once(join()) work differently on the first repeat

dougbrowning

When I use once(join)) inside of a repeat the first records works differently. It adds it right away where all other repeats adds it after the move to the next repeat. I am trying to get around this using position but I use pages which means it is in a group which means it always returns 0.

First repeat

Second repeat is the same

3rd repeat see how the last value is not on the list.

I maybe got around it by counting a field in another field after the list and then checking that field to adjust my check. May not make sense but it seems that the order matters. So if I count a field before that field I do not get the count you are on but if I count it after I do get it.

Thanks

Hi @DougBrowning,

Does this appear to be new or different behavior with the recent 3.14 release, or did you see the same thing before with 3.13?

Are you able to send us this form (updated copy) so we can take a closer look?

Thanks,

Phil.

I think new to 3.14 but not sure. I had to change the code since 3.14 broke my dups check trick. I ended up having to code around it by checking if it was the first repeat. This was actually hard since I had to count a field that was after the constraint field - which took a few hours to track down.

if(${TempCount}=0, 1,${Species}='' or contains(${Species}, "xyz") or not(contains(${AllPlantsCheck}+",",${Species}+",")))

I will email you the form. Thanks

Hi @DougBrowning and Phil. Was this ever resolved? I am having the same issue. Thank you!

Update to myself. 2 years later and it is still doing it. I finally found a fix. If you set your count field that has a calc of 1 to also have a default value of 1 then the repeats calc properly.

@DougBrowning Im trying to create a very similar survey and struggling to understand using Once() in repeats. Would you be happy to share XLS form to help me understand how it works properly?

Just have a field with 1 in it then a second field is once(count())

Thanks, I figured out I wasn't actually needing to use the once() function. I wanted to have a select multiple that populated into repeats but also updated itself when the select multiple list was changed, but regardless of the order they were selected.

Instead I used this: selected-at(${species_choice},position(..)-1)
