Hello,
I've tried a little trick today, because I still belive the browser
downloads code he does not need before he actually needs it.
I placed this:
Window.Location.reload();
inside my *UserViewImpl, *so it would reload after the login.
The problem is that when the application starts with the *LoginViewImpl *the
page refreshes every second. So I'm not even in the UserViewImpl, so I
didn't log in, and the page gets the code from the UserViewImpl and starts
refreshing.
The thing is I've used code splitting in my application like this:
*Login Button*
loginButton.setHTML(LoginFormConstants.LOGIN_BUTTON);
loginButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
final String username = usernameBox.getText();
final String password = passwordBox.getText();
// Is this good code splitting ?
GWT.runAsync(new RunAsyncCallback() {
@Override
public void onSuccess() {
performUserConnection(username, password);
}
@Override
public void onFailure(Throwable reason) {
// TODO Auto-generated method stub
}
});
}
});
and *performUserConnection()*
private static void performUserConnection(String username, String password)
{
DBConnectionAsync rpcService = (DBConnectionAsync)
GWT.create(DBConnection.class);
ServiceDefTarget target = (ServiceDefTarget) rpcService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "DBConnectionImpl";
target.setServiceEntryPoint(moduleRelativeURL);
rpcService.authenticateUser(username, password, new AsyncCallback<User>() {
@Override
public void onSuccess(User user) {
if (user.getType().equals("User")) {
String username = user.getUsername();
presenter.goTo(new UserPlace(username));
} else if (user.getType().equals("Admin")) {
String username = user.getUsername();
presenter.goTo(new AdminPlace(username));
}
}
@Override
public void onFailure(Throwable caught) {
DialogBox dialogBox = createDialogBox();
dialogBox.setGlassEnabled(true);
dialogBox.setAnimationEnabled(true);
dialogBox.center();
dialogBox.show();
}
});
}
So the page should wait to see if connection was successful, and then
download the code, right ? Why isn't this happening ?
Thanks in advance
