title: AEM 6.1 Touch UI Dialog - invoke dialog validation event manually
body: <p>I have some callback on dialog-submited event and I want to find out way to guarantee that dialog will be submitted after my callback (the validation after my callback can inhibit me). Can I pre validate manually whole dialog (every widget) if I'm not aware how much widgets exist on dialog. Maybe there is something in order to invoke this validation?</p>
