I have a ToggleButton with its IsChecked property bound to a property using a OneWay binding.

<ToggleButton
    Command="{Binding Path=SomeCommand}"
    IsChecked="{Binding Path=SomeProperty, Mode=OneWay}" />

The SomeCommand toggles the boolean SomeProperty value, and a PropertyChanged event is raised for SomeProperty.

If I change SomeProperty in my viewmodel the ToggleButton depresses correctly. However if I click the ToggleButton the binding seems to get lost and the button no longer gets checked according to the value of SomeProperty. Any ideas on how to fix this problem?
