Hello Murray,
One of the basic classes in the AJAX support is ResponseBuilder
http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/services/ResponseBuilder.html
There you can call a method updateComponent(String) with id of the
component you want to update. That's all you don't need to use
updateComponents parameter.

Hi all
I hunted for ages and haven't been able to find any simple examples of how to
use the Ajax features of Tapestry 4.1. Sorry guys, it's just not obvious from
the documentation how it works.
You would think a basic @DirectLink with updateComponents and async=true would
do it - nah, didn't work for me:
<a jwcid="@DirectLink" listener="listener:changeTab"
parameters="2"
updateComponents="orderarea"
async='true'
class="tab">
Text</a>
public void changeTab(IRequestCycle cycle) {
Object[] parameters = cycle.getListenerParameters();
Integer iix = (Integer) parameters[0];
setCurrentTab(iix);
System.err.println("Set tab to " + iix.intValue());
}
The page displays but when I click the above link it disappears and I see part
of an exception output display.
If somebody can point me at a simple Ajax enabled app using Tap 4.1 would
probably help me greatly.
Cheers
