    running a template on a data object of pictures returned from facebook

    Object {data: Array[8]}
    data: Array[8]
    __proto__: Object

    sometimes the object returns an additional array of 'paging', sometimes it doesn't

    How can I get something like this?

    <script id="albums-photos-template" type="text/x-kendo-template">
    # if (paging) { #
    # if (paging.previous) { #
    <a href='#= paging.previous #' class='albums-prev'>prev</a>
    # } #
    # } #

    I'm getting something like this

    Uncaught ReferenceError: paging is not defined

    Hi Phil,

    You may use the typeof operator - if paging is not present, it will return undefined.
