When set to true, setting an invalid value for an Enum attribute and/or setting a value for a Calculated attribute will result in an InvalidEnumerationValueException and/or ReadOnlyAttributeException respectively.
When set to false, changes to the values of Enums and/or Calculated attributes will be allowed.
We plan to remove this setting in Mendix 11, after which, an exception will always be raised when setting an invalid value. | true |

When this happens, a database update query has to be sent, which can have performance consequences on heavy load systems. When this setting is set to `false`, no database interaction is necessary. Ths setting is not available in Studio Pro 10, because this behavior is included in the [TrackWebServiceUserLastLogin](#TrackUserLastLoginForODataAndREST) setting.
