I had developed a series of Modules for use in  DNN 4.0.0 oringally and they have upgraded fine until latest 4.8.2 upgrade. The modules View/Display is aok but the Edit now throws up an error:

DotNetNuke.Services.Exceptions.ModuleLoadException: Object must implement IConvertible. ---> System.InvalidCastException: Object must implement IConvertible. at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) at System.Convert.ChangeType(Object value, Type conversionType) at DotNetNuke.Common.Utilities.CBO.HydrateObject(Object objObject, IDataReader dr) at DotNetNuke.Common.Utilities.CBO.CreateObject(Type objType, IDataReader dr) at DotNetNuke.Common.Utilities.CBO.FillObject(IDataReader dr, Type objType, Boolean ManageDataReader) at DotNetNuke.Common.Utilities.CBO.FillObject(IDataReader dr, Type objType) at eWiz.Modules.Course.courseController.GetCourse(Int32 CourseId) at eWiz.Modules.Course.EditCourse.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

Has anyone experienced the same or can point me in the same direction as I will need to update my modules accordingly.

Thanks
