Collection(Int 32) missing element

[DDFranky22]

Hi,
I am having an issue with Collections, in detail when SharePoint returns a Collection(Int 32).
I'm trying to take from the website all the supported UI languages, which by documentation is returned as a Collection of Int 32 at the following endpoint: https://<website.link>/_api/Web/SupportedUILanguageIds

I noticed that there wasn't a method in this library to retrieve this kind of information, so I implemented a fairly simple one following the implementation of getRoleDefinitions and other methods available in the Web class.

The collection is declared as a "ClientObjectCollection", even if I'm not sure that is the right kind of object.

Here is the code (note I am passing the Web object to avoid modify the library directly):

public function getSupportedUILanguageIds(Web $web)
    {
        if(!$web->isPropertyAvailable('SupportedUILanguageIds')){
            $collection= new ClientObjectCollection($web->getContext(),new ResourcePathEntity($web->getContext(),$web->getResourcePath(),"SupportedUILanguageIds"));
            $web->setProperty("SupportedUILanguageIds", $collection);
        }
        return $web->getProperty("SupportedUILanguageIds");
    }

So, first question: is that the right object to use? If not, what is the right one?

The call seems to work fine, however due to a validation check in the ODataPayload class, specifically this function:

    /**
     * @param string $key
     * @return bool
     */
    protected function isMetadataProperty($key)
    {
        return $key == "__metadata";
    }

and due to PHP considering 0 equal to every string no matter what, and the return value parsed as an array with key as an integer starting with 0, I am always missing the first value.

Is that intended?
Or should be the function changed with the added condition && is_string($key)?

Thank you.

Indeed, since Web.SupportedUILanguageIds is a primitive property (represented as a collection of signed integer values) it was not properly serialized/deserialized.

In another words, the getSupportedUILanguageIds function represents a valid way for getting so called navigation properties

public function getSupportedUILanguageIds(Web $web)
{
    if(!$web->isPropertyAvailable('SupportedUILanguageIds')){
        $collection= new ClientObjectCollection($web->getContext(),new ResourcePathEntity($web->getContext(),$web->getResourcePath(),"SupportedUILanguageIds"));
        $web->setProperty("SupportedUILanguageIds", $collection);
    }
    return $web->getProperty("SupportedUILanguageIds");
} 

but not for a primitive properties such as Web.SupportedUILanguageIds .
