---------------------------------
Resolution: Duplicate
> More javascript events for zones
> --------------------------------
>
> Key: TAP5-1525
> URL: https://issues.apache.org/jira/browse/TAP5-1525
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.2.0
> Reporter: Joe Klecko
>
> It seems that time and time again for each T5 project (6 out of 7 so far) I
> find I need to override tapesty.js methods to add additional support for
> zones. Currently there is only 1 event fired from a zone
> (Tapestry.ZONE_UPDATED_EVENT), I'd like to suggest/request there be at least
> 4 events total (3 new ones):
> 1) ZONE_BEFORE_AJAX_REQUEST_EVENT: This would be fired before the ajax
> request is sent to the server. Listeners should be able to cancel the ajax
> request (similiar to the way tapestry allows a form submission to be
> canceled). Access to the "options" object to be passed to
> "Tapestry.ajaxRequest" should be accessible(read/write) from the event's memo
> property (or where ever, just accessible).
> 2) ZONE_BEFORE_UPDATE_EVENT: This would be fired after the ajax request
> returns and just before the zone is updated via the processReply() method.
> Again, listeners should be able to cancel the update. Access to the "options"
> object passed to "Tapestry.ajaxRequest" should be accessible from the event's
> memo property (or where ever, just accessible).
> 3) ZONE_UPDATED_EVENT: already and is listed here for completeness.
> 4) ZONE_AJAX_REQUEST_ERROR_EVENT: This would be fired if the ajax request
> errored out for the zone. (includes error data)
