Hi small doubt. In tapestry 3.0.3 we cannot use binding with value in page
specification that is .page file while writing component element. We have to
use binding with expression and staticbinding with value. Is it changed in
tapestry 4.0.
Tapestry 3.0.3
<component id="xxx" type="xx">
<binding name="www" expression="uuu"/>
</component>
is this changed in tapestry 4.0

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

elementId) {

document.progUpdater = new
Ajax.PeriodicalUpdater('progress', linkString, {asynchronous:true,

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.
