the new trigger editor incorrectly reverses elements. while this is not significant if the expression is like A&B or A|B, the attached screenshot shows the following expression :

{Another Host:net.tcp.service[ssh].last(0)}

=0 &

{A Test Host:net.tcp.service[ssh].last(0)}

=0 |

{A Test Host:grpavg["Linux servers","system.cpu.load","last","0"].last(0)}

=0

which becomes :

{A Test Host:grpavg["Linux servers","system.cpu.load","last","0"].last(0)}

=0 &

{A Test Host:net.tcp.service[ssh].last(0)}

=0 |

{Another Host:net.tcp.service[ssh].last(0)}

=0

thus the trigger logic is completely broken
