I’m trying to show a page with a ComboBox using SQLContainer. All I’m getting is this exception:

I initialize the application with the following lines:
protected void init(VaadinRequest request) {
VaadinSession session = VaadinSession.getCurrent();
session.setConverterFactory(new MyConverterFactory());
session.setLocale(new Locale("fi", "FI"));
session.setAttribute(DB.class, new DB()); // Creating a new instance of DB will initialize the SQLContainers
SingleComponentContainer container = new Panel();
container.setWidth(100, Unit.PERCENTAGE);
setContent(container);
Navigator nav = new Navigator(this, container);
setNavigator(nav);
for(Views view : Views.values()) {
nav.addView(view.toString(), view.getViewClass());
}
nav.navigateTo(Views.MAIN.toString());
}This calls my main view’s enter() method that calls a private init() method which will initialize the components, including the ComboBox with a SQLContainer. There’s nothing special with the creation of ComboBox; I give it a caption and call setContainerDataSource() method. I’ve checked that SQLContainer gets the property id’s and row count.
It seems such a simple case. Does anybody have a clue why this isn’t working?
A few other remarks:
- View.enter is called twice after I call nav.navigateTo(). On the first call, ViewChangeEvent.getOldView() returns null and on the second call it returns MainPage.
- Filters in SQLContainers querydelegate are ignored. Is this intentional? If yes, then what is the purpose of QueryDelegate.setFilters?
