I remember I did it like this:
public class FilesDataGridColumnEditor extends TextInput {
public function SomeDataGridEditor() {
_validator.source = this;
_validator.triggerEvent = "change";
_validator.required = true;
_validator.property = "text";
}
private var _validator : Validator = new SomeValidator();
}
It's not "the best practices", but as far as I remember it worked. :)
