Fields / Form validation
Tapestry includes a number of form-related components. Tapestry components are
responsible for reading properties when a page is rendered, to supply default values,
and writing properties when the form is submitted; it is never necesssary to write
code to directly read HTTP parameters.
Input field components can perform validations on the client-side, triggered
by the user submitting the form. The checkbox above enables or disables
this feature. Input is always rechecked on the server-side (in case the client
doesn't support JavaScript).
