Tapestry 5.1 has this lazy loading included as component: check the
ProgressiveDisplay component.

I made a simple "LazyZone" component which ajax loads the zone after the
page load. Should be simple enough to add a timer to it. You provide a
block as a parameter to the component...
LazyZone.java
-------------
@IncludeJavaScriptLibrary("lazyZone.js")
public class LazyZone extends Zone {
@Parameter
private Block content;
@Inject
private ComponentResources resources;
@Environmental
private RenderSupport renderSupport;
@AfterRender
void renderCallback() {
// generate a link which when used client side will
invoke event handler below
Link link = resources.createEventLink("provideContent");
// get tapestry to initialise us client side
renderSupport.addInit("lazyZoneLoad", getClientId(),
link.toURI());
}
public Object onProvideContent() {
// return the block which was passed as parameter,
tapestry
// will render it for us
return content;
}
}
lazyZone.js
-----------
Tapestry.Initializer.lazyZoneLoad = function(element, url) {
$T(element).zoneManager.updateFromURL(url);
}

Subject: automatic zone update
I'm trying to create a zone which automatically updates itself after
some time. Any suggestions?
