 Does anybody have an example of implementing AsyncProxy to dynamically
 load a class via the underlying runAsync?

 Basically I use the snippet of code in the AsyncProxy javadoc, but at
 compilation time I get the following error:

   interface IFoo {
     void doSomething(int a, int b);
     void anotherMethod(Object o);
   }
   class FooImpl implements IFoo {
     @Override
     public void anotherMethod(Object o) {
     }
     @Override
     public void doSomething(int a, int b) {
     }
   }

   @ConcreteType(FooImpl.class)
   interface FooProxy extends AsyncProxyIFoo, IFoo {}

   class UserOfIFoo {
     private IFoo foo = GWT.create(FooProxy.class);

     void makeTrouble() {
       // This first call triggers a runAsync load
       foo.doSomething(1, 2);

       // and this second will replayed after the call to doSomething()
       foo.anotherMethod(A string);
     }
   }

 What does it mean FooImpl to be static? I mean, this is the example
 in the javadoc! I don;t see any special instructions for using
 AsyncProxy.

 Thanks

GWT 1.7 - GWT 2.0 - compiled size significantly increased

[swxoz]

Hi,
After migration form GWT 1.7 to 2.0.1 we've noticed increased size of
result .cache. file.

OBFUSCATED size incresed from 500kB - 1 MB - almost twice.

GWT 2.0 introduced turned on by default stack traces in web mode

http://code.google.com/p/google-web-toolkit/wiki/WebModeExceptions

You can turn it of by setting in module xml (it seems reasonable for
production use).

set-property name=compiler.emulatedStack value=false /


Greeting
Greg Bugiel
