com.codename1.ui.Container.Anim.animate() throwing java.lang.ArrayIndexOutOfBoundsException

[GoogleCodeExporter]

com.codename1.ui.Container.Anim.animate() throws an 
java.lang.ArrayIndexOutOfBoundsException when a component is added to the 
animated Container whilst an animation is already registered.
The XXX is thrown when it accesses the motions array for a component which did 
not yet exist when the animation was registered. 

it does this continuously because the animation never finishes because of the 
exception. 

I suggest that the animate() method should be wrapped in a try-catch block and 
that the animation is cancelled in case of an exception.

I also suggest that the animate() method only iterates over as many entries as 
the motions array contains - use motions.length instead of componentCount. 
Either this or - another solution was to integrate the new component(s) in the 
animation by extending the animations arrays.

See this example code. In the real world one obvoiusly does not cause the bug 
intentionally, but how should one know whether an animation ist still in 
progress before adding a component?

Please do something about it. My app is crashing and I do not know what to do 
to prevent it.
