Hi guys,
has contrib:treeView been tested with tapestry4-beta4?
I'm getting a weird NumberFormat exception using a basic example found
at https://tapestrywebcomponentexamples.dev.java.net
this is the stack trace...

Java Class:
public ITreeModel getTreeModel() {
if (_treeModel == null) {
TreeNode root = new StringTreeNode("Root");
TreeNode lubrificanti = new StringTreeNode("Lubrificanti");
TreeNode trasmissioni = new StringTreeNode("Trasmissioni");
TreeNode grassi = new StringTreeNode("Grassi");
TreeNode motore = new StringTreeNode("Motore");
lubrificanti.insert(trasmissioni);
lubrificanti.insert(grassi);
lubrificanti.insert(motore);
root.insert(lubrificanti);
// Wrap the root node in a SimpleTreeDataModel
_treeDataModel = new SimpleTreeDataModel(root);
// Wrap the SimpleTreeDataModel in a SimpleTreeModel
_treeModel = new SimpleTreeModel(_treeDataModel);
}
return _treeModel;
}
public ITreeStateListener getTreeStateListener(){
return this;
}
