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.
