[jboss-user] [JBoss Seam] - Re: Trinidad Tree + Seam Action Bean

[petemuir]

I have this working (for a treetable at least). I used a facelets function:

<tr:treeTable value="#{my:asRootedTree(value)}">...


  | public class Utils {
  | private static TreeModel asTree(Object tree, boolean createRoot) {
  |    if (createRoot && tree instanceof Collection) {
  |       TreeRoot root = new TreeRoot((Collection) tree);
  |       return new ChildPropertyTreeModel(root, "children");
  |    } else {
  |       return new ChildPropertyTreeModel(tree, "children");
  |    }
  | }
  | 	
  | public static TreeModel asTree(Object root) {
  |    return asTree(root, false);
  | }
  | 	
  | public static TreeModel asRootedTree(Object root) {
  |    return asTree(root, true);
  | }
  | 	
  | public static class TreeRoot {
  | 		
  |    private Collection<?> children;
  | 
  |    public TreeRoot(Collection<?> children) {
  |       this.children = children;
  |    }
  | 		
  |    public Collection<?> getChildren() {
  |       return children;
  |    }
  | 		
  |    public String getType() {
  |       return "root";
  |    }
  | }
  | }

N.B. These method can create a singly rooted tree from a list (with a dummy root) or take a single object as the root node.

and wired it up using my.taglib.xml.  value can now be a Seam outjected list.
