Returning a NULL object reference error when loading the web application
I'm returning a null object reference when running the inital page. The error occurs in the SavePageState method calling LoadProviders();
the _provider = _providers[section.DefaultProvider]; is returning a null value
I noticed that my section.providers returns a count of 0 from below.
The error occurs at _provider.SavePageState(name,viewstate); (actually error NullReferenceException was unhandled by user code. I see a first and second in the viewstate object the first is Null.
Please note I'm not using the WCF since it was not necessary.
var section = (ViewStateProviderServiceSection) WebConfigurationManager.GetSection("myviewstateSection/viewstateService"); // Load all registered providers _providers = new ViewStateProviderCollection(); ProvidersHelper.InstantiateProviders (section.Providers, _providers, typeof(ViewStateProviderBase)); // Set _provider to the default provider _provider = _providers[section.DefaultProvider];
