    message('Page loaded');
}

void cbDemo.say_hello_world() {
    message('First Application', 'Hello World', 'info');
    message('First Application', 'Hello World', 'notice');
    message('First Application', 'Hello World', 'success');
    message('First Application', 'Hello World', 'error');
}

void cbDemo.say_something() {
    message('Say', :cbDemo.something, 'error');
