WPF - Freezable in a style of a button not inheriting DataContext

[admin]

I am modeling an attached command pattern after the <a href="http://marlongrech.wordpress.com/2008/12/13/attachedcommandbehavior-v2-aka-acb/" rel="nofollow">AttachedCommandBehavior library here</a>. My button looks like this:

<Button>
    <Button.Style>
        <Style TargetType="{x:Type Button}">
            <Setter Property="vms:Attached.Behaviors">
                <Setter.Value>
                    <vms:Behaviors>
                        <vms:Behavior Event="Click" 
                                      Command="{Binding ClickCommand}" />
                    </vms:Behaviors>
                </Setter.Value>
            </Setter>
        </Style>
    </Button.Style>
</Button>

Everything works great, but when the setter on the

Behavior

is executed, the Command is

null

.

Behavior is a

Freezable

, and Behaviors is a

FreezableCollection<Behavior>

. It just doesn't seem to be inheriting the DataContext from the Button.

On the other hand, this works correctly:

<Button>
    <vms:Attached.Behaviors>
        <vms:Behavior Event="Click" Command="{Binding ClickCommand}" />
    </vms:Attached.Behaviors>
</Button>

Unfortunately I can't do it this way, because I need to target generated

ListViewItem

s using

ItemContainerStyle

.

Is there some way to get the DataContext in the Style?
