I have a case where I get a binding path error. However, some of the bindings still work while others don't. I have the following classes (copy/pasted only the relevant bits) :
Code behind :
class RSSManager : BaseViewModel
{
#region Resources
private Platforms _platformsList;
public Platforms PlatformsList
{
get { return _platformsList; }
set
{
_platformsList = value;
NotifyPropertyChanged("PlatformsList");
}
}
private List<IActivity> _mainActivitiesList = new List<IActivity>();
public List<IActivity> MainActivitiesList
{
get { return _mainActivitiesList; }
set
{
_mainActivitiesList = value;
NotifyPropertyChanged("MainActivitiesList");
}
}
private ObservableCollection<IActivity> _activitiesList = new ObservableCollection<IActivity>();
public ObservableCollection<IActivity> ActivitiesList
{
get { return _activitiesList; }
set
{
_activitiesList = value;
NotifyPropertyChanged("ActivitiesList");
}
}
private ObservableCollection<IActivity> _alertsList = new ObservableCollection<IActivity>();
public ObservableCollection<IActivity> AlertsList
{
get { return _alertsList; }
set
{
_alertsList = value;
NotifyPropertyChanged("AlertsList");
}
}
private ObservableCollection<IActivity> _invasionsList = new ObservableCollection<IActivity>();
public ObservableCollection<IActivity> InvasionsList
{
get { return _invasionsList; }
set
{
_invasionsList = value;
NotifyPropertyChanged("InvasionsList");
}
}
private ObservableCollection<IActivity> _outbreaksList = new ObservableCollection<IActivity>();
public ObservableCollection<IActivity> OutbreaksList
{
get { return _outbreaksList; }
set
{
_outbreaksList = value;
NotifyPropertyChanged("OutbreaksList");
}
}
private ObservableCollection<IActivity> _doneList = new ObservableCollection<IActivity>();
public ObservableCollection<IActivity> DoneList
{
get { return _doneList; }
set
{
_doneList = value;
NotifyPropertyChanged("DoneList");
}
}
#endregion
}
public partial class Activities : Page, IOptions
{
Options.OptionsActivities _options = new Options.OptionsActivities();
RSSManager _manager = new RSSManager();
public Activities()
{
InitVars();
InitializeComponent();
DataContext = _manager;
UpdateCheckBoxes();
UpdateTabsHeaders();
}

The errors :

I haven't yet gotten to the part of factoring templates, but I don't think that is the issue here.
As stated, even though I get the errors, the program is showing what I want. However, the bindings I added next are not working at all with the output giving the same error types (wrong path). What am I doing wrong here?
