Converting an app to use generics is a pain, but once you've done it, it does
make a lot of sense. It cuts down on a lot of casting and helps keep things
type-safe. It's also a reminder about exactly what is supposed to be in each
collection.
It's well worth taking the time to do the
but in my applicaiton:
public Map java.lang.String,java.util.List filterStates = new HashMap();
the value of filterStates is java.util.List, I can't specify the type for
it, for in my app, this value is Object, it might be String, and other
self-defined class/object, how to handle this?

twu question:
1. what difference?
public interface State {}
and
public class State implements Serializable {
MyType type;
String string;
FOO foo;
BAR bar;
}
2. what difference between Serializable and IsSerializable?

It's just a matter of taste, of which one you prefer.
When I upgrade GWT version from 1.4.60 to 1.5.3 in my project, I run at
hosted mode, I found many errors like below:
[WARN] In order to produce smaller client-side code, 'Object' is not
allowed; consider using a more specific type
Although I can see the pages at hosted mode, but no data can't
GWT 1.5 introduced generics. Where before you might have had an RPC argument of ArrayList
bar, you will now have ArrayListFoo bar
See here:

and here:
It's a WARN no an error. You can safely ignore it.

thanks Juan Pablo Gardella, you said it is a WARN no an error, but why can'tno
data be retrieved from server in hosted mode, and in web mode it work fine?
I check my code, it should be ok, only there is the WARN message in hosted
mode.
