Re: Clearing Session
You are right. I should not have remove the page from the constructor.
I place *getPageMap().remove(this);* after the setResponsePage in all
the pages. What is happening is
From Page 1 to Page 2 when using the back button the page expired
From Page 2 to Page 3 when using the back button the page *NOT* expiring
From Page 3 to Page 4 when using the back button the page expired
I do not know why is it so. From Page 2 to Page 3 I am sending an object
that holds the input data. So, Could it be the reason for such a behavior.
By the why in Page 2 if I call this.setEnabled(false); after
*getPageMap().remove(this);* when using the browser back button the page
is getting expired.
Any idea what is happening?!

Suad

You can't call remove from page map from Inside the page constructor!!
it isn't even IN the pagemap yet because the page is not yet constructed
and why do you think you do? why would you remove a page from the pagemap
when you still construct it and want to use it also again as a request page
(i see links on in...)
public class WelcomePage extends BasePage
{
public WelcomePage()
{
add(new Link(RegistrationFormLink){
public void onClick()
{
setResponsePage(new RegisterationPage());
*getPageMap().remove(this);*
}
});
}
}
above code should work i hope. The only thing i don't know currently if it
works correctly
is that when you call remove maybe the detach phase of the page is then
putting it back in
(Matej? do will support this still with all the new changes??)

what do you mean you added the above call to all the pages?
How do you do that?

These pages are public pages used for user registration which
takes number of steps to complete. I dont want the user to use the back
button to reset any of the previous forms. I want the page to expired in
case the user is using the back button. But the pages are not getting
expired.
Page.getPageMap().remove(Page)
I added the above call to all the pages but it only expires the first
page.

And with Page.remove() is the wrong call,
Re: Clearing Session
Removing the page is throwing the following exception: Caused by: java.lang.IllegalStateException: Cannot remove [Page class = com.individual.registration.RegisterationPage, id = 6, version = 0] from null parent! at org.apache.wicket.Component.remove(Component.java:1896) What I have is 3 pages. Page 1 has a form component, Page 2 has another form components, and Page 3 is has a label component. After submitting the form on page 1 the user will be directed to page 2 and after submitting the form the user will be directed to page 3. What I want to prevent the user from using the browser back button after submitting the form. The user should get the page has been expired. I tried getPageMap().clear(); after setResponsePage(page); in onSubmit() but nothing happen. Then I tried getPage().remove(); I got the exception mentioned earlier. Please help me. Regards, Suad Johan Compagner wrote: call remove page then the page is gone and can't be reconstructed anymore Ofcourse people can still use the back button (if the url did change from the first to the second page) and when they do that they will get a page expired.

Re: Clearing Session
PageMap.clear should work but it is a bit strange call to do. Why do you want to delete all pages? But what do you say nothing happens? What do you expect to see happening? And with Page.remove() is the wrong call, that is the default call to remove a component from its parent Maybe we should implement that that it call the pagemap and removes itself (but it is final at the moment) Page.getPageMap().remove(Page) johan On 10/26/07, Suad AlShamsi [EMAIL PROTECTED] wrote: Removing the page is throwing the following exception: Caused by: java.lang.IllegalStateException: Cannot remove [Page class = com.individual.registration.RegisterationPage, id = 6, version = 0] from null parent! at org.apache.wicket.Component.remove(Component.java:1896) What I have is 3 pages.
