The problem here:

                        if($trigger['event_count']){
                                $to_ack = new CCol(array(new CLink(_('Acknowledge'), 'acknow.php?triggers[]='.$trigger['triggerid'].'&backurl='.$page['file'], 'on'), ' ('.$trigger['event_count'].')'));
                        }
                        else{
                                $to_ack = new CCol(_('Acknowledged'), 'off');
                        }

We think all events already acknowledged if $trigger['event_count'] non-exist or equal 0. But if a trigger has not any events we can not say what they has been acknowledged!

but if there are no events, what should we display then ?

old fired triggers can be without events (small keep time of events for records or partitioning).

We decided to show 'No events' string for such triggers.

dev branch: svn://svn.zabbix.com/branches/dev/ZBX-5579

(1) If I select a host without triggers on the trigger status page, I receive an error:

Undefined variable: triggerIdsWithoutUnackEvents [tr_status.php:400]

(2) Can you please change 'noEvents' to 'hasEvents'. I, personally, think it's more intuitive that way.

TESTED.

Fixed in 2.0.4rc1 r30536, pre-2.1.0 r30537.

(3) Triggers in an "Acknowledged" status if trigger has only unknown or not significant events. We can't acknowledge these events.

(4) That change should be documented on http://www.zabbix.com/documentation/2.0/manual/web_interface/frontend_sections/monitoring/triggers

(5) Error if filter events by "Show unknown events":
Undefined index: 10087 [events.php:671]
Undefined index: [events.php:720]
Argument 1 passed to hostMenuData() must be an array, null given, called in /home/zabbix/www/testing-ZBX-5579/frontends/php/events.php on line 721 and defined [include/hosts.inc.php:1312]

Vedmak seems it caused by event from templated trigger
Eduards CLOSED, seems my database is corrupted

(6) Please pass $_REQUEST['showUnknown'] directly as option to Event API

Vedmak left as it is, as discussed.
Eduards CLOSED

Tested!

Fixed in 2.0.4rc1 r31036, pre-2.1.0 r31037.
