custom filter template losing binding

[Piotr]

For FilteringControl we written template. Main idea was to reverse order of items in ValueList. 
Right now i faced with issue. 
First time when i open filter by clicking filtering icon and select/deselect one position filtering works. So far so good. 
I click outside filter window (control), it lose focus and hide. 
Then open it again, repeat operation. Filtering not works. 
But only on DistinctValuesList. Range filters works. 

I presume source of issue is binding to IsActive property. 
Below FilteringControl template code:

<ControlTemplate TargetType="telerik:FilteringControl">
  <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1" Margin="{TemplateBinding Margin}">
    <Border BorderBrush="{StaticResource ControlInnerBorder}" BorderThickness="1" Background="{TemplateBinding Background}">
      <Grid>
        <StackPanel HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" MaxWidth="350" Margin="{TemplateBinding Padding}" MinWidth="200" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
          <StackPanel x:Name="PART_DistinctFilter" Visibility="{TemplateBinding DistinctFiltersVisibility}">
            <CheckBox x:Name="PART_SelectAllCheckBox" IsChecked="{Binding SelectAll, Mode=TwoWay}" Margin="0,2" telerik:LocalizationManager.ResourceKey="GridViewFilterSelectAll" telerik:StyleManager.Theme="{StaticResource Theme2}"/>
            <ListBox x:Name="PART_DistinctValuesList" ScrollViewer.HorizontalScrollBarVisibility="Auto" ItemsSource="{Binding DistinctValues, Converter={StaticResource reverseItemsSourceConverter}}" ItemContainerStyle="{StaticResource DistinctValueListBoxItemStyle}" SelectionMode="Multiple" telerik:StyleManager.Theme="{StaticResource Theme2}">
              <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                  <VirtualizingStackPanel MaxHeight="242"/>
                </ItemsPanelTemplate>
              </ListBox.ItemsPanel>
              <ListBox.ItemTemplate>
                <DataTemplate>
                  <CheckBox Content="{Binding ConvertedValue, Converter={StaticResource DistinctValueConverter}}" IsChecked="{Binding IsActive, Mode=TwoWay}" telerik:StyleManager.Theme="{StaticResource Theme2}" VerticalContentAlignment="Center"/>
                </DataTemplate>
              </ListBox.ItemTemplate>
            </ListBox>
          </StackPanel>
          <StackPanel Margin="0,2" Visibility="{TemplateBinding FieldFiltersVisibility}">
            <TextBlock Margin="0,2,0,0" telerik:LocalizationManager.ResourceKey="GridViewFilterShowRowsWithValueThat"/>
            <telerik:RadComboBox x:Name="PART_Filter1ComboBox" ItemTemplate="{StaticResource ActionTemplate}" ItemsSource="{Binding AvailableActions}" Margin="0,2,0,2" SelectedItem="{Binding Filter1.Operator, Mode=TwoWay}" telerik:StyleManager.Theme="{StaticResource Theme2}"/>
            <ContentControl x:Name="PART_Filter1ContentControl" DataContext="{Binding Filter1}" HorizontalContentAlignment="Stretch" IsEnabled="{Binding Operator, Converter={StaticResource FilterOperatorToFilterEditorIsEnabledConverter}}" Margin="0, 2" VerticalContentAlignment="Stretch"/>
            <telerik:RadComboBox x:Name="PART_LogicalOperatorsComboBox" ItemTemplate="{StaticResource LogicalOperatorTemplate}" ItemsSource="{Binding LogicalOperators}" Margin="0,2" SelectedItem="{Binding FieldFilterLogicalOperator, Mode=TwoWay}" telerik:StyleManager.Theme="{StaticResource Theme2}"/>

          </Grid>

        <telerik:RadButton x:Name="PART_FilterCloseButton" HorizontalAlignment="Right" Height="13" Margin="{TemplateBinding Padding}" telerik:StyleManager.Theme="{StaticResource Theme2}" VerticalAlignment="Top" Width="13">

        </telerik:RadButton>
      </Grid>
    </Border>
  </Border>
</ControlTemplate>

and usage:

<telerik:GridViewDataColumn DataMemberBinding="{Binding DealDate.Date}" Header="Deal Date" Width="Auto" IsFilterable="True" TextAlignment="Right" IsSortable="True" FilteringControlStyle="{StaticResource ReverseOrderOfItems_FilterControlStyle}">
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Path=DealDate, StringFormat=dd/MM/yyyy}"></TextBlock>
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

Hello,

I have tried to reproduce the problem using the pasted ControlTemplate. At first I were not able to run it due to the missing resources. For example the: reverseItemsSourceConverter. That is why I deleted it. Then I run it (adding the definitions for the other missing resources) and I were not able to reproduce the issue. Do you reproduce it if you remove your additional converter?

Greetings,
