Hello Adam
One posibility is to Inject ComponentSource and ComponentMessageSource, after
that you can use ComponentSource to get the page by name, and use
ComponentMessageSource to get the page Messages, something like:
private ComponentMessagesSource _componentMessageSource;
private ComponentSource _componentSource;
...
Component page = _componentSource.getPage("foo");
Messages messages = _componentMessageSource.getMessages(
page.getComponentResources().getComponentModel(),
page.getComponentResources().getLocale());
....
Maybe it would be more clean to create a specific service that you can inject
to your page.
Hope this helps.
Bye
