Find a component corresponding to entity
Hello *,
I'm looking for an elegant solution to determine a component for an entity.
Example:
There is a person and two sub-types of it - Manager and Sportsman.
The Manager can be listed in a listview by using a ManagerViewItem
and the Sportsman by using a SportsmanViewItem.
Currently I'm using a factory producing the appropriate viewitems. But this factory is injected by using spring.
I would like to reduce the coupling to spring within my component classes (e.g. Page).
So i'm looking for a "wicket way" to determine which component is required to list all persons.
Thanks for your ideas.

Per,
I normally do it the static factory way.. but Spring might give you the
advantage for testing (e.g in some situation just pass something that
creates an empty panels, or anything else). As Martin said, this is not
something Wicket cares about.

Hi,
Wicket doesn't prescribe any way for this.
You could use Spring, ServiceLoader, OSGi, static factory, ... Anything
that makes sense in your application.
