On a product node there is form with a button “add to cart” that is implemented with form API (ajax):
$ form['add_to_cart'] = array( '#type' => 'button', '#value' => $ this->t('Add to cart'), '#ajax' => array( 'callback' => 'Drupal\custom_cart\Form\AddToCartForm::addProductToCart', 'event' => 'click', 'effect' => 'fade', 'wrapper' => '#custom-cart', 'progress' => array( 'type' => 'throbber', ), ) );
This works as expected.
For a product overview page we render out product nodes with a view (node teasers) and the view includes some exposed filters. If the view is ajax enabled the ajax callback from the “add to cart” button (breaks) and returns a 404 error:
Request URL:http://foobar.lo/views/ajax?_wrapper_format=drupal_ajax Request Method:POST Status Code:404 Not Found
Does somebody know how to fix this (core patches anywhere?) or a workaround you know?
Thanks for any advice
