Using Tree component in Tapestry

[Samuel Cheung <sy...@gmail.com>]

Hi,

i am using the Tapestry Tree component from here: 
https://tapestrywebcomponentexamples.dev.java.net/

I create my own implementation of ITreeNode and add the implementation 
of the interface methods.  I want to build the tree nodes dynamically 
(i.e. the TreeNode will add its children when user clicks it and if it 
has children).

I get the expand works. But sometimes, when I click on the leaf node, I 
get this "The document has no data from Mozilla Firefox" error dialog. 
And once I get one "document has no data dialog",  I keep getting that 
dialog whenever I click.

does someone has an idea what did I miss? or how can I trouble shoot this?

Thank you.
Sam
