Sessions and announcers

Hi again, I hope I'm not in your spam lists already...

I've subclassed ILSession for my application, as I need to handle users, languages and announcements, but I couldn't find anywhere how to tell my app to use this new session class (I'm afraid they forgot to explain it at http://doc.iliadproject.org/#Using-a-custom-session-class), so I executed ILSessionManager sessionClass: MySessionClass, which I'm not sure is the right thing to do and may be the source of the rest of my problems...

The other problem is related with announcements. In this session class I have an instVar called announcer, which holds an instance of Announcer. When, in a widget called languageSelector, the user selects a language using a dropdown box, an announcement is triggered, upon which the session changes its language (it does) and all widgets listening to this announcement should update themselves, but they don't.

I've even put spies in the widgets and they seem to ignore the announcement when it happens, for instance:

MySession >> initialize

   super initialize.

   self announcer on: STALocaleChosen do: [:it | self locale: it localeString. Transcript show: it localeString]

This works, but:

MyWidget >> initialize

  super initialize.

  self session announcer on: STALocaleChosen do: [:it | self markDirty. Transcript show: 'hello, I received an announcement']

This doesn't :(

I'm not sure what's going on here... can someone shed some light?

Thank you once more!
