dependency-injectionmagento2xml
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'
You can't instantiate an object of form without passing argument. Please refer file Magento\Framework\Data\Form.php wherein construct function there are four arguments (one is an array) so you must pass three arguments during initiate object of Form:
class Form extends \Magento\Framework\Data\Form\AbstractForm
{
public function __construct(
Factory $factoryElement,
ElementCollectionFactory $factoryCollection,
FormKey $formKey,
$data = []
) {
parent::__construct($factoryElement, $factoryCollection, $data);
$this->_allElements = $this->_factoryCollection-create(['container' => $this]);
$this->formKey = $formKey;
}
}
Your argument is not matching with construct function.
The exception thrown tells you that you're using an element <item /> where your not allowed to use one. So yeah, your problem is probably XML-related.
The first thing I do to make sure I write valid XML is setup my IDE so it can properly map the XSD-schemes. In PhpStorm you can do this by using the helper-thingy left to the xsi-namespace:
When all is set properly, your IDE will setup code completion for you and warn you if you're doing something that is not allowed:
I hope this helps you some.
