DFWP - Column 'Content Type ID' does not exist

Hi,

ich hab ein erweitertes DFWP erstellt und will mir Daten aus einer Liste anzeigen lassen.

Dabei erhalte ich jedoch immer wieder diesen Fehler:

Error while executing web part: System.ArgumentException: Column 'Content Type ID' does not exist. It may have been deleted by another user.  /Lists/MyList   
 at Microsoft.SharePoint.SPFieldCollection.GetFieldByInternalName(String strName, Boolean bThrowException)

Weis einer warum dieser Fehler auftritt? Ich referenze weder im XSLT-Template noch in meinen DataFields auf dieses Feld...

Das Projekt besteht aus:

• ContentType
• ListTemplate / Definition
• ListInstance
• DFWP welches auf diese Instanz verweist

Also die Liste beinhaltet als einzigen ContentType meinen selbst erstellten!

Das mysteriöse:

als ich das ganze mit dem Designer entwickelt und getestet hab, ging es...

Nach der eigenentwicklung + deployment gings nicht.

In der OnInit erstell ich die DataConnection:

                this.ParameterBindings = BuildParameterBindings();
                this.DataSources.Add(BuildDataSource());
                this.DataFields = "@Title,Title;@MyContent,MyContent;"+
                                  "@Author,Created By;@ID,ID;" +
                                  "@Modified,Modified;@Created,Created;@Editor,Modified By;"+
                                  "@Attachments,Attachments;";
                this.Xsl = BuildXsl();
                this.DataBind();

        private string BuildParameterBindings()
        {
            StringBuilder paramBind = new StringBuilder("<ParameterBindings>");
            paramBind.Append("<ParameterBinding Name=\"dvt_apos\" Location=\"Postback;Connection\"/>");
            paramBind.Append("<ParameterBinding Name=\"ManualRefresh\" Location=\"WPProperty[ManualRefresh]\"/>");
            paramBind.Append("<ParameterBinding Name=\"UserID\" Location=\"CAMLVariable\" DefaultValue=\"CurrentUserName\"/>");
            paramBind.Append("<ParameterBinding Name=\"Today\" Location=\"CAMLVariable\" DefaultValue=\"CurrentDate\"/>");
            paramBind.Append("<ParameterBinding Name=\"dvt_firstrow\" Location=\"Postback;Connection\"/>");
            paramBind.Append("<ParameterBinding Name=\"dvt_nextpagedata\" Location=\"Postback;Connection\"/>");
            paramBind.Append("</ParameterBindings>");

            return paramBind.ToString();
        }

        private AggregateDataSource BuildDataSource()
        {
            StringBuilder dataSource = new StringBuilder();
            AggregateDataSource ads = new AggregateDataSource();
            ads.SeparateRoot = "true";           

            SPDataSource spdsPosts = new SPDataSource();
            SPDataSource spdsComments = new SPDataSource();
            Parameter p = new Parameter();
            Parameter c = new Parameter();
            p.Name = "ListName";
            p.DefaultValue = "MyList";

            spdsPosts.SelectCommand = "<View><Query><OrderBy><FieldRef Name=\"Created\" Ascending=\"FALSE\"/></OrderBy></Query></View>";
            spdsPosts.DataSourceMode = SPDataSourceMode.List;
            spdsPosts.SelectParameters.Add(p);
            spdsPosts.UpdateParameters.Add(p);
            spdsPosts.InsertParameters.Add(p);
            spdsPosts.DeleteParameters.Add(p);

            dataSource.AppendLine("<concat name=\"data source\">");
                dataSource.AppendLine("<datasource name=\"MyList\" id=\"0\" Type=\"SPList\"/>");
            dataSource.AppendLine("</concat>");

            ads.Sources.Add(spdsPosts);
            ads.Aggregate = dataSource.ToString();

            return ads;
        }
