PagebyPageIterator problem with lastPage() method

[GoogleCodeExporter]

Problem if a previous() method is invoked after a call of the lastPage() 
method.

For the moment if the lastPage() is invoked, and if the use must test if 
!it.hasPrevious... not use the it.previous() but it.current()

See the new example of the class :) 

TODO : refactoring the example with external class

Not a bug but a fix when use the iterator, see the example :
http://code.google.com/p/maashaack/source/browse/trunk/AS3/examples/maashaack/sy
stem/data/iterators/examples/PageByPageIteratorExample.as?spec=svn692&r=692

{{{
public function prev():void
{
    var prev:* ;
    if ( !it.hasPrevious())
    {
        prev = it.previous() ;     
    }
    else
    {
        it.lastPage() ;
        prev = it.current() ;
    }
    trace( "> prev:" + prev + " currentPage:" + it.currentPage() + " current:" +
eden.serialize(it.current()) ) ;
}

}}}
