I am running a pilot using ODK Central and the App Users function where I am regularly updating form definitions and pushing updates to App Users. After my last update, I have had a problem with lost data in fields/columns that were maintained across definitions.
More specifically, the values for a series of columns that exist in both definitions were deleted.
I'm attaching screen shots of a data pull made on 12/03, showing the columns with only one submission row where previously there were about 17. Will attach the screen shot of a previous pull I made on 11/23 showing the same columns with correct submissions in the first comment
I had been regularly updating form definitions before and after the 11/23 pull with no problem until the latest definition. I was pulling data with ruODK and OData, but I don't think this is the problem. The data for those fields truly gone - I can't access it even in the "edit submission" Enketo viewer.
The only thing I can think that might have caused this problem is that I added a few questions at the beginning of my form, so that subsequent questions are shifted down a few positions. It seems that the data for the 3 questions before the additions has been preserved.
Could this addition of questions have caused the data erasure? If not, what else might have? I'm a little worried about rolling out the finalized survey (planned for the next few days) without understanding what caused this loss!
