Implementing dynamic content plugin - RSS feed

Vote:
 

Hi,

I'm currently trying to implement the RSS feed plugin provided by Christoffer von Sabsay
(http://world.episerver.com/Articles/Items/How-dynamic-content-can-be-used-to-create-a-more-flexible-web-site/).

When trying to test this feature I get the error shown below. I've tried to change the control added in web.config
serveral times without any luck.
I have tried to follow the solution in:
http://world.episerver.com/Templates/Forum/Pages/Thread.aspx?id=31173&epslanguage=en
as far as possible but with no luck.

My current registration is :

<

 

add description="Displays a list of items from an external RSS source" name="RSS Feed" type="DynamicContentExample.RSSFeed, EPi247.Publisering.Templates"/>

where "DynamicContentExample.RssFeed" is the path for the Guiplugin and "EPi247.Publisering.Templates is the name of the dll where the code is implemented.

Could you post the code you're using (everything inside RSSFeed.cs).

The code is the orginale code provided in the example.
Since last time I've managed to make it work in on solution based on a orginale Episerver CMS 5.2 installation
on IIS7, but my customer installation is configured for IIS 6 and I use a customer modified web.config.
The solution might be here.
I have to figure out how to make dynimic content run on IIS 6.
My aim is to merge the old customer solution with a brand new Episerver CMS 5.2 installation because the old site have been upgraded 
from previous versions in the past.
Here is the code:
using System;
using System.Web.UI;
using EPiServer;
using EPiServer.Core;
using EPiServer.DynamicContent;
using EPiServer.PlugIn;

namespace DynamicContentExample
{
    [GuiPlugIn(UrlFromUi = "/RSSFeedSettings.ascx", Area = PlugInArea.DynamicContent)]
    public class RSSFeed : IDynamicContent
    {
        public string RssUrl { get; set; }
        public int MaxCount { get; set; }
        public int CacheDuration { get; set; }

        public string Render(PageBase hostPage)
        {
            throw new NotImplementedException();
        }

        public Control GetControl(PageBase hostPage)
        {
            var rssControl = (RSSFeedControl)hostPage.LoadControl("~/RSSFeedControl.ascx");
            rssControl.RssUrl = RssUrl;
            rssControl.MaxCount = MaxCount;
            rssControl.CacheDuration = CacheDuration;
            return rssControl;
        }

        public string State
        {
            get { return RssUrl+"|"+MaxCount+"|"+CacheDuration; }
            set { 
                  string[] values = value.Split('|');
                    if (values.Length==3)
                    {
                        RssUrl = values[0];
                        MaxCount = Int32.Parse(values[1]);
                        CacheDuration = Int32.Parse(values[2]);
                    }
            }
        }

        public bool RendersWithControl
        {
            get { return true; }
        }

        public PropertyDataCollection Properties
        {
            get { throw new NotImplementedException(); }
        }
    }
}
