Hi,
I'm trying to create a new module in DNN6 using Christoc's templates. So, I have VS2008, MSBuild,  the template and DNN 6.0.2 CE Install Package installed as directed in the wiki. On the portal I've installed a skin which is not using the new DDRMenu. The problem arises when I buld the module. Somehow it blows the DDRMenu (see error below) even if I'm not using it in the skin. After that the portal is unusable. I've tried to downgrade to 6.0.1 with the same result. Then, tried to upgrade the project to Framework 4 (even if in the wiki it says v2). I doubt that has something with the machine as I'm sucesfully developing modules for DNN5 on it (Windows 7 x64 + IIS 7.5 + SQL Server 2008R2).

The error I'm getting:
An error has occurred.DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Web.DDRMenu.DDRMenuControl.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

Do you have DDR referenced in the module?

I'll try that, but first I have to reinstall the development environmet because the portal throws the error even when I delete the dll from the bin folder and the entire module from the DesktopModules folder. I even believe that something gets messed up in the IIS configuration as I've tried to restore the database to the point before compiling the module and the portal still throws the error.

OK. I've reinstalled the environment from scratch and referrenced DDR. Now the portal does not crash. But, now i'm getting 
 Error: Katalog is currently unavailable.DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for 'kr.Modules.Katalog.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'kr.Modules.Katalog.DataProvider' threw an exception. ---> System.ArgumentNullException: Value cannot be null.

I've searched through the forum and most of the posts claim that
objProvider = CType(Framework.Reflection.CreateObject("data", "kr.Modules.Katalog.Data", "kr.Modules.Katalog"), DataProvider)
should solve the problem. Well, it does not.

The Namespace and Assembly name are set to: kr.Modules.Katalog.

What am I doing wrong?

Hi Chris,
Please disregard my previous posts. Well, it's true that I've blown DNN with your templates but finally I've found the reason. As I'm developing (maintanance only) some modules for DNN5 and programming the new ones in DNN6  I have two different installations accordingly http://dnndev and http://dnndev6. For the template to work (compile) correctly I had to modify the source files and references in the source files to dnndev6 and after creating the solution (IMPORTANT) I had to change the property Copy Local to False for each DotNetNuke reference in VS. This is the reason I've blown DNN6 - I had the reference to DotNetNuke.Webcontrols from DNN5 (as it was in dnndev/bin folder) and when i compiled the module it copied it over the DNN6 version.

Maybe you could put a note about that on your wiki.
