The home page doesn't have the login logic on it, does it? Are you
persisting something into the session on login that writes the value out?
Likewise remember that the default value only gets set once, so if
you change it, it doesn't change back every time the component goes back
into the pool. So if your page sets this value it'll definitely overwrite
it.
I doubt it's either of those, but worth checking and those are the
first two horses I'd look at before I started hunting zebras.

PS What does the page spec look like where it embeds your component?
