Well I am using tapestry4.0-4beta version.
Let me give the code details to you,

Can you paste the complete page specification you are using to embed the
progressbar? It looks somehow mis-configured to me. Or, you could possibly
be using the wrong version of tapestry. The current progressbar requires
tapestry4 at a minnimum.
