Function addOnError

Register a callback for error handling.

Usage:

const handleError = function handleError(data) {
    // ...
}
faces.ajax.addOnError(handleError);

Implementation Requirements:

This function must accept a reference to an existing JavaScript function. The JavaScript function reference must be added to a list of callbacks, making it possible to register more than one callback by invoking faces.ajax.addOnError more than once. This function must throw an error if the callback argument is not a function.
