Hello Fred,
something like:
if(! LoginService.checkLogin(user, password) ) {
displayError();
}
will not be possible with GWT, I guess?
Furthermore, I do not understand this part:
void showContact(final Contact contact) {
service.execute(new GetDetails(contact.getDetailIds()),
new GotDetails() {
public void got(ArrayList<ContactDetail> details) {
renderContact(contact);
renderDetails(details);
}
});
}
Where do I have to do the actual RPC call, let's say, query a remote
database?
