Hello,

I am attempting to access the settings page that I created as part of the module I am working on. When I build the project and run it, I am having the following problem:

The project builds fine, but when I attempt to access the settings page I get the following message:

Object reference not set to an instance of an object.

When I debug the code, I find that the error is raised when the DNN core code attempts to retrieve a handle of the control:

In admin\Modules\ModuleSettings.ascx.vb:

…

If Not [Module] Is Nothing Then

                TabModuleId = [Module].TabModuleID

 

                'get Settings Control

                objModuleControlInfo = ModuleControlController.GetModuleControlByControlKey("Settings", [Module].ModuleDefID)

 

                If objModuleControlInfo IsNot Nothing Then

 

'
' The error is raised here.
'
                    _Control = ControlUtilities.LoadControl(Of Control)(Me.Page, objModuleControlInfo.ControlSrc)

'
'
'
                    Dim SettingsControl As ISettingsControl = TryCast(_Control, ISettingsControl)

                    If SettingsControl IsNot Nothing Then

                        'Set ID

                        _Control.ID = System.IO.Path.GetFileNameWithoutExtension(objModuleControlInfo.ControlSrc).Replace("."c, "-"c)

 

                        ' add module settings

                        SettingsControl.ModuleContext.Configuration = [Module]

…

I referenced the settings page correctly via the manifest (dnn) file. below is my code-behind file for my settings page:

 Well, I set the breakpoint to the LoadSettings() subroutine that I have and that subroutine isn't even called. Also, I do have that code within a Try block that is never called.

This error that I am referring to happens even before my code is called.

Thank you for your time.
