DATA BINDING - Validation object (Rule) never called.

My validation rule is instantiated, but Validate is never called on PropertyChanged trigger.

<TextBox.Text>

<Binding Path="Tag" Source="{StaticResource ExposureTime}" Converter="{StaticResource StringToNumConverter}" UpdateSourceTrigger="PropertyChanged">

<Binding.ValidationRules>

<c:ExposureValidation/>

</Binding.ValidationRules>

</Binding>

</TextBox.Text>

The Binding system is pretty much blackbox, so there isn't much to go on.

The validation binding is being lost when the binding is RE-set in code.
