We are using two-way bindings with a delay of 1 second in a few places in our UI and these work fine. However when a user enters some text and then shortly after that the UI that has the TextBox gets removed, before the delay of the binding, we are getting an exception.

Example XAML:
<TextBox Text="{Binding Value, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay, Delay=1000}" />

Exception:
Noesis::BindingExpression::UpdateSourceInternal(const void *) BindingExpression.cpp:1353
Noesis::BindingExpression::BeforeSet::<lambda_0>::operator()() BindingExpression.cpp:309
Noesis::Timer::Update(double) Timer.cpp:70
