I am trying to connect two forms using entities. The first form collects household data then uses a repeat to collect individual information for each household member present. Each household member is assigned a barcode (this occurs inside the repeat). I am trying to use entities here to connect the household form to the test results form. However, when uploading the form to ODK I got the error "The XLSForm could not be converted: [row : 28] Currently, you can't create entities from repeats. You may only specify save_to values for form fields outside of repeats."
Is there a work around here? I am trying to avoid creating an additional form.
We are currently planning out how to add entities from repeats to support your exact scenario, but it won't be available for several months.
As a temporary workaround, is there a maximum number of household members you usually expect? Could you not use a repeat and basically "unroll" or manually copy what would otherwise be in the repeat by referring to specific numbered members? member_01_barcode ... member_10_barcode? You could use a relevant command to only show the next member if the previous one was filled in and it was less than the number of household members? Sorry, this isn't a very elegant solution! But maybe something like this will work for you until we can build support for entities from repeats.
