I'm trying to make a simple radio button validate: we just have to know if the user has selected something from the group. I keep trying to set the JQL query for the validator to
%{17900} != null
and define the validation as "current issue belongs to output of the query"
But when set like this, even if a radio button/option is selected, the validation fails, and the error message still displays. What is the criteria, if not null?
