SpriteCssClasses not being rendered on child nodes loaded via Ajax

[Emily Hatch]

I have a conditional statement that changes the CSS class to render a specific icon when the condition is met.  This works flawlessly on the root parents nodes.  When the Ajax call is made to load the child elements, the SpriteCssClasses attribute it set correctly however it does not render the icon in the tree.  Note:  Even when I remove the conditional and always set the child nodes to render the icon, the icon does not appear.

 

 

IEnumerable nodes = from item in treeItems
                    select new TreeViewItem
                    {
                       Text = item.Name,
                       Value = item.RelativePath,
                       LoadOnDemand = item.HasChildren,
                       Enabled = true,
                       ImageUrl = (item.ItemType == TreeItem.Type.Folder)
                                  ? Url.Content("~/Content/Images/folder.png")
                                  : Url.Content("~/Content/Images/file.png"),
                        SpriteCssClasses = (item.HasBeenMigrated)
                                            ? "migratedFile" : null,
                        Checkable = IsCheckable(item),
                        Checked = (ps2CheckedNodes != null)
                                   ? (ps2CheckedNodes.Where(e =>
                                   e.Value.Equals(treeItem.RelativePath))
                                    .FirstOrDefault() != null) : false
                     };

I'm getting this issue with version  2011.2.629.235.  The span tag for the sprite is not rendered when the child nodes are loaded via ajax.
