NOT NULL in DSL rule trigger

Hey Rich,
do you know if this answer you provided is is still true?
I tried this one

Member of gAlarms changed to !NULL

but does not work. Just wanted to double check.

No, you cannot do any sort of comparisons, boolean operations, or mathematical operations in a rule’s trigger.

To do a test like that you’d use a rule condition in the UI or an if statement in the body of your rule in a text file.
