Listing a News provider in the backend tab bar

    Hi,
    in the website I'm customizing at the moment I have created a second provider for News content, which some additinal metafields and a custom editor page. In the backend I'd like to list it in the tab bar as if it were a separate module though, rather than listing it in the News providers box. Is it possible and which is the best way to do this? I looked into setting up a simple wrapper module which would use the News module classes and give it a different default provider but I'm not sure what I should inherit/override. I tried this:

    public class MyModule : NewsModule
    {
        public override string Name
        {
            get { return "MyModule"; }
        }
     
        public override string Title
        {
            get { return "MyModule"; }
        }
     
        public MyModule()
            : base()
        { }
    }

    And added the required entries to web.config:

    <sectionGroup name="telerik">
        <section name="myModule" type="Telerik.News.Configuration.SectionHandler, Telerik.News" requirePermission="false"/>
    </sectionGroup>
     
    <modules>
        .........
        <add type="MyDll.Data.MyModule, MyDll.Data" />
    </modules>
     
    <metaFields>
        .........
        <add key="MyModule.Title" valueType="ShortText" visible="True" searchable="True" sortable="True" defaultValue=""/>
        .........
    </metaFields>
     
    <providers>
        .........
        <add name="MyModule" urlRewriteFormat="[Publication_Date]/[Title].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="False" defaultMetaField="Title" securityProviderName="" allowVersioning="True" applicationName="/ExtendedNews" versioningProviderName="" commentsModeration="true" connectionStringName="GenericContentConnection" type="MyDll.Data.MyModule, MyDll.Data" allowWorkflow="true"/>
    </providers>
     
    <myModule defaultGenericProvider="myProvider">
          <genericContentProviders>
            <add providerName="myProvider" publicationDateField="Publication_Date" expirationDateField="Expiration_Date" thumbnailUrlField="Thumbnail" urlRewriteFormat="[Publication_Date]/[Title].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_"/>
        </genericContentProviders>
    </myModule>

    But I get an error in the SF log:

    Hi Alessio S.,

    You should implement IIndexingSupportModule, IRssProviderModule in your custom class


    #region IIndexingSupportModule Members
      
       
    IServiceClientInfo[] IIndexingSupportModule.GetSeviceClients()
        {
            return new IServiceClientInfo[]
                {
                    new IndexingServiceClientInfo("NewsCustomIndex"
                        , typeof(NewsIndexProvider)
                        , typeof(NewsIndexSettingsControl).FullName
                        , typeof(NewsIndexViewControl).FullName
                        , "NewsCustomIndexProvider"
                        )
                };
        }
      
          
        #endregion
      
        #region IRssProviderModule Members
      
        RssProviderInfo[] IRssProviderModule.GetRssProviders()
        {
            return new RssProviderInfo[] { new RssProviderInfo(MyModule.ModuleName + " Rss Provider",
                    typeof(Telerik.News.Rss.RssChannelProvider).FullName + ", " + typeof(Telerik.News.Rss.RssChannelProvider).Assembly.FullName,
                new Dictionary<string, string>(),
                typeof(RssSettingsControl).FullName + ", " + typeof(Telerik.News.Rss.RssChannelProvider).Assembly.FullName,
                typeof(RssViewControl).FullName + ", " + typeof(Telerik.News.Rss.RssChannelProvider).Assembly.FullName)
                };
        }
      
      
        #endregion
        internal const string ModuleName = "NewsModuleCustom";
