Summary13531: No recorded responses for a displayed question

I have a survey with a numeric input type question (Q42) followed by an Array (1-5) -- Q43.

The array question (Q43) had a condition on it to only display if :

((Q42.NAOK > " "))

When testing this survey, if I left Q42 blank, then Q43 was hidden, and if I entered a value, Q43 was shown, as expected.

I understand in restrospect that I should have used !is_empty(Q42) instead ... however my testing showed that Q43 was displayed.

I activated the survey, and after collecting data from 10,000+ respondents, discovered that in all cases responses Q43 was blank. Q43 wasn't set to mandatory, but with the number of respondents, it seems unlikely that anyone who entered a value for Q42 would skip Q43.

My survey format was set to "Group by Group"... and Q43 appeared but ....

... I did discover that I run my survey with format "question by question" q43 is NEVER displayed (and so -> no answers). In format "group by group" q43 is displayed, but handled as if not displayed -> no answers.

TagsNo tags attached.

We add some '' in test for expression :

Strange this was not fixed after testing and improve system :/

This again? I didn't get the time to fix it completely before. I think the recommended solution is to never compare with empty string.

Right now: I'll never have time to fix it completely. Unless Carsten decides to make it a priority.
