wpf - 如何使用 AttachedCommandBehavior 将多个事件绑定到 setter 样式？

Question

我需要将多个命令绑定到 xamdatapresenter 的记录。

<igDP:FieldLayoutSettings.DataRecordPresenterStyle>
    <Style TargetType="{x:Type igDP:DataRecordPresenter}" >
        <Setter Property="HeaderAreaBackground" Value="#FF1E1E1E" />
        <Setter Property="localCommand:CommandBehaviorCollection.Behaviors">
            <Setter.Value>
                <localCommand:BehaviorBindingCollection>
                    <localCommand:BehaviorBinding Event="MouseDoubleClick" 
                                                  Command="{Binding  DataContext.ShowOrderDetailCommand,RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type igDP:XamDataPresenter}}}" 
                                                  CommandParameter="{Binding RelativeSource={RelativeSource Self}}"/>
                    <localCommand:BehaviorBinding Event="PreviewMouseUp" 
                                                  Command="{Binding  DataContext.ShowSecurityDetailCommand,RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type igDP:XamDataPresenter}}}" 
                                                  CommandParameter="{Binding RelativeSource={RelativeSource Self}}"/>
                </localCommand:BehaviorBindingCollection>
            </Setter.Value>
        </Setter>
    </Style>
</igDP:FieldLayoutSettings.DataRecordPresenterStyle>

但是在运行项目时出现错误：

ArgumentNullException：值不能为空。参数名称：属性

提示localCommand:CommandBehaviorCollection.Behaviors属性为空。我错过了什么？有人有想法吗？
