IndexOutOfRangeException when adding new rows

[Sebastian]

Hi,
when I am using an observable collection of the following class as ItemsSource for the datagrid I get an exception when  I add a new Row (via UI, ShowInsertRow is enabled) and the row is commited.

ArgumentOutOfRangeException: "Specified argument was out of the range of valid values. Parameter name: index".
Source: "Telerik.Windows.Data"
Stacktrace: "bei Telerik.Windows.Data.QueryableCollectionView.GetItemAt(Int32 index) in c:\TB\102\WPF_Scrum\Release_WPF_40\Sources\Development\Core\Data\Collections\QueryableCollectionView.cs:Zeile 1766."
File Version of Telerik.Windows.Controls.GridView.dll is 2011.2.712.40.

This happens only when binding a list of ParameterView. ViewModelBase just implements INotifyPropertyChanged.

public class ParameterView : ViewModelBase<ParameterView>
{
    private string _name;
    public string Name
    {
        get { return _name; }
        set { _name = value; Notify(x => x.Name);}
    }

    private string _value;
    public string Value
    {
        get { return _value; }
        set { _value = value; Notify(x => x.Value); }
    }

    public ParameterView() : this(string.Empty,string.Empty)
    {
    }

    public ParameterView(string name, string value)
    {
        Name = name;
        Value = value;
    }

    public override string ToString()
    {
        return string.Format("Name: {0}, Value: {1}", _name, _value);
    }

    public bool Equals(ParameterView other)
    {
        if (ReferenceEquals(null, other)) return false;
        if (ReferenceEquals(this, other)) return true;
        return Equals(other._name, _name);
    }

    public override bool Equals(object obj)
    {
        if (ReferenceEquals(null, obj)) return false;
        if (ReferenceEquals(this, obj)) return true;
        if (obj.GetType() != typeof(ParameterView)) return false;
        return Equals((ParameterView)obj);
    }

    public override int GetHashCode()
    {
        unchecked
        {
            return ((_name != null ? _name.GetHashCode() : 0) * 397) ^ (_value != null ? _value.GetHashCode() : 0);
        }
    }
}

Hello Sebastian,

 May you please check whether you are reproducing the problem with the binaries from the latest internal build?

Kind regards,
