Hi,
Create the factory instance at the starting of the method similar to below
public void listtest(){
MyFactory fact = GWT.*create*(MyFactory.*class*);
...
}
Use the below code
*points.add(fact.point(o).as());*
* *
*points.add(fact.point(n).as());*
instead of
*points.add(o);*
*points.add(n);*
Thanks
*Govindan*
