OK, I'll try to explain.
1. I have a page that has a list of links.
2. The list is taken from the database the sageDal.getPreference(..) method
that I showed.
3. This list can be configured by the user.
4. I made a Modal window that shows the user all available links (also taken
from the DB).
5. When he selects the links he wants, he presses OK.
6. Then I update the DB. The sageDal.setPreference(...) method.
As for passing Objects.
I pass the model to the LinksPanel.
LinksPanel ha a ListView that uses a different AbstarctReadOnlyModel.
So my problem is that when I set the DB with new values, I need to inform
the Model (in the original panel) somehow that the DB was changed.
