        This call needs careful usage as data loss can occur. If the

        created and initialize by the document model or the module user
        interface configuration supplier. Normally there is no need to
        set a storage for a user interface configuration manager. If a
        copy of the configuration data to another storage should be made,
        use <member>storeToStorage</member>.
