This example is based on the <em>Filter CRUD</em> example and adds AJAX functionality with Tapestry's Zone component.<br/>

Highlight zone updates?
<input t:type="checkbox" t:id="highlightZoneUpdates" value="highlightZoneUpdates" onclick="this.form.submit()"/>
This shows you which zones are updated by the Ajax response.
