(updater) => {
updater.form.addValidation(
'AssetAdmin.*',
(values, errors) => ({
...errors,
PostalCode: values.PostalCode.length !== 5 ? 'Invalid postal code' : null,

(values, validator) => {

```
The `addValidation()` function takes a callback, with an instance of `FormValidationManager` (`validator` in the above example) as a parameter. `FormValidationMangaer` allows you to manage the validation result using several helper methods, including:
* `addError(fieldName:string, message:string)`
* `addErrors(fieldName:string, messages:Array)`
* `hasError(fieldName:string)`
* `clearErrors(fieldName:string)`
* `getErrors(fieldName:string)`
* `reset(void)`
