unable to view primefaces tree
I am new to JSF so this is my first project. My IDE is netbeans 7.0.1, Mojarra 2.1.1 and primefaces 2.2.1
I used the tree example via http://www.primefaces.org/showcase/ui/tree.jsf While I manage to use other faclets from prime (for example p:button) the tree is not working for me(blank screen) Can someone can please explained me what did I do wrong ?
Thanks

TreeNode node100 = new DefaultTreeNode("Node 1.0.0",开发者_运维技巧 node10);
}
public TreeNode getRoot() {
return root;
}
}
I think it's because you don't have @ManagedBean annotation in your TreeBean class
加载中,请稍侯......
