I have a confirm mixin that I use. I can added it to a <t:submit/> and it
works fine. When I try to use it with a <t:LinkSubmit/> the confirmation
box is displayed but the cancel button doesn't stop the submit.
<t:Submit t:id="clear" value="Clear"
t:mixins="Confirm" t:message="Are you sure you want to remove all
entered serial numbers without saving?" />
Dose anyone know how to make this work with a LinkSubmit or know of another
way to do this?
