Zabbix 1.8.1, problem creating triggers

[stefstef]

I've run into two problems while trying to create triggers in Zabbix 1.8.1 and I'm wondering if anyone has found a workaround for them.

First is I cannot get the expression editor to assemble trigger conditions. When I've created and added the first condition and try to add another (using either the AND or OR keys), the editor always replaces the first condition and displays the following error:
* Undefined index: &{astand:ARB-S1.avg(1800)}>8[/home/zabbix/public_html/include/triggers.inc.php:3093]

If I enter the expression in the simple editor and toggle to the other one, the expression tree displays correctly.

My second problem (and the more serious) is I'm unable to save my triggers. Whenever I try to save I get the following error:
An item key must be used in trigger expression

The ARB-S1 item used in my examples above is in use and updates frequently, so I'm pretty sure it's a valid item key.

Can anyone point me in the right direction on how to solve this?

Kind regards
Stebbi

I have the same issue after upgrading,

I´m also searching for a solution.

I have created a new trigger with another item, that seems
to work. And I have update some other triggers.


But I´m not able to update this triggers.

This is one trigger I was not able to update.
{DESWT009:Port 1 in bps.min(#2)}>0.75*{DESWT009:Port 1 Speed.max(#2)}

I can confirm this only happens with custom items I've created. I can create triggers using default items. Could this be a problem with character sets as I'm using Icelandic letters in my item names?
