Problem with BaseControlTrait in my class extending Nette\Forms\Controls\TextInput

[mprof]

When using Nextras\FormComponents\Fragments\Traits\BaseControlTrait in my class representing live form server validation, then occours error with method getControl() (origin in BaseControlTrait):

TypeError: Nette\Forms\Helpers::exportRules(): Argument #1 ($rules) must be of type Nette\Forms\Rules, null given

Seems like $this->rules variable is empty, when using this trait.

What is the namespace of the TextInput you inherit from? Since if you are using https://github.com/nextras/form-components/blob/master/src/Fragments/UIControl/TextInput.php you shouldn't use traits.

Namespace of inherited TextInput is: Nette\Forms\Controls (like in your solution)

I am trying to reproduce your solution posobota-2014-server-validation in actual version of Nette, so everything is almost same, but when use BaseControlTrait, described error occurs.

https://github.com/nextras/form-components/blob/master/src/Controls/AutocompleteControl.php
