Building the HtmlTree at runtime
Hi All, I'm developing in an HtmlTree, using RichFaces and Seam, which 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 {
//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;
}
Any ideas?
tks
