Environment: windows xp using Internet Explorer 7 (specific version

Reporter: Frederick Gaetos
Hi! Im just new here and was wondering if anyone could help me out with an
exception that I wanted to replicate.
(using tapestry version 3)
(environment: windows xp)
(browser: internet explorer 7 [specific version 7.0.5730]
anyway, I have 3 concerns.
1.) How can I replicate the "BindingException"
org.apache.tapestry.BindingException: unable to Unable to update expression.
2.)what is the real problem why this happens? (what is the cause).
3.)How can I eliminate it...
(been searching google 'bout this concern and still I haven't got any clue,
hint and of course an answer to this).
(P.S. please give me notice if I had post this concern in the wrong forum).
here's the exception...
