Old components never die; they just fade away.
This show is all about the new Fade effect in Flex 4, which allows you to fade objects (components, graphic objects, and anything else with an
alpha property) in and out. This effect exists in Flex 3 already, although it got a little reworking in Flex 4 to add useful functionality. For one thing, it uses the ability of the Animate effect to target arbitrary target objects (useful in the world of Flex 4, where we may have graphical objects in our application instead of just UIComponents). But also, the new Fade effect has a little more intelligence built into it that helps it figure out when you want to automatically fade things in and out, based on the value of related properties like visibility and whether the object is becoming parented or unparented between states of a transition.
