Импорт данных через modExtra

Всем привет. Продолжаю разбираться в процессорах и интерфейсе на extjs. Пытаюсь сделать импорт по клику на кнопку через компонент. В /assets/components/paypanel/js/mgr/widgets/domains.grid.js добавил:

Ext.applyIf(config, {
        save_action: 'mgr/domain/importapi',

Дальше делаю всплывающее окно с подтверждением действий:

importApiDomain: function(response) {
        Ext.Msg.confirm(
            _('paypanel_action_download') || _('warning'),
            _('paypanel_confirm_download'),
            function(e) {
                if (e == 'yes') {
                    this.setAction('importapi', 'false', 0);
                } else {
                    this.fireEvent('cancel');
                }
            },this);
    },

при нажатии на Да, должен начаться импорт.

Меню делаю так:

getTopBar: function () {
        return [{
            text: '<i class="icon icon-cogs"></i> ',
            menu: [{
                text: '<i class="icon icon-download"></i> ' + _('paypanel_domain_import'),
                cls: 'paypanel-cogs',
                handler: this.importApiDomain,
                scope: this
            }, {
                text: '<i class="icon icon-upload"></i> ' + _('paypanel_domain_update_prices'),
                cls: 'paypanel-cogs',
                handler: this.updateApiDomain,
                scope: this
            }, '-', {
                text: '<i class="icon icon-download"></i> ' + _('paypanel_domain_import_shop'),
                cls: 'paypanel-cogs',
                handler: this.importShopDomain,
                scope: this
            }, {
                text: '<i class="icon icon-upload"></i> ' + _('paypanel_domain_update_minishop'),
                cls: 'paypanel-cogs',
                handler: this.updateShopDomain,
                scope: this
            }]
        },

Пытался сделать свой процессор /core/components/paypanel/processors/mgr/domain/importapi.class.php, но что-то пошло не так:

<?php

    public function initialize()
    {

        $this->paypanel = $this->modx->getService('paypanel');
        $this->paypanel->initialize($this->getProperty('context', $this->modx->context->key));

        return parent::initialize();
    }

    protected function clearTable()

    }

    /** {@inheritDoc} */
    public function process()
    {
        $content = $this->paypanel->getFileContent($this->classKey);
        if ($content == false) {
            return $this->failure($this->paypanel->lexicon('err_file_ns'));

            $domain = str_replace(array('_', '-', '—', '  ', 'idn.'), '', trim($zone));
            $domain = '.'.$domain;

            $procent = $modx->getOption('paypanel_api_regru_percent');

                $object->set('zone', $zone);

            }

            $object->set('domain', $domain);

return 'PayPanelImportApiProcessor';

Буду признателен за любую помощь. Очень хочется победить эту задачу)
