Is there way to prevent data loss while working in a form with a relevant group or repeat. It seems that when a repeat or group is hidden, the data is lost. I have tried to hide individual fields and not the whole repeat or group.
The nature of relevancy is to determine whether or not a question should submit data; when non-relevant, a question will be set to null. If you want to visually hide/show a question, place it in a group that can be expanded/collapsed.
