Umbraco.CheckBoxList data type not syncing

[saadan]

When Im trying to add new prevalues to a checkBoxList property an sync with live the selected values on live get deselected.

Reproduction

• Add a Umbraco.CheckBoxList property to a document type and add some pre-values
• Sync the new pre-values to cloud (e.g. Local to Live)
• Create a node on live with the property and select a value from the checkBoxList
• Go back to the local environment and add a new pre-value to the Umbraco.CheckBoxList property
• Sync the new pre-values to cloud again
• Now if you look at the live environment and find the node where the checkBoxList property should have a selected value it has been deselect visually.

Expected result

The property on the destination environment should have the same selected value as before the second sync.

Actual result

The property on the destination environment doesn't have a selected value after second sync.

the issue looks alot like this umbraco/Umbraco.Cloud.Issues#20

Hiya @saadan,

Just wanted to let you know that we noticed that this issue got a bit stale and might not be relevant any more.

We will close this issue for now but we're happy to open it up again if you think it's still relevant (for example: it's a feature request that's not yet implemented, or it's a bug that's not yet been fixed).

To open it this issue up again, you can write @umbrabot still relevant in a new comment as the first line. It would be super helpful for us if on the next line you could let us know why you think it's still relevant.

For example:

@umbrabot still relevant
This bug can still be reproduced in version x.y.z

This will reopen the issue in the next few hours.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Thanks for the bug report with exact steps! And apologies for taking so long to have a look at this one 😬

I have been able to reproduce this now, even in the latest version. Here's what I can see happening:

My checkbox list, before deploy from local to live looks like this (when loading the content page in the backoffice, so this data is coming back from /umbraco/backoffice/UmbracoApi/Content/GetById?id=1053):

		"label": "Check list",
		"description": null,
		"view": "checkboxlist",
		"config": {
			"items": {
				"22": {
					"value": "test1",
					"sortOrder": 1
				},
				"23": {
					"value": "test4",
					"sortOrder": 2
				},
				"24": {
					"value": "test2",
					"sortOrder": 3
				},
				"25": {
					"value": "test6",
					"sortOrder": 4
				},
				"26": {
					"value": "test3",
					"sortOrder": 5
				},
				"27": {
					"value": "test5",
					"sortOrder": 6
				},
				"28": {
					"value": "test7",
					"sortOrder": 7
				}
			}
		},
		"hideLabel": false,
		"validation": {
			"mandatory": false,
			"pattern": null
		},
		"readonly": false,
		"id": 7,
		"dataTypeId": "fbaf13a8-4036-41f2-93a3-974f678c312a",
		"value": ["22", "23", "24", "25"],
		"alias": "checkList",
		"editor": "Umbraco.CheckBoxList",
		"isSensitive": false
	}],

After adding another prevalue (test8) and deploying that to Live, surprisingly, I see the exact same coming back from /umbraco/backoffice/UmbracoApi/Content/GetById?id=1053. However, none of the checkboxes are checked, as reported.. 😞

But I also don't see test8, so something else is wrong. I figure it's some kind of caching issue, so after restarting the site I checked again: test8 has appeared, but nothing is checked.

So then having another look at the response from /umbraco/backoffice/UmbracoApi/Content/GetById?id=1053 I now see the following:

		"label": "Check list",
		"description": null,
		"view": "checkboxlist",
		"config": {
			"items": {
				"29": {
					"value": "test1",
					"sortOrder": 1
				},
				"30": {
					"value": "test4",
					"sortOrder": 2
				},
				"31": {
					"value": "test2",
					"sortOrder": 3
				},
				"32": {
					"value": "test6",
					"sortOrder": 4
				},
				"33": {
					"value": "test3",
					"sortOrder": 5
				},
				"34": {
					"value": "test5",
					"sortOrder": 6
				},
				"35": {
					"value": "test7",
					"sortOrder": 7
				},
				"36": {
					"value": "test8",
					"sortOrder": 8
				}
			}
		},
		"hideLabel": false,
		"validation": {
			"mandatory": false,
			"pattern": null
		},
		"readonly": false,
		"id": 7,
		"dataTypeId": "fbaf13a8-4036-41f2-93a3-974f678c312a",
		"value": ["22", "23", "24", "25"],
		"alias": "checkList",
		"editor": "Umbraco.CheckBoxList",
		"isSensitive": false
	}],

The problem, as we can see now, is that the identifier for each prevalue item has change, test1 changed from 22 to 29, test2 from 23 to 30. This doesn't match up with the array of selected values any more ["22", "23", "24", "25"].

Not sure why the identifiers have been updated but that's probably a mistake, no need to change them.
