20.1.2 Using Validations for Multiple Errors

All validation errors show at once so users can review and fix them in one step.

All failed validations automatically display as shown below. You can associate field-specific validations with the relevant page item, and configure them to show inline with the field. Validation error messages with no specific field show in the notification area. The figure shows a page with two number input fields Multiple of Ten and Odd Multiple of Five. The user has entered 44 in the Multiple of Ten field, and 40 in the Odd Multiple of Five one and clicked (Submit). A field-specific validation error message shows just below each field. Four error messages display in the error notification area as a bulleted list:

• Must be a multiple of ten
• Must be an odd number
• Cannot both start with a 4
• At least 1 must be greater than 100
