(1) There is problem with multibyte string in trigger expressions. Expression

{my replace template:log["āšē"].last(0)}

=0 gives "Incorrect trigger expression format" error while

{my replace template:log["ase"].last(0)}

=0 does not

TESTED

Comment by Alexey Fukalov [ 2012 Oct 04 ]

Fixed in 2.0.4rc1 r30533, pre-2.1.0 r30534.

Comment by Alexander Vladishev [ 2012 Nov 05 ]

Stay reproducible in latest 2.0 r31248.

Steps to reproduce:

  • add two items:
    • item
    • item[ {host:item.last(0)}
  • add trigger with expression 
    {host:item.last(0)}=0 | {host:item[{host:item.last(0)}].last(0)}=0
  • we have incorrect trigger expression in the DB: 
    {13123}=0 | {host:item[{13123}].last(0)}=0
Comment by Alexander Vladishev [ 2012 Nov 23 ]

Fixed in pre-1.8.16 r31955, pre-2.0.4 r31650 and pre-2.1.0 r31649.
