My clinics are asking me to provide for a repeating group that could have no items. Trying to do this I have found two issues:
* The CRF is rejected if GROUP_REPEAT_NUMBER is 0.
* If the single item that is displayed is deleted, the validation fails and it tells that required fields are required. That happens even if none of the fields in the repeating group is required.
There is something that I am missing? How could I do this? Seems that it would useful to have this ability.
