I am going to get this page working if it 's the last thing i do!!!

So NOW I put my code in the module, via Visual Studio, to do what I want it to do.  I saved it and now I get the error.  I'll keep looking, but if any of you experienced folk can point me in the appropriate direction, I'd appreciate it!

Thanks!

Have you found any solution to this problem?
It seems to me that the framework executes the GetTabModules stored procedure and tries to build up a dictionary with ModuleInfo's.
Unfortunally, GetTabModules not onlyt returns the modules, but also the controls per module.

I've got a module with multiple controls, so GetTabModules retrieves multiple records for one module.
Because the ModuleId is used as the key in the dictionary it fails.....
Still no solution though.

From GetTabModules:

//Get modules form Database
modules = FillModuleInfoDictionary(DataProvider.Instance().GetTabModules(TabId));

From FillModuleInfoDictionary:

 private Dictionary<int, ModuleInfo> FillModuleInfoDictionary(IDataReader dr)
        {
            Dictionary<int, ModuleInfo> dic = new Dictionary<int, ModuleInfo>();
            try
            {
                while (dr.Read())
                {
                    // fill business object
                    ModuleInfo obj = FillModuleInfo(dr, false, true);
                    // add to dictionary
                    dic.Add(obj.ModuleID, obj);
                }

I'm having the the same problem. I'm runing DNN 4.9.4. Not sure it's caused by the recent upgrade or it happened before the upgrade.
