How do I get the size/length of a fixed_array_of_string? In a code template I need to know if the size is greater than 0. I have tried various combinations of length and size properties. My "appeals on this line" is an array of string.
_line.appealsOnThisLine.size > 0 = true
(keep getting some variation of size/length/method not a property of fixed_array_of_string)
