interesting - group selection actually has "all groups" option, which probably should be the default as well - but choosing that results in a different error message :

No host group ID provided for screen element. [CScreenItem.create -> CScreenItem.checkInput]

<pavels> Same thing, only the error message in the trunk differs from 1.8.

actually, there might be a problem with displaying as well - at least in trunk i get :

Illegal offset type in isset or empty [include/triggers.inc.php:1540]
Illegal offset type in isset or empty [include/triggers.inc.php:1655]

<pavels> Can't reproduce it, could you give some more details? May be a screenshot?

<richlv> for the record, this happened when an element with 'all groups' or no groups selected was already added to a screen (thus the original bug must be fixed to see this one)

<pavels> Wait, the original issue only affects the "Trigger info" screen items, while the one you describe affects the "Trigger overview" items. They're not connected. Or am I missing something?

<richlv> oh, that is possible - i had a screen with multiple elements and assumed errors come from triggers info. should a new issue be opened or can both problems be solved in here ?

<pavels> It's a trunk-only problem, so I've opened a new issue for it ZBX-4630.

<richlv> thanks, CLOSED

Fix for 1.8 is available in /branches/dev/ZBX-4593.

Seems triggers info group is missing validation now.

<pavels> Right, fixed. RESOLVED.

Merged to 1.8 r25360 and trunk r25361.

CLOSED.
