Hi,
I use a lot of "anonym-classes-models" which a want to pass to Page
instances (no need for be bookmarkable)
class HomePage() {
// some Models here
IModel<Entity> model = new LoadableDetachableModel();
//.... some Buttons-eventhandler
public onClick() {
IModel<String> m = new AbstractReadOnlyModel<String>() {
public String getObject() {
return "hello page".
}
}
setResponsePage( new HelloPage(m) );
}
//....
public void detach() {
model.detach();
}
As i discovered now, this seems not to fit conceptually.
1. using anonym model-classes <m> javac always generates a reference to
to enclosing class-instance, here <HomePage>
2. during detachment of page <HelloPage> the model <m> will ne detached
correctly (clearing transient all objects)
3. after detachment the page <HelloPage> is going to be serialized,
which the effect that the reference to the page <HomePage>
is serialized as well, without detaching thier models.
Are there any "best-practices" related to this issue?
Maybe pushing the <HomePage> on the "page-map-stack" forking
<setResponsePage>?
Thanks
Jens Zastrow
