Repeat_count not working

Dear friends,

I'm working on a form which has two repeat groups. The first one records
the information about all household members and another one recording the
education of the household member. Problem is that I want to limit the
occurrence of the second group based on the number of household members
recorded in the first group. It seems that repeat_count should be used for
the job but it makes ODK collect crash. If I remove the corresponding
syntax, it works fine.

Here is more detailed structure of my form (I've omitted unnecessary
fields):

     repeat_count  begin repeat roster Household members    calculate 

mid text name Name select_one gender_list gender Gender integer
age Age calculate age6 calculate agem select_one yesno empl Are
you employed end repeat begin repeat education Education
count(${roster}) calculate rname calculate rpos calculate age6_c
calculate age6_d Was this question asked? Y/N select_one edu_list
edu6 What's the highest level of education ${rname} has achieved? end
repeat

Thanks in advance,

David

David,

What happens if you use an output to see what you get when call
count($roster). Do you get the number you expect?

What happens if you put a number in repeat_count. Does it work then?

Yaw,

When I load blank form, it yields following error message: XPath
evaluation: type mismatch expected xpath path, got xpath expression:
"[count(/oecd[It's my form name]/responde[it's group name]/roster[it's
repeat name]), null]".

I've added calculate field and note which would compute and display the
count number of repeats, but I'm getting similar error with the following
tip: "you may need to use the indexed-repeat() function".

Thanks,

David

Hi David,

This might be one of those issues where referencing repeats in XLSForm
causes problems. Or it just might be that count cannot be updated
inside a loop.

Either way, I don't have a ton of cycles to figure it out, so I've
filed it at https://code.google.com/p/opendatakit/issues/detail?id=1020.

If you can provide a small test form you can attach to that issue,
it'll keep the core team track down the problem.

Hi Yaw,

Sorry for the delayed response.

Actually, it appears that there's a workaround - I put a calculate field
OUTSIDE of the first repeat group and then referred to this variable in the
second group's repeat-count property. Something like:

end repeat / household roster/

cntRoster / count(${roster})

begin repeat / repeat_count / ${cntRoster}

Hope it helps other people as well,

D.
