So I knew the uQuery/uComponents got rolled into Umbraco around Umbraco 4.7. But we have some old uQuery calls that we are using that needs updated or changed, because our we have had a broken Macro for a while that we need to fix now.  

Below is our code, can anyone help us figure out what the issue is?  I took out the using uComponents reference a while back to try to see if that fixed it, but of course I did not see that as working.   Any help is greatly appreciated.

@using umbraco;
@using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNode
@inherits umbraco.MacroEngines.DynamicNodeContext
@using DWTBlog;


@{

  var baseNode = @Model.AncestorOrSelf("DWTBlogLanding");

  var newNode = uQuery.GetRootNode().GetDescendantNodes().Where(x => x.HasProperty("alternateAuthor") && x.NodeTypeAlias == "ScienceResearchUpdatesPost").OrderBy(x => umbraco.BusinessLogic.User.GetUser(x.GetProperty<int>("alternateAuthor")).Name);

    @*
    var newNode = @n.Children.Where("\"alternateAuthor\" != null && NodeTypeAlias == \"ScienceResearchUpdatesPost\"").OrderBy(x => umbraco.BusinessLogic.User.GetUser(x.GetProperty<int>("alternateAuthor")).Name);
    *@

  string altAuthorList = "";

  <h3>Authors</h3>
    <ul>
      @foreach(var node in newNode)
      {
        var user = umbraco.BusinessLogic.User.GetUser(node.GetProperty<int>("alternateAuthor"));

        if (altAuthorList != user.Name)
        {
          var numOfPosts = NumberOfBlogsByAlternateAuthor(newNode, node.GetProperty<int>("alternateAuthor"));
          if (numOfPosts > 0)
          {
           if(user.Name == "Administrator" || @node.CreatorName == "Administrator"){

            }
           else{
            <li><a href="@[email protected]&page=1">@user.Name (@numOfPosts)</a></li>
             }
          }
          else
          {
            @*<li>@node.CreatorName (@numOfPosts)</li>*@
          }
        }

        altAuthorList = user.Name;
      }
