Validation Error That Wipes Out Other Already-Valid Fields
3.3.7 — Redundant Entry
Scenario
Setting
A calendar app's event-creation form
What’s wrong
Error recovery wiping unrelated valid fields, forcing redundant re-entry.
Example
Here's what happens on a calendar app's event-creation form: error recovery wiping unrelated valid fields, forcing redundant re-entry.
Why it matters
People with cognitive or motor disabilities who are harmed by retyping the same data. On a calendar app's event-creation form, this barrier means they can't complete the form at all.
How to test
Trigger a validation error on one field: if it wipes other, unrelated valid fields and forces their re-entry too, it fails.
How to fix
Previously entered information must be auto-populated or selectable — never demanded again in the same process.
Outcome
Corrected, a calendar app's event-creation form now lets a visitor finish the task in one attempt.
Who is affected
People with cognitive or motor disabilities who are harmed by retyping the same data.
