The"ever engine" occurs

[Google Code Exporter]

When Tweener trying to modify some property, that's value cannot be set the 
tween will not reach the end irrespective of time parameter.

E.g.

public function set val( n:Number ):void
{
_myval = ( _myval + n ) / 2;
}
public function get val():Number
{
return _myval;
}

Tweener.addTween( this , { val : 10 , time : 0.5 } ); //will try to set it 
almost ever, not time!
