Hey !
Please don't post multiple times your questions (http://
groups.google.com/group/Google-Web-Toolkit/msg/0675da9d966c77d7), be
patient and maybe somebody will reply ;)
So about your popup thing, why use JSNI when you can just do
public void onModuleLoad() {
Window.alert("This is a GWT function")
}
Maybe you're simplifying your code to show us what you're trying to
accomplish, but if you really just want an alert, don't go the JSNI
way.
