# Additional Validations

## Using Helper Class Validations Only

If only validations from the helper class are required, use the Change Handlers `getValidationRules()` method to return the `helper.getValidationRules()`. This will enforce all the validations in the Helper class on the Change Handler.

Sample code:

    public ValidationRule[] getValidationRules() {
    	return helper.getValidationRules();
    }

## Using Helper and Change Handler Validations

Create an Array of `ValidationRules` in the `getValidationRules()` method of the Change Handler and pass this array to the `helper.getValidationRules()` method. The Helper class adds the rules passed to it to the standard set to provided validations.

Sample code:

    public ValidationRule[] getValidationRules() {
    	return helper.getValidationRules(<Array of Validation Rules>);
    }
