sure I can have reference to customerModel by making it final. But I
want to get as much garbe collected as possible at the end of request
and making the reference final wouldn't help it much :)
But considering the speed issue, maybe it is better to use
redirect_to_buffer after all ;)
one line in link handler won't kill me.

hmm because of that i didn't go for redirect_to_render..
The redirect to buffer is by far the fastest approach.
And depending on that a redirect does happen and that does the detach
and the attach again for you
doesn't seem good programming to me ;)
can't you just have a reference directly to youre customersModel ??

Okay, thank you, this works.
Nevertheless putting
getParent().getParent().getModel().detach();
to link handler doesn't seem very pretty.
Maybe like I'll just stick with Redirect to render. :)

detach youre model first.
Because a model in redirect_to_buffer isn't loaded twice because all
is done in one request.
customersModel.detach() should do the trick
or remove the deleted customer specific from that model

Hi.
For a long time I was working with render strategy set to
REDIRECT_TO_RENDER. Now I've switched to REDIRECT_TO_BUFFER and
found out, that removing items from ListViews no longer works.
I've code like
IModel customersModel = new LoadableDetachableModel() {
protected Object load() {
return CustomerDAO.getAllCustomers();
}
};
add (new ListView("customers", customersModel) {
protected void populateItem(ListItem item) {
Customer customer = (Customer) item.getModelObject();
...
item.add(new Link("delete") {
public void onClick() {
Customer customer = (Customer)
getParent().getModelObject();
CustomerDAO.delete(customer);
}
});
}
});
The problem is, that after deleting a cutomer, the list is not
updated until page refresh (the model doesn't get reloaded and list
refreshed).
What's the recommended solution to this?
Thanks.
