Enterprise Library 5.0 - Validation - Refresh

Question

I am using the Validation Application Block (VAB) of the Enterprise Library 5.0. All is working well and I get the appropriate messages, but when I navigate to another tab in the tab control and navigate back the validation messages have all disappeared and don't reappear until I change a value to be invalid again.

The application is a WPF application and I am using standard VAB libraries to integrate with the application.

How can I tell the UI to re-evaluate all validation and display the errors?
