Hello,

Version 5.2.2

I am new to DNN, but I have built a simple IFrame module based on the DNN IFrame, added the module to my website, but when I attempt to add the module to a page I get the following error..

An error has occurred.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Entities.Modules.ModuleController.AddModule(ModuleInfo objModule) at DotNetNuke.UI.ControlPanels.ControlPanelBase.AddNewModule(String title, Int32 desktopModuleId, String paneName, Int32 position, ViewPermissionType permissionType, String align) at DotNetNuke.UI.ControlPanels.IconBar.AddModule_Click(Object sender, EventArgs e) in C:\Business\TSS\Development\Net2005\DDN\v050202\VMSDNN\Admin\ControlPanel\IconBar.ascx.vb:line 500 --- End of inner exception stack trace ---

I have tried several things to get around the issue, one attempt was creating the module definition through DNN, adding a new source code file during the installation,  I then added the module to a page, which worked, but when I created a manifest file, uninstalled the module, then reinstalled using the unaltered manifest file with the newly created source file, which worked, now throws the same erorr.

Through debug, the failure occurs when calling AddModule.

Can someone direct me on what to try next.

Thanks in advance for your response.

MR 

Mitchel,

Thanks for the quick response. 

Based on your reply, I started playing with the Edit Module Control area and noticed that on several other modules, the View control was not defined with a key.  I removed the word I entered for the main View control in my module and I was able to add the module to a page.  I am sure this is mentioned somewhere, but I missed it. 

Thanks for the guidance.
