Exception: Object of type 'Csla.Rules.AddObjectAuthorizationRulesContext' cannot be converted to type 'Csla.ApplicationContext'.

CSLA 8 get the error message when calling HasPermission. Here's the HasPermissioin method being called in CSLA:

//
// Summary:
// Checks per-type authorization rules.
//
// Parameters:
// applicationContext:
//
// action:
// Authorization action.
//
// objectType:
// Type of business object.
public static bool HasPermission(ApplicationContext applicationContext, AuthorizationActions action, Type objectType)
{
if (applicationContext == null)
{
throw new ArgumentNullException("applicationContext");
}

Here's the calling function from the business object:

public static bool CanGetObject(ApplicationContext appContext)
{
return Csla.Rules.BusinessRules.HasPermission(appContext, Csla.Rules.AuthorizationActions.GetObject, typeof(AddressAddressTypeList));
}

The method signatures match and ApplicationContext is valid. What could be happening to get the exception:

Object of type 'Csla.Rules.AddObjectAuthorizationRulesContext' cannot be converted to type 'Csla.ApplicationContext'.

Call Stack only shows what I've posted. Help! :-)
