The animation is raised in general via a UI event. But in a UI element, we can
attach other events such as an event for Dyanmic UI, or an event for invoking a
business action. And the animation events must be executed first. Once all
animation events get done, other events can be fired. 

We need to add a such solution to handle two kinds of events automatically :
First animation events and then others.
