O parâmetro de configuração "componentType" é necessário para o componente "advanced_pricing_button". | Atualizar Magento 2.0.7 => 2.1.0

Depois de muitos problemas, consegui atualizar o Magento 2.0.7 => Magento 2.1.0

Após verificar a atualização, vejo 2 problemas: 1. O front-end não está exibindo nenhum produto. 2. Quando desejo editar os produtos no administrador, recebo o seguinte erro:

1 exception(s):
Exception #0 (Magento\Framework\Exception\LocalizedException): The configuration parameter "componentType" is a required for "advanced_pricing_button" component.

Exception #0 (Magento\Framework\Exception\LocalizedException): The configuration parameter "componentType" is a required for "advanced_pricing_button" component.

Alguém corrigiu esse problema?

Teve o mesmo problema ao migrar do Magento 2.0.7 para o 2.1.0, o seguinte WAR descrito em https://github.com/magento/magento2/issues/5236 corrigiu o problema para mim:

Em vendor/magento/module-configurable-product/Ui/DataProvider/Product/Form/Modifier/ConfigurablePrice.phpolhar para o seguinte código:

$meta[$groupCode]['children'][self::CODE_GROUP_PRICE] = array_replace_recursive(
    $meta[$groupCode]['children'][self::CODE_GROUP_PRICE],
    [
        'children' => [
            self::$advancedPricingButton => [
                'arguments' => [
                    'data' => [
                        'config' => $visibilityConfig,
                    ],
                ],
            ],
        ],
    ]
);

E substitua a seguinte linha:

'config' => $visibilityConfig,

Com:

'config' => ['componentType'=>'container',$visibilityConfig],

Se você não encontrar nenhum campo preenchido no seu catálogo de produtos Magento BE, verifique outros produtos. No meu caso, alguns produtos mostrariam o seguinte erro:

Aviso: deslocamento indefinido: 118 em /......./vendor/magento/module-eav/Model/ResourceModel/ReadHandler.php na linha 166

Isso acontece porque a tabela catalog_product_entity_varcharcontém um atributo que não existe em outras tabelas. No meu caso, o problema foi resolvido ao remover as entradas attribute_idlistadas no erro acima:

mysql> delete from catalog_product_entity_varchar where attribute_id=XXXXXXX;
Query OK, 7890 rows affected (0.11 sec)
