    Hello, I've implemented an external widget template for our blog.  This was working great in 4.3.1873, but when we upgraded to 4.3.1885, the control stopped rendering.  It seems that it is still requesting the 4.3.1873 version of the "telerik.Sitefinity.Model" DLL.

    I've tried rebuilding, resetting IIS, clearing ASP.NET Temporary files, changing from CodeBehind to CodeFile and vice-versa, and anything else I could think of, but the error won't go away.  The control partially renders before displaying "Error parsing the template" 

    Here is the actual log:

    Message: HandlingInstanceID: 02e95cbf-c105-4185-a0ae-95565ea44b28

    The code file looks like this:
    protected void rlvBlogPosts_ItemDataBound(object sender, RadListViewItemEventArgs e)
               var dataItem = ((RadListViewDataItem)e.Item).DataItem;
               var post = (BlogPost)dataItem;

               var month = e.Item.FindControl("lblMonth") as Literal;
               //var title = e.Item.FindControl("lblTitle") as Literal;
               var desc = e.Item.FindControl("lblSummary") as Literal;
               var author = e.Item.FindControl("lblAuthor") as Literal;
               //var comments = e.Item.FindControl("lblCommentCount") as Literal;
               var image = e.Item.FindControl("imgPost") as Image;
               var link1 = e.Item.FindControl("lnkTitle") as HyperLink;
               var link2 = e.Item.FindControl("lnkReadMore") as HyperLink;
               var div = e.Item.FindControl("dvPost") as HtmlGenericControl;
               day.Text = post.PublicationDate.Day.ToString();
               month.Text = post.PublicationDate.ToString("MMM");
               //title.Text = post.Title;
               var content = HtmlRemoval.StripTagsCharArray(post.Content);
               desc.Text = content.Length > 400 ? content.Substring(0, 330) + "..." : content;
               author.Text = GlobalMembers.GetUserFullName(post.Owner);
               //var count = post.Comments.Count;
               //comments.Text = count.ToString() + " " + (count == 1 ? "comment" : "comments");
               var imageUrl = GlobalMembers.FetchLinksFromSource(post.Content).FirstOrDefault();
               if (imageUrl != null)
                   image.ImageUrl = imageUrl.ToString();
               var target = GlobalMembers.GetTargetBlogPage();
               if (link1 != null && target != null) link1.NavigateUrl = DataResolver.Resolve(post, "URL", null, target.Id.ToString());
               if (link2 != null && target != null) link2.NavigateUrl = DataResolver.Resolve(post, "URL", null, target.Id.ToString());
               if (e.Item.ItemType == RadListViewItemType.AlternatingItem)
                   div.Attributes.Add("class", "greypost");
                   div.Attributes.Add("class", "whitepost");

    I realize most of that could be done in the markup, but this is more of a concept test for a bigger widget implementation later.  Either way, I need to start working again.  Thanks.

    Well the thing is, if this exists in your web app then it shouldn't be the template having version conflict errors.  I don't see anywhere where there's a version # specified.

    DO you have an external assembly in there or a marketplace component which would be referencing the old assembly versions?

    Steve... Thanks for the reply... I do have additional projects in the solution that use that assembly.  However, the reference is set to the main web application /bin directory, and in the properties window, it shows the correct version number.  However, based on your theory, I went ahead and removed the existing references and pointed them back to the same ones, and voila...all is great again.

    Not sure why the new DLLs didn't update, as this has never been a problem in previous upgrades.

    Anyway, thanks for the suggestion.... It led me to the true problem.  Thanks.

    Hey Amir :)
      Yeah it's a pretty common problem (version conflicts)...99% of the time it's just an old reference, and the last 1% are the problems that make you want to throw your monitor out the window :)

    When I have external components I always turn on Assembly Binding...adds a couple seconds to an upgrade, but saves a TON of headaches :)
