also fails for :

{A Test Host 2:run[cat something | cut -d\" -f1].last(0)}

=0&

{A Test Host 2:b,+.last(0)}

=0

Still reproducible in r25483.

Most of the item keys used in the expressions are invalid in 2.0. The others are saved correctly.

(1) Item with the key "a[,`~!@#$%^&*()-_=+,"[]",{}|;:","",<.>/?]" fails when testing a trigger expression in the expression constructor, even when the item exists.

<pavels> It turned out to be a simple decoding error. RESOLVED.

<Vedmak> When try to test trigger with this item some errors are shown.

<pavels> RESOLVED.

<Vedmak> CLOSED
