Table view shows multiple columns for grouped questions #2249
Description
Given a simple form with a grouped question:
| type | name | label |
|---|---|---|
| start | start | |
| end | end | |
| text | not_in_a_group | not in a group |
| begin_group | the_group | the group |
| text | in_a_group | in a group |
| end_group |
And, given an unremarkable submission:
{
"_notes": [],
"__version__": "vdKnsdwokQcYE7zQQ8bMAe",
"meta/instanceID": "uuid:ee19bcd5-7dcd-4b93-8437-bd049ffb6789",
"end": "2019-04-15T16:14:01.870-04:00",
"_submission_time": "2019-04-15T20:14:07",
"_validation_status": {},
"_uuid": "ee19bcd5-7dcd-4b93-8437-bd049ffb6789",
"_bamboo_dataset_id": "",
"_tags": [],
"_attachments": [],
"start": "2019-04-15T16:13:54.503-04:00",
"_submitted_by": null,
"_geolocation": [
null,
null
],
"_xform_id_string": "ahrzuYwQpBZqnu2LWm7dtV",
"the_group/in_a_group": "yep!",
"_status": "submitted_via_web",
"_id": 25966712,
"not_in_a_group": "nope!",
"formhub/uuid": "0ea52d3d7e4d4bd88fc8619b0c91a277"
}The table view columns (set to XML Values for clarity) include the_group, the_group / in_a_group, and in_a_group. I would expect only the_group / in_a_group to appear, unless Show group names in table headers were unchecked; in that case, I would expect only in_a_group to appear.
The same behavior occurs in the "Restrict the visible columns in the table display" list inside the "Table display options" modal.
