I trying to make attachMany file relation in theme Settings section of October CMS. In my own plugin i wrote

use Cms\Classes\Theme;
use Cms\Models\ThemeData;
use System\Classes\PluginBase;
use System\Models\File;

class Plugin extends PluginBase
{
    public function boot()
{
    ThemeData::extend(function($model){
        $model->attachMany = [ "images" => File::class ];
    });
}

public function registerComponents()
{
}

public function registerSettings()
{
}
}

And in theme.yaml of my theme

form:
    fields:
        images:
            label: images
            mode: image
            useCaption: true
            imageWidth: '100'
            thumbOptions:
                mode: crop
                extension: auto
            span: auto
            type: fileupload

So in Backend->Settings->CMS->Front-end Theme appeared new button "Customize" and my field images inside. But when i choose Upload I can select only one file!

So it works like attachOne instead of attachMany. Seems like the boot() method of Plugin doesn't work at all.

What am I doing wrong?

The theme model is special and automatically assign fields of type "fileupload" to its $attachOne relation.
