I have a Flex Application that has a TabNavigator. Each tab contains a moduleLoader that loads a corresponding Module.
On some of these modules, I have a basic Form with Validators connected to it. I want to be able to make sure that the form values are valid before the user navigates away from the currently selected tab by clicking a new tab. In other words, I want the Validator to fire when the user clicks on a new tab and if there are any invalid values I want to prompt the user to fix them and stop the event propogation so the TabNavigator stays on the current tab. How can I cancel the TabNavigator change?
