I have a table of database entries. When there is not entry (yet), I
want to display a message (and I hide the emtpy table).
This information is created/checked during construct-time, as well as
when using a delete-link.
I see now this is seems not be the intended usage. But I see a lot of
cases where messaging is needed the first time a page ist displayed.
E.g. a blog where I use the id as a parameter to display the entry on
a separate page. I need a feedback/error-mechanism when the given id
is not found in the database.

why are you adding feedback in such a strange place?
feedback messages are meant to be added in response to an event,
like a link's onclick() or form's onsubmit().

Here is some test code. Funny though, the SimpleAttributeModifier
works.
public class MyFeedbackPanel extends FeedbackPanel {
public MyFeedbackPanel() {
super("feedback");
add(new SimpleAttributeModifier("class", "feedback") {
protected boolean isEnabled() {
return !getPage().getFeedbackMessages().isEmpty();
}
});
}
protected void onAttach() {
info("test this");
}
}
Is this a bug?

Alex
