It already is.
I have a code like this:
Request request = builder.sendRequest(null, new RequestCallback() {
public void onError(Request request, Throwable exception) {
// Couldn't connect to server (could be timeout, SOP
violation, etc.)
}
@Override
public void onResponseReceived(Request request,
Response response)
{
}
In onResponseReceived I parse JSON which I received and populate a
variable which is member of class and call another method, for
populate some table. Another method get the variable (which I
populated) - but it is empty until I call Window.alert("anything").
After alert the variable is populated.
