  * NOTE1: lodash.merge & lodash.mergeWith prefers to ignore undefined values
  * NOTE2: special handling of `domNode` option is now required as `deep-extend` will corrupt it (lodash.merge handles it correctly)
  * NOTE3: oauth2RedirectUrl and withCredentials options can be set to undefined. By expecting null instead of undefined, we can't use lodash.merge.
+ * NOTE4: urls.primaryName needs to handled in special way, because it's an arbitrary property on Array instance
