Call
Widget mainMenu = createMenu();
initWidget(mainMenu);
from the onSuccess() method of the RPC after you have set the userInfo
object.
Something like:
rpcService.getUserInfo(username, new AsyncCallback<UserInfo>() {
@Override
public void onSuccess(UserInfo result) {
UserPanel.userInfo = result;
Widget mainMenu = createMenu();
initWidget(mainMenu);
}
@Override
public void onFailure(Throwable caught) {
// Window.alert(caught.getMessage());
}
});
Remember, GWT RPC is asynchronous, so you have to always make sure you
execute dependent code blocks in sequence.
