If you use a zone, you can call
var zoneObject=Tapestry.findZoneManagerForZone('<DOM id of zone>');
zoneObject.updateFromURL('<url>', {});
in JS.
When generating the JS code in your TML, you can generate the correct
URL by having something like the following in your page / component class:
@Inject ComponentResources resources;
...
final String url =
resources.createEventLink("getGroupsOnLocation").toString();
and then put that url into your JS code via the TML. If you have an
event context, you can of course add that to the event link.
At least it worked for me that way.
Hope that helps
