TreeNode is abstract, cannot be instantiated...

[Jim Rocard]

Hello, I am attempting to implement a basic treenode model and eventually would like to implement the tree table, however Netbeans throws an error "org.primefaces.model.TreeNode is abstract; cannot be instantiated" when the following code is called:

Code: Select all

public void setRootNode(){
        root = new DefaultTreeNode("root", null);
        TreeNode directoryNode;
        Directory d = new Directory();
        TreeNode documents = new DefaultTreeNode("documents", root);
        List<Directory> dirs = directCont.getItemsByOwner();
        Iterator it = dirs.iterator();
        while (it.hasNext()){
             d = (Directory)it.next();
             directoryNode = new TreeNode(d);          
        }

I feel like I'm doing something wrong, but I have been staring at it for a while and can't seem to figure out what it is.

Thanks in advance!!

"As for TreeNode, you need to use DefaultTreeNode class now."

Answered my own question. Thanks.

No need to stare... Just look at the labs examples...
