Browser Page Refresh Not Really Refreshing
I have a wicket page that contains a dataview of subscriptions.
Any user that subscribes will show up on this page.
If I am already on the page and someone else create a subscription and I do
a browser refresh, like CTRL+R or F5 the user subscription does not show up.
I would have to click on the actually page link again for the new data to
show up.
Is this because I need to set my headers to not cache?

I am passing the list into the provider.

So are you passing List<Subscription> to your provider's constructor, or
are you loading a fresh list for #size() and #iterator() in each request?

I use a DataView and the data comes from the ListProvider which I created a
Sortable ListProvider.
I provided the Sortable ListProvider with a List<Subscription> which I get
through a hibernate database call.

No.
How do you iterate over your subscriptions: AbstractRepeater, ListView,
DataTable?
Where do you get the subscriptions from?

RE: Browser Page Refresh Not Really Refreshing

Thanks Paul for your guidance.
After reading your link and other links on the web to understand stateful vs
stateless, it has lead me to other questions:
Currently my application is stateful.
1. Since I am authenticating my users, does it need to be stateful because
of authentication?
I have a User Session but I don't believe I really store anything useful
(except for user authentication) or need to store previous actions that a
user may do. Seems to me like I do create stateless links, ie. creating new
pages with a constructor and only passing in PageParameters and nothing
else.
2. If I use sessions, does that mean my application cannot be stateless?
3. If my application needs to be stateful and I understand the article
properly, the reason why my refresh does not give me new data is because the
page versioning is giving me data that is at the current page version. So
how would I do it so that when there is a refresh then it would increment
the page version by one? Or should I never do that? Different way of going
about it?

You're stepping on the page cache in Wicket.
See Chapter 7 of the Wicket Guide "Page versioning and caching" at:
http://wicket.apache.org/guide/guide/chapter7.html
It really depends on what type of page you have, statefull (will rebuild
each page refresh) or not (will be cached).
~ Thank you,
Paul Bors

I feel like there isn't a need for Javascript? Should a CRTL+R or an F5
already refresh the page and reload new data in Wicket?
Is there a setting I'm forgetting to set?

Hi,
Isn't it an idea to use Javascript for this?
In JavaScript, it is also possible to refresh a page?
Example code:
