Issy1138,

have you created a transition that from your startState to you
destinationState? A transition can define exactly what you would like to
happen during a state change.



<mx:transitions>
<mx:Transition fromState="startState" toState="destinationState">
<mx:Fade target="{yourComponent}" alphaFrom="1.0" alphaTo="1.0" />
</mx:Transition>
</mx:transitions>
