Validations

Liferay 7.4+

Object validations set rules for determining valid field inputs. You can define validations with Groovy scripts, Liferay expressions, or a specified Composite Key validation. When triggered, the validation checks for valid field inputs according to defined conditions and displays an error message for invalid inputs.

Add field validations to object definitions.

If out-of-the-box validations don’t meet your needs, you can create custom validations using the objectValidationRule client extension. See Microservice Client Extensions for more information.
