Can't use {TRIGGER.VALUE} in trigger - Zabbix 1.6.6

[whowd]

Anytime I try to use {TRIGGER.VALUE} in a trigger I receive the following message:

An item key must be used in trigger expression

Here's a new a trigger I'm trying to setup:

(({Template_Website:http,80.sum(#3)}=0)&{TRIGGER.VALUE}=0)|(({TRIGGER.VALUE}=1)&({Template_Website:http,80.sum(#6)}#6))

I will also receive this error if I go and try to edit an existing trigger that I had defined with a {TRIGGER.VALUE} entry. I upgraded to 1.6.6 from 1.6.2 a few weeks ago.

Any ideas?

Just guessing here, but what if you put extra brackets around the Trigger.Value expression? ({TRIGGER.VALUE}=0))

(({Template_Website:http,80.sum(#3)}=0)&({TRIGGER. VALUE}=0))|etc...

Even with the extra brackets, it returns the same message

Same problem here, doesn't work with the following trigger-expression:

({TRIGGER.VALUE}=0&{SensGroup_TempRZ:sensor_temperature.last(0)}>25) | 
({TRIGGER.VALUE}=1&{SensGroup_TempRZ:sensor_temperature.last(0)}>22)

This also doesn't work with double brackets...

Always the error "An item key must be used in trigger expression".

Is this a bug in expression-parsing on the "Save"-Button in the web gui? Existing hysteresis-expressions which were created in earlier zabbix-versions are running fine as long as I don't want to change them via gui...

I applied the fix in the bug details, changing the lines at 625/626 to the following:

                        if($arr[ZBX_EXPRESSION_MACRO_ID]) {
                                if (!isset($ZBX_TR_EXPR_ALLOWED_MACROS[$arr[ZBX_EXPRESSION_MACRO_ID]]) ){
                                        error('Unknown macro ['.$arr[ZBX_EXPRESSION_MACRO_ID].']');
                                        return false;
                                }
                        }

I could then add triggers with {TRIGGER.VALUE}
