Im new in magento 2. using DI.xml I'm creating a price adjustment. Weird to find that argument -> inside arguments is displayed in red with error cannot resolve 'array' to a type definition for element 'argument'.
any idea if it changed in the last release?.
UPDATE-------------------------------------------------------------- I realized in C:\Zend\Apache2\htdocs\magento2\lib\internal\Magento\Framework\ObjectManager\etc\config.xsd is not defined. error says 'URI is not registered'
