Retain form input on error.
Benefits of conformance
- Increased error recovery rate.
- Increased trust (by respecting the customer).
Risks of non-conformance
- Increased customer frustration.
Fields that were populated before the error occurred must remain populated with the same data after the error. Form data must not be cleared – or otherwise altered – on detecting an error.
Correct implementation: Where user data was entered it has been retained on error.
