Once() not working in new body::esri:visible column

ByronTsang — Thu, 19 May 2022 19:46:01 GMT

In an older (pre- body::esri:visible functionality) survey, I used the once() function in my Relevant expressions to turn fields on as needed, but to retain them if the upstream relevance trigger was changed. That function seems to no longer work in both the Relevant and body::esri:visible columns.

In both, I'm finding that changing the field that triggers relevance/visibility continually re-evaluates, seeming to ignore the once() function entirely. Did something change? am I missing something obvious?

Hello @ByronTsang,

One alternative workflow you can use is use a calculate question to store the once calculation, then set the relevancy based on the calculate question.

For example:

type	name	label	calculation	relevant
select_one yes_no	example2	Example select_one question
note	example4	Example 4	once(${example2})
text	example3	Example 3		${example4}='yes'

Thanks, Zach - I'll give this a try.
