Working example of linked_table functionality in rev210

Support
1

Hi ODK Community,

I was not sure if I should post my ODK2.0 question here or in support. Since I’ve seen other support-like ODK2.0 questions posted here instead of support. Anyways, I’ve been able to successfully setup the rev210 app-designer based on the rev208 “getting started” documentation.

I was able to add my forms to the framework.xlsx file and test them out. However, I noticed that whenever I had a properly configured linked_table entry in my form, the app-designer would not be able to load up the new form and instead display “please wait…” in the app “preview” view.

At first I thought that I mis-configured the linked_table entry, but when I ran the household (and related household_member) forms (the bundled examples with ODK2.0 app designer), they also exhibited the same problem.
Using Shift-Ctrl-J to display the problem, mentions some type error for undefined, if I recall correctly; this same error is displayed for both my form and the household/household_member forms.

Ultimately, I just need to see a working XLSX example with linked_table, and I should be able to ‘reverse-engineer’ what I need to do.

Regards,
Dave

I just tried to preview the household form in App Designer 210 RC1 and it works fine. I also tried the form in Survey 210 RC1 and it also works fine. I’m using Chrome 62 and Android 7.1.1 emulator.

Could you share the error you got, steps you took to get the error (grunt command, buttons clicked in App Designer, etc.) and the browser you are using (name and version)? So that we can better understand what is the issue you have.

Hi Lin,

Have you been able to make sense of this error? Thanks!

Hi,

We are working on fixing the issue in App Designer. You will have to use Survey to use the linked_table function for now.
