You are probably running into the fact that Tapestry rewrites your page/component classes so that there is only one instance of the class used across all requests. To do this all of the property accesses are intercepted and replaced with ThreadLocal values. When you are in development mode tapestry shadows the values in the actual class itself so that you can see them in the debugger.
Check out this fixed issue for more details https://issues.apache.org/jira/browse/TAP5-1208 Have you considered using a Mixin? http://tapestry.apache.org/component-mixins.html Or possibly you could write your own class transformer : http://tawus.wordpress.com/2011/04/21/plastic-property/ Josh On Aug 1, 2012 12:22 AM, "mem" <memcacher+tapes...@gmail.com> wrote: > Hello, > > hope this Thread is still alive. > I've used a similar approach to figure out if the label is attached to a > field which renders a required field.
