Mutli-file snippets - Improve file validation messages
Everyone can contribute. Help move this issue forward while earning points, leveling up and collecting rewards.
Description
Currently in multi-file snippets we do not have any helpful live-feedback for validation issues on the files:
- Content is required.
- Two files can't have the same name.
Even when the for is submitted there is not very helpful information in the error message (i.e. which file is causing validation issue).
Proposal
Per our design guide it would be nice to show some nice client-side inline validation while editing snippets so that we can help guide the user to creating successful submissions.
Design Proposal
If a user enters a name that has already been used by another file, display an inline error message There is another file with this name. File names must be unique.
Availability and Testing
Please run a regression job package-and-qa to ensure happy path scenarios still pass. We might need to introduce low level test verification for the error logic.
