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.
