| - When an item [template](/api-reference/10%20UI%20Components/dxForm/5%20Item%20Types/SimpleItem/template.md '/Documentation/ApiReference/UI_Components/dxForm/Item_Types/SimpleItem/#template') is configured, do not specify this property. Configure a [Validator](/Documentation/ApiReference/UI_Components/dxValidator/) within the template and specify **Validator**.[validationRules](/Documentation/ApiReference/UI_Components/dxValidator/Configuration/#validationRules) instead. | ||
| - The Form is repainted when you update **validationRules** as follows: | ||
| - When you add or remove [RequiredRule](/Documentation/ApiReference/UI_Components/dxValidator/Validation_Rules/RequiredRule/). | ||
| - When you set **validationRules** to empty or add a rule to an empty **validationRules**. |

There was a problem hiding this comment.
For my understanding, when you say "empty", are you actually setting validationRules to an option called empty?
Or are you setting validationRules to an empty array like []?
If it's the latter, could we say something like:
- When you set **validationRules** to an empty array or add a rule to an empty **validationRules** array.
