  @InjectComponent
  private Form login;

Again, we're matching the field name to the component id, and you would get an error if the component is not defined in the template.

What's the difference between the InjectPage and InjectContainer annotations?

The InjectPage annotation is used to inject some page in the application into a field of some other page. You often see it used from event handler methods:

  @InjectPage
  private ConfirmRegistration confirmRegistration;

  Object onSuccessFromRegistrationForm()
  {
    confirmRegistration.setStatus("Registration accepted");
    confirmRegistration.setValidationCode(userRegistrationData.getValidationCode());

    return confirmRegistration;
  }

This code pattern is used to configure peristent properties of a page before returning it; Tapestry will send a client redirect to the page to present
the data.

InjectContainer can be used inside a component or a mixin. In a component, it injects the immediate container of the component; this is often the top-level page object.

In a mixin, it injects the component to which the mixin is attached.

I get an exception because I have two services with the same interface, how do I handle this?
