeNode.COMPONENT_TYPE);
            htmlTreeNode = new HtmlTreeNode();           
            htmlTreeNode.setId(viewRoot.createUniqueId());
            htmlTreeNode.setRendered(true);
//            Imagem do nó
            image = (HtmlGraphicImage) application.createComponent(HtmlGraphicImage.COMPONENT_TYPE);
            image = new HtmlGraphicImage();           
            image.setId(viewRoot.createUniqueId());
            image.setHeight("18");
            image.setWidth("15");
            image.setStyleClass("textCurrentTreeview");
            htmlTreeNode.getFacets().put("icon", image);
            //Texto do nó
            text = (HtmlOutputText)
                   application.createComponent(HtmlOutputText.COMPONENT_TYPE);
            text = new HtmlOutputText();           
            text.setId(viewRoot.createUniqueId());
            text.setValue(item.getText());
            text.setStyleClass("textCurrentTreeview");
            htmlTreeNode.getChildren().add(text);
        }
        return htmlTreeNode;
    }


Can anyone help me?

Sorry people. The correct style for the post:

JSP:

<h:form id=treeMenuForm>

<rich:tree id=tree binding=#{htmlTree}/> 

</h:form>

ManagedBean:

@Out(required = false) private HtmlTree htmlTree; 

@Begin(join = true) 
@Factory(value = "htmlTree") 
public HtmlTree getHtmlTree() throws ValidationException { 
            //HtmlTree
            Application application = FacesContext.getCurrentInstance().getApplication();
            UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();            
            this.htmlTree = (HtmlTree) application.createComponent(HtmlTree.COMPONENT_TYPE);
            this.htmlTree.setId(viewRoot.createUniqueId());
            this.htmlTree.setStyle("width:400px");
            this.htmlTree.setRendered(true);
            this.htmlTree.setIcon("/image/Treeview/Treeview_folder_opened_A.gif");
            this.htmlTree.setIconCollapsed("/image/Treeview/Treeview_plus_last_node.gif");
            this.htmlTree.setIconExpanded("/image/Treeview/Treeview_minus_last_node.gif");
            this.htmlTree.setIconLeaf("/image/Treeview/Treeview_page_A.gif");
            this.htmlTree.setSwitchType("server");
            this.htmlTree.setAdviseNodeOpened(application.createMethodBinding("#{mainViewAction.expanded}", new Class[0]));
            this.htmlTree.setChangeExpandListener(application.createMethodBinding("#{mainViewAction.changeExpandListener}", new Class[0]));
            this.htmlTree.getChildren().add(this.buildNodes(this.treeMenu));
}

    private HtmlTreeNode buildNodes(GBNode[] nodes) {
        Application application = FacesContext.getCurrentInstance().getApplication();
        UIViewRoot viewRoot = FacesContext.getCurrentInstance().getViewRoot();
        HtmlTreeNode htmlTreeNode = null;
        HtmlGraphicImage image = null;
        HtmlOutputText text = null;
        for (int cont = 0; cont < nodes.length; cont++) {
            GBNode item = nodes[cont];
            htmlTreeNode = (HtmlTreeNode) application.createComponent(HtmlTreeNode.COMPONENT_TYPE);
            htmlTreeNode.setId(viewRoot.createUniqueId());
            htmlTreeNode.setRendered(true);
//            Imagem do nó
            image = (HtmlGraphicImage) application.createComponent(HtmlGraphicImage.COMPONENT_TYPE);
            image.setId(viewRoot.createUniqueId());
            image.setHeight("18");
            image.setWidth("15");
            image.setStyleClass("textCurrentTreeview");
            htmlTreeNode.getFacets().put("icon", image);
            //Texto do nó
            text = (HtmlOutputText) application.createComponent(HtmlOutputText.COMPONENT_TYPE);
            text.setId(viewRoot.createUniqueId());
            text.setValue(item.getText());
            text.setStyleClass("textCurrentTreeview");
            htmlTreeNode.getChildren().add(text);
            if (item.getChildren()!=null && item.getChildren().length > 0) {
                htmlTreeNode.getChildren().add(this.buildNodes(item.getChildren()));
            }
        }
        return htmlTreeNode;
    }
