• Added confirmation when delete labels via Raw editor (it was implicitly before)
• A bit adjusted behaviour of labels editor in general

How has this been tested?

@klakhov Could you please review the patch? Try to value the solution and find cases when it does not work

[bsekachev]

@nmanovic

Maybe additionally to delete on the server label/attribute IDs when create a new task/project?
And when updating a task/project, to delete any unknown IDs?

[klakhov]

@bsekachev I've tried patch and it works as expected. No errors occur after labels copying.

Also I think its better to hide deleted labels/attributes paragraph if list is empty:

Btw why do we need to remove carriages if textarea does not contain them?

// remove all carriage characters (textarea value does not contain them)
replaced = replaced.replace(/\r/g, '');

I did the proposed changes above

Sure, I did.

Btw why do we need to remove carriages if textarea does not contain them?

It is related with textarea properties selectionStart, selectionEnd. They don't consider \r characters (maybe it is a bug, I don't know). Also when we enter something manually it does not add \r characters to the field (and does not add it when we fill out the field from a labels specification). So, I've decided just to ignore all such characters from clipboardData because they can appear only from this place.

@bsekachev , I'm find with the PR. The only concern I have for now is about update operation and removing id. Could you please share your ideas why you think the implemented solution is right?

@dvkruchinin

Could you please prepare a test with the following scenario:

1. From an existing task copy all labels and attributes (from the Row tab of the labels editor) (It must have at least one task and one attribute)
2. Go to the project create page, in the labels editor paste the copied text (ctrl + v)
3. Inserted JSON copy must not contain any "id": fields
4. A project can be created with no errors
