When i installed that module and after enabled i go to the product page at backend, then click on any product ad go to details page, There i find that A new tab "Preorder" is available. When i click on that tab then it's page are working but i have a problem that when i Click on "Product variant" Tab the it throw an error as below :

ERROR: "Includes\ErrorHandler::FATAL_ERROR" (code 2)
Call to a member function toArray() on null

and when i uninstalled preorder module that that "Product Variant" tab is working fine.


The code for the "Pre-order" module at path to call the preorder page is as below

classes/XLite/Module/Wevbkulsoftware/PreorderSales/Controller/Admin/Product.php

PHP Code:

/**
     * Page key
     */
    const PAGE_VARI = 'preorders';


public function getPages()
    {
        $list = parent::getPages();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0, 5),
                array(static::PAGE_VARI => static::t('PreorderSales')),
                array_slice($list, 5)
            );
        }

        return $list;
    }



protected function getPageTemplates()
    {
        $list = parent::getPageTemplates();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0,5),
                array(static::PAGE_VARI => 'modules/Webkulsoftware/PreorderSales/preorders/body.twig'),
                array_slice($list, 5)
            );
        }

        return $list;
    } 


And code for the module "Product variant" at path below
classes/XLite/Module/XC/ProductVariants/Controller/Admin/Product.php

is

PHP Code:

/**
     * Page key
     */
    const PAGE_VARIANTS = 'variants';
/**
     * Get pages
     *
     * @return array
     */
    public function getPages()
    {
        $list = parent::getPages();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0, 2),
                array(static::PAGE_VARIANTS => static::t('Variants')),
                array_slice($list, 2)
            );
        }

        return $list;
    }

    /**
     * Get pages templates
     *
     * @return array
     */
    protected function getPageTemplates()
    {
        $list = parent::getPageTemplates();

        if (!$this->isNew()) {
            $list = array_merge(
                array_slice($list, 0, 2),
                array(static::PAGE_VARIANTS => 'modules/XC/ProductVariants/variants/body.twig'),
                array_slice($list, 2)
            );
        }

        return $list;
    }
