Howard, et. al.,
I am not quite sure how to request this.  In Tapestry 3.0x, I don't use the Tapestry Validation.
 I create what we call a connection.  At times, I need to, programmatically, check the connection
for errors.  I do this by asking all of the parts of a component if they have any errors.
 The problem with validators has been that they only get called by Tapestry.  How could I
tell Tapestry to walk all of my pages/components and validate them?  Which brings up the issue
of they don't exist except in pools until they are displayed.  So, the only way to "activate"
them is to display every page and have it rendered.

And that is the intention!

Also, the ability to just ask the Form to record errors simplifies the
code signficantly. You almost never need to think about the
ValidationTracker object (which is a persistent field of the Form
