sync

allows you to sync two copies of data (all or just a part of it) from one DataCollection to another

source	object	the object that the method is assigned to
filter	function	the filtering function
silent	boolean	if you set the parameter to true, the object won't be repainted after synchronization

Example

//full copy
$$('$combo').getList().data.sync(data);
 
//partial copy          
$$('$combo').getList().data.sync(data, function(){
    this.filter(function(data){
        return data.year > 1994;
    });
});

Pay attention that you need to call the getList() method to access the data collection of Combo and Richselect.
