Re: How to remove all previous pages from pagemap
Hello, Well i have to say that i spent hours yesterday trying to understand this. It was exactly as Matthias described: On clicking the back button, wicket goes to the server to fetch the page (which is o.k. - i asked browser not to cache). But instead of rendering a new bookmarkable version of the page, it rendered a wizard page that was stored in the server. Nothing helped (getSession().clear(), getPageMap.clear()). Only Matt's solution did the work (thanks Matt). This scenario of a wizard page which redirects to a message page is a very common one (and can't be defined as an ugly solution btw). Also, the need to prevent the user from going back to a wizard he just completed is also very common. Do you precious wicketiers have added/found a solution to this need in Wicket? thanks Rebecca -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-remove-all-previous-pages-from-pagemap-tp3236570p3811843.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: stateless page + click on stateless link = stateful page
Yes, otherwise the F5 would not work. It can be prevented by redirecting to
a stateless page, even if it was the last accessed one.

Re: Create a stand-alone link and get its URL
Great idea, thanks.
As I was working on passing template information as a part of the link
URL I started thinking that it would be nice if I could store this
information in session metadata and pass the metadata key as a part of
the link URL. However, I am not sure if I can pass metadata key in the
URL somehow.
Thoughts?

stateless page + click on stateless link = stateful page
Hello,
I have a stateless page with a stateless link on it. The stateless link
is used to set the session locale and nothing more. In particular, it
does not redirect to another page when clicked.
On first access to the page, the url is: localhost/servlet/login
After clicking on the stateless link, the url becomes something like:
localhost/servlet/login?8-1.ILinkListener-userPanel-en
At this point, the page is now stateful. This is caused by the
constructor PageProvider(IRequestablePage page) which has the following
code:
if (pageInstance instanceof Page)
{
((Page)pageInstance).setStatelessHint(false);
}
I don't understand why this is done. Is it because Wicket needs to make
the page stateful since the URL now contains an action listener parameter?
Is there a way to prevent the stateless page from becoming stateful?
Cheers,
Bertrand

Re: Create a stand-alone link and get its URL
add a single link to your page. expose its url as a variable to the
templating engine and append some sort of id to the url to
differentiate which template should be used. since you have to put the

Re: Create a stand-alone link and get its URL
I don't think this will work because the template could be a method
invocation, e.g.
Download
Template-evaluation approach works great for generating HTML reports,
i.e. the template evaluates to a string that contains raw HTML
".." and can be included on any page. So, here is what
a page containing HTML report looks like:
${var.studentReportWithColumnsHTML('First Name', 'Last Name')}
My code runs templating engine on the content of the editableLabel
before rendering it.
However, the new requirement is to expose the same reports for
download as CSV files and I would like to continue using the
templating mechanism and be able to support something like:
Download
Thoughts?

Thank you very much for your answer. I tried to use JProfiler. Under Windows it works fine. But in the working environment (Ubuntu 9.10, Tomcat6, Java Sun 1.6.0_24 HotSpot 64 bit mixed mode) the list with running JVMs is empty. If I use jpenable it says: No unprofiled JVMs found.

Re: why generate hybrid URL for stateless page?
Hi Kent,
Indeed the URL is hybrid but only the component info is actually used.
Since the page is stateless the page is not stored and the next
request recreates a new instance of this page class and uses the
component info (e.g. ILinkListener-form-link) to find the link and
execute its onClick method.
Maybe we can optimize this a bit by changing the page id to -1 and
don't do the lookup by page id when the link is clicked.
I.e. the generated url for components in stateless page will look
like: -1-1.ILinkListener-form-link
I'll experiment with that.
