I've noticed that from 1.92 array filters are managed with
Expression Manager.
In particular I've noticed, tell me if I'm wrong, that
Expression Manager use filter qCode to generate a !is_empty(qCode_sq)-like condition for each subquestion sq.
It would be very cool to give the possibility to use a relevance-like equation in the filter field in order to extend the possibility of array filter.
Here a scheme to explain better:
Q1: question
A1 A2 A3
SQ1
SQ2
SQ3
Q2: question2
A4 A5 A6
SQ1
SQ2
SQ3
Q2 filter_equation: (Q1==“A2” || Q1==“A3”)
this equation would generate (Q1_sq == “A2” || Q1_sq == “A3”) for each subquestion sq showing in the question Q2 only the subquestions that have answer A2 or A3 in question Q1
