Warning about AxPageBase.URL
The property AxPageBase.URL was renamed (conform to Microsoft Coding Conventions) to AxPageBase.Url. The old property remains in the class, but is deprecated and will not be supported in the future versions. Please change .URL to .Url in your code to avoid warning, thrown by a compiler.
The method CommonUI.FillUsersDropDownList was extended and has now the second parameter. It controls, if the user lists should be loaded from Management System or Live System. Pass Systems.ManagementSystem to retain the old behaviour.
