Hi Hannes,
Shouldn't the detaching of the ListModel be handled by the ListView
itself? Why would you detach the complete ListModel from inside a
component in the ListView? You could always send an event to the parent
of the ListItem however ...
Greetings,
Johannes

Hi!
Thanks for your feedback.
Maybe I need to elaborate my point a little bit more. It's not about Components
detaching Models but about the detaching-responsibility of dependent models.
A detach on a (child) Model, which depends on another (parent) Model normally detaches
also the parent Model. The most "prominent" example is the default
implementation of IModel.map(...).
In opposition to that, ListItemModel.detach() has a (default)
noop-implementation and I am wondering why it is not implemented as the
following:
----
@Override
public void detach()
{
listView.getModel().detach();
}
----
This is actually a problem for me, because I have a LoadableDetachableModel, which is the
"parent" Model for the ListView. This LoadableDetachableModel needs to be
detached but I don't have a reference to the LoadableDetachableModel in the Component
which is rendered inside the ListView. If detach would be implemented in the way I
proposed (and how it is implemented in IModel.map(...)), it would just work.
Thus, I suggest do implement detach as described above in ListItemModel.
Best regards,
Hannes

Subject: Re: ListItemModel is not detaching List-model
Normally it's the other way, a component detaches it's model.
The ListItemModel isn't really holding any data, it is relying on the
actual model held by listView.

Hi!
I am wondering why org.apache.wicket.markup.html.list.ListItemModel is not
detaching the ListView's model. Feels to me like a bug...or is there an
explanation?
Thanks for your help and best regards
