    umbraco.library.GetMedia only finding node on first try after Republish Entire Site

    Hi,

    Strange problem with a 4.5.2 site.

    I'm using umbraco.library.GetMedia in some backend code. Here's the code:

    public string GetMediaFile(string nodeId)
    {
          string url = String.Empty;
          int mediaId = 0;
          if (Int32.TryParse(nodeId, out mediaId))
          {
              XPathNodeIterator xn = umbraco.library.GetMedia(mediaId, false);
              //This movenext fails on the second request
              if (xn.MoveNext())
              {
                  XPathNodeIterator xn2 = xn.Current.Select("data[@alias='umbracoFile']");
                  if (xn2.MoveNext())
                  {
                        url = xn2.Current.Value;
                  }
              }
           }
           return url;
    }

    The thing is it only returns the media item on the first request after a republish.

    Very strange. Would anyone have any idea why this might be happening?

    Just discovers that setting the umbraco library cache duration to 0 fixes the problem - so something is wrong with the cache? Or should I be using another method to get media url in codebehind?

    <UmbracoLibraryCacheDuration>0</UmbracoLibraryCacheDuration>

    I was looking at the source, and it seems that there might be a bug.

    What does it return if you do this:

    public string GetMediaFile(string nodeId)
{
    string url = String.Empty;
    int mediaId = 0;
    if (Int32.TryParse(nodeId, out mediaId))
    {
        XPathNodeIterator xn = umbraco.library.GetMedia(mediaId, false);
        //This movenext fails on the second request
        if (xn.MoveNext())
        {
            return xn.Current.OuterXml;
        }
    }
    return url;
}

    I'm guessing you might get something like "<error>No media is maching '{0}'</error>"

    We have had the same issue happen to use for about 6-7 months now and could not figure out the issue, but it was happening with our XSLT files.  Thanks for the find, but that is kind of a horky fix.  Caching would be nice.  Is there a fix? We are using Umbraco 4.7.1
