Yes/No attribute value is not shown on a product details page

[alexkuk]

Preconditions

• Magento CE 2.1.1 with sample data (Luma theme).

Steps to reproduce

1. Navigate to the backend.
2. Go to Stores -> Attributes -> Product
3. Click on the Add New Attribute button
4. Set "Catalog Input Type for Store Owner" = Yes/No, set "Visible on Catalog Pages on Storefront" = Yes, and fill other required fields.
5. Click Save Attribute button
6. Go to Products -> Catalog. Click on some product that is visible on storefront.
7. Find the newly created attribute field and fill it with Yes or No value. Save product.
8. Clean cache and reindex:

$ bin/magento cache:clean
$ bin/magento indexer:reindex

1. Open a storefront product page.

Actual result

The More Information tab doesn't contain our newly created attribute.

Expected result

The More Information tab contains our newly created attribute.

Additional information

If I make some yes/no attribute visible on frontend, it doesn't appear in the More Information tab on a product details page. I debugged it and found that this relates to the fact that translated string are wrapped into the Phrase object: https://community.magento.com/t5/Magento-2-Feature-Requests-and/function-returns-Phrase-object-Could-this-return-string/idi-p/45075

Particularly, it's \Magento\Catalog\Block\Product\View\Attributes::getAdditionalData() - it requires $value to be string to be added to the $data array. In case of Yes/No attributes $value is an object of \Magento\Framework\Phrase.

Yes/No Attributes are not visible on frontend due to error in the file

-/Magento/Catalog/Block/Product/View/Attributes.php

function getAdditionalData(array $excludeAttr = []) check if the attributes value is string but in case of Yes/No Attributes the value is something like this -

object(Magento\Framework\Phrase)#2322 (2) { ["text":"Magento\Framework\Phrase":private]=> string(3) "Yes" ["arguments":"Magento\Framework\Phrase":private]=> array(0) { } }

here is the check for string -

if (is_string($value) && strlen($value)) {
$data[$attribute->getAttributeCode()] = [
'label' => __($attribute->getStoreLabel()),
'value' => $value,
'code' => $attribute->getAttributeCode(),
];
}

other attribute types are working fine for me.

When will this be fixed?

When will this be fixed. Has been open for a long time.

This is our solution:

Extend the condition for attributes that are instances of \Magento\Framework\Phrase.

use Magento\Framework\Phrase;
...
if ($value instanceof Phrase || (is_string($value) && strlen($value))) {
    $data[$attribute->getAttributeCode()] = [
        'label' => __($attribute->getStoreLabel()),
        'value' => $value,
        'code' => $attribute->getAttributeCode(),
    ];
}
