I found the solution. The event I was looking for is "events.zone.refresh". See where it is triggered in module "t5/core/zone".
@Lenny Primak Thanx for pointing out the T5.4 branch of Flowlogix library, I didn't notice it at first. Your mixin "ZoneLoadingSpinner" is exactly what I need, but there is one bug you may want to fix: in file spinner-zone-overlay.js on line 35 you need to change "events.zone.willUpdate" to "events.zone.refresh". With this fix, the mixin adds a spinner overlay for all of these cases: - Zone update triggered by actionLink / eventLink - Zone update triggered by form submit - Grid inplace update after click on paging link - Grid inplace update after click on sorting link - (I didn't test other cases) Thanx for sharing your code :) Martin On Thu, Mar 20, 2014 at 1:28 PM, Martin Nagl <mn...@mtbiker.sk> wrote: > In T5.4, the event "t5:zone:did-update" fires only after zone has been > updated, which is too late to add overlay to the zone. > > I need to add the zone overlay just after user clicks on a ajax-enabled > EventLink / ActionLink (including paging and sorting links in Grid), or > just after user submits an ajax-enabled Form - before server starts > processing the request (which may take a few seconds). > > In T5.3, one could attach to Tapestry.TRIGGER_ZONE_UPDATE_EVENT, which was > being fired before request was sent to server, so it was suitable for this > case.
