PageExpiredException on production
hello all,
We are working with Wicket (1.3.4) on production for a couple of months. It
runs within jetty 6.1.7.
For some weeks, we are experiencing a strange PageExpiredException which
happens only on production env.
It mostly happens on 2 main Pages in which the users submit the same form in
a rolling manner (i.e. fill the form fields, submit the form, the user is
redirected to the same page with a clean form and fills the form with new
data and so on repeatedly).
It isn't a problem of session expiration because our session timeout is set
to 10 hours, this is the setting in our web.xml file:
session-config
session-timeout600/session-timeout
/session-config
We changed the logging level of Wicket to DEBUG, I'm attaching only a little
fraction from our log file,
you can see the whole exception in the file attached to this post:

Re: Going back to a previous URL?
Hi Uwe,
Thanks for your reply. Perhaps you wouldn't mind providing me with a
little bit of clarification on your technique of going back to previously
visited pages.
My application is structured like:
- abstract BasePage at the top of the Page hierarchy with a
BookmarkablePageLink to LoginPage
- AppPage extends BasePage is the main application page is mounted with
HybridURLCoding
- LoginPage extends BasePage and is mounted with HybridURLCoding
- there are other pages that extend BasePage for which the Login link is
present
- LoginPage has an AjaxForm for submitting username/password, etc..
When I'm at AppPage {1=foo} and click on the Login link, I then go to the
LoginPage with a nice URL showing in the address bar. After submitting the
login form and upon successful authentication, I want to automatically
navigate back to AppPage {1=foo} so that it is re-rendered to take into
account he user is now authenticated and consequently has more authority.
Currently what I am doing is to check the referrer in the onSubmit of the
AJAX form in LoginPage and going back to that, which brings me to the
LoginPage for some reason.
I tried to get WebPage.continueToOriginalDestination() to work in the
onSubmit and by throwing a RedirectToInterceptPage exception when clicking
on the login link, but that didn't work either.
At first glance, it seems that your solution would work the best as you have
the ability to store information in the MetaData portion of the components.
Please allow me to annotate your pseudo-code so that you can hopefully
clarify some of my questions:
Basically, Page targetPage = new LoginPage(new PageParameters());
(LoginPage doesn't have any parameters)
Page targetPage = new BookmarkablePageClass(...
create a setPageToNavigateBackTo(Page) method to store the AppPage
instance
// the add state to it, like
targetPage.setPageToNavigateBackTo(getWebPage());
store AppPage's PageParameters in the
HybridUrlCodingStrategy.PAGE_PARAMETERS_META_DATA_KEY
key so the onSubmit can redirect back
// and add params for the URL
targetPage.setMetaData(HybridUrlCodingStrategy.PAGE_PARAMETERS_META_DATA_KEY,
new PageParameters(...));
go to LoginPage
setResponsePage(targetPage);
By following the above implementation, would it not be a tad wasteful
creating LoginPage instances every time any BasePage sibling is created?
What about adding a setter in LoginPage like LoginPage.setBackPage(Class
pageClass, PageParameters pp)? I suppose this would also require the
pre-instantiation of LoginPage as well.
Are there no other mechanisms for solving this problem? Perhaps I should
look how Breadcrumbs are implemented as they have similar requirements.
Many thanks

*IF* i get this correctly, we do that by using HybridURLEncoding and
passing pageInstances around.
linking to bookmarkable urls with additional state can be done with smth
like:
Page targetPage = new BookmarkablePageClass(...

targetPage.setPageToNavigateBackTo(getWebPage());

so if not using RestartResponseAtInterceptionPage, what you want is to
a) move to a nice looking/bookmarkable url for that login page and
b) pass the reference to your current page, so that the targeting page
can do setResponsePage(myBackPage);
this can be complished using HybridUrlCodingStrategy like below.
At first glance, it seems that your solution would work the best as you have
the ability to store information in the MetaData portion of the components.
well it is more about passing data directly to the targeted page, but
STILL have a nicelooking and bookmarkable URL.
Let´s say you would not care about URLs, what you´d do is:
class A extend Page{
...
B b = new B();
b.setWhateverStateYouLike(..);
b.setMybackPage(this);
setResponsePage(b);
...
}
class B extends Page {
...
setMyBackPage(Page back){this.back=back;}
...
new Link(back){
void onClick(){
setResponsePage(back);
}
}
...
}
the 'problem' here is - for those, who care about urls - the URL you
give to B here does not have parameters.
with the mentioned
b.setMetaData(HybridUrlCodingStrategy.PAGE_PARAMETERS_META_DATA_KEY,
new PageParameters(...))
you could add parameters to the URL. That is it.
Basically, Page targetPage = new LoginPage(new PageParameters());
(LoginPage doesn't have any parameters)
Page targetPage = new BookmarkablePageClass(...
well, you don´t need parameters then ;)
By following the above implementation, would it not be a tad wasteful
creating LoginPage instances every time any BasePage sibling is created?
sure, why would you want to do that?
what about
new Link(bla){onClick(){setResponsePage(new LoginPage(...);}} ?
you´d create it when it is needed then, right?

Re: Going back to a previous URL?
Hi Uwe,
Thanks for your reply, I understand your technique now. However, what
about when we do care about URLs? For example, my LoginPageLink class is as
follows:
@NonAuthOnly
private final class LoginPageLink extends BookmarkablePageLink {
private static final long serialVersionUID = 1L;
public LoginPageLink(String id) {
super(id, LoginPage.class);
}
// @Override
// public void onClick() {
// LoginPage lp = new LoginPage();
// lp.setReferringPage(BasePage.this.getPage());
// }
}
Not really quite sure how to create an instance of LoginPage here and still
being able to use BookmarkablePageLink...
using Link produces nasty href URLs which I don't want on my public-facing
home page.
The only solution I can come up with now is to use some Link derivative and
create the static URL which will be used in the href to make it look nice
while being able to override onClick()...

Re: PageExpiredException on production
Hmm, have you supervised the process where they timeout? Or could it be
that a few users that click the back button until they reach a page
which are no longer in the pagemap, I belive 15 are the default?

Re: DropDownChoice - required, one item so preselection?
hi, the items in the DropDownChoice come from another part of the application. someone could enter the page with the DropDownChoice on it when there are three items in it but another user could delete two of them and the first user could refresh the page and ideally it would automatically select the only available option when there is functionality that looks like it should be part of the fabric of the application somewhere in a model or in a component but i'm putting it on the page somewhere that will not activate in all situations... i get the feeling that i'm doing something wrong. maybe i am not i will put the code in the constructor and will revisit this at a later date thanks for all your responses john On Thu, Aug 28, 2008 at 2:13 PM, James Carman [EMAIL PROTECTED] wrote: How are the items in the DDC changing?

WebPage error when throwing RestartResponseException in onBeforeRender
Hello everyone.
Im trying to redirect the user to another page in OnBeforeRender. I works
but I get a wierd error in the tomcat console. Here it follows:
ERROR - WebPage- You probably forgot to add a body or
header tag to your markup since no Header Container was.
But when I check on the source of the page I can see the header and body.
Here my code in onbeforerender. (The code in onbeforerender i there to
prevent the user to use the backbutton in a wizard)
protected void onBeforeRender()
{
super.onBeforeRender();
if(!mActiveStepPerformed !getForm().hasError())
{
getRequestCycle().setRedirect(true);
throw new RestartResponseException(getBackButtonRedirect());
}
mActiveStepPerformed = false;
}
The wizard panel is in a WebMarkupContainer that has
isTransparentResolver(){return true};. I saw something about this error
message and isTransparentResolver. But I didnt get it.
Can anyone exlpain?

Re: Going back to a previous URL?
I have also noticed that
HybridUrlCodingStrategy.PAGE_PARAMETERS_META_DATA_KEY will ADD my referring
page's page parameters to the URL of the target page. While it works, it's
not very elegant at all. Perhaps I'm not following your suggestion as you
intended?

Hi Uwe,
Thanks for your reply, I understand your technique now. However, what
about when we do care about URLs? For example, my LoginPageLink class is
as follows:
@NonAuthOnly
private final class LoginPageLink extends BookmarkablePageLink {
private static final long serialVersionUID = 1L;
public LoginPageLink(String id) {
super(id, LoginPage.class);
}
//@Override
//public void onClick() {
//LoginPage lp = new LoginPage();
//lp.setReferringPage(BasePage.this.getPage());
//}
}
Not really quite sure how to create an instance of LoginPage here and
still being able to use BookmarkablePageLink...
using Link produces nasty href URLs which I don't want on my public-facing
home page.
The only solution I can come up with now is to use some Link derivative
and create the static URL which will be used in the href to make it look
nice while being able to override onClick()...

navigate back to AppPage {1=foo} so that it is re-rendered to take
into
account he user is now authenticated and consequently has more
authority.
so if not using RestartResponseAtInterceptionPage, what you want is to
a) move to a nice looking/bookmarkable url for that login page and
b) pass the reference to your current page, so that the targeting page
can do setResponsePage(myBackPage);
this can be complished using HybridUrlCodingStrategy like below.
At first glance, it seems that your solution would work the best as you
have
the ability to store information in the MetaData portion of the
components.
well it is more about passing data directly to the targeted page, but
STILL have a nicelooking and bookmarkable URL.
Let´s say you would not care about URLs, what you´d do is:
class A extend Page{
...
B b = new B();
b.setWhateverStateYouLike(..);
b.setMybackPage(this);
setResponsePage(b);
...
}
class B extends Page {
...
setMyBackPage(Page back){this.back=back;}
...
new Link(back){
void onClick(){
setResponsePage(back);
}
}
...
}
the 'problem' here is - for those, who care about urls - the URL you
give to B here does not have parameters.
with the mentioned
b.setMetaData(HybridUrlCodingStrategy.PAGE_PARAMETERS_META_DATA_KEY,
new PageParameters(...))
you could add parameters to the URL. That is it.
Basically, Page targetPage = new LoginPage(new PageParameters());
(LoginPage doesn't have any parameters)
Page targetPage = new BookmarkablePageClass(...
well, you don´t need parameters then ;)
By following the above implementation, would it not be a tad wasteful
creating LoginPage instances every time any BasePage sibling is created?
sure, why would you want to do that?
what about
new Link(bla){onClick(){setResponsePage(new LoginPage(...);}} ?
you´d create it when it is needed then, right?

Authentication and authorization not working
Hi! I'm starting with Wicket. Yesterday I created a test and put basic authentication and authorization to work. After some changes, it doesn't work anymore. Basically, I have this: WebSession class extending AuthenticatedWebSession Application class overriding getHomePage(), getSignInPageClass() and getWebSessionClass(). When I try to enter on the home page, it is just going directly without go to the login page. My WebSession.authenticate method is not called, and @AuthorizeInstantiation on the home page isn't respected. What could I'm doing wrong?

Tracking logged in users / SessionStore questions
Hi guys, I'm developing a portal/forum application for my dissertation and wanted to display a panel with all currently active users. Now I found an old thread (Wicket 2.0) where Eelco posted an example SessionStore implementation to solve this specific problem, but that raised some questions. 1. Should I subclass HttpSessionStore or SecondLevelCacheSS? What is the back-button problem with HttpSessionStore? Is there another way to solve this? 2. Eelco's implementation seems to be memory only, why would I want that? What are the advantages/drawbacks? Should I implement a custom database specific session store? 3. Not that I'm hitting a million users any time soon, but what would be the best approach in terms of clustering, just out of interest?

Re: PageExpiredException on production
It is a problem to debug the process because the exception is happening only
on production and it's occurance is unpredictable.
The users don't use the back button in this senario.
They do, however, work on 2 windows of firefox simulatnously (same session)
where one window is usually the rolling input page i mentioned before, and
the other is a simple CRUD page.

Hmm, have you supervised the process where they timeout? Or could it be
that a few users that click the back button until they reach a page

We are working with Wicket (1.3.4) on production for a couple of months.

It mostly happens on 2 main Pages in which the users submit the same form
in
a rolling manner (i.e. fill the form fields, submit the form, the user is
redirected to the same page with a clean form and fills the form with new
data and so on repeatedly).
It isn't a problem of session expiration because our session timeout is
set
to 10 hours, this is the setting in our web.xml file:
session-config
session-timeout600/session-timeout

Re: java.lang.IllegalArgumentException: A child with id 'name' already exists
Well, it is hard to find out hierarchy problems. In this case you
could've added components that are siblings to the listview as childs
of the listview, instead of children of the item to the listview.
There are too many things that can go wrong in constructing the
hierarchy.
However, possibly we can improve this. Would you mind to add a JIRA
issue for this?
Thanks,

Google Chrome Wicket
I have just installed Google Chrome (v0.2.149.27). I expect this is a browser that will be supported (eventually), so it's probably a good idea to keep a list of issues in one place (here, on the Wiki or Jira) as we come across unexpected or different behaviour of our Wicket apps. To get the ball rolling, the jWeekend Add To Cart button on our http://jweekend.com/dev/BookingPage/ course booking page , that works well in all other browsers we have tried it in, is doing nothing in Google Chrome. The rest of the Ajax functionality tested so far seems to be OK. I'll send an update once I've had chance to run in development mode.

Re: Discussion on Wicket Interface Speed-Up
The problem of breaking encapsulation:
I did some work on this problem on my own a few months ago, my solution was
to use a header contrib manager, and instead of adding files with a header
contributer i add them to the manager, then get a single contributer per
page from the manger.
for example in a panel you would do
@Override
protected void onBeforeRender() {
super.onBeforeRender();
ResourceReference rr = new ResourceReference(getClass(),
test.js);
WicketApplication.get().getHcm().add(rr, getPage().getClass());
}
See how it uses getPage().getClass(), so the manager knows which class the
panel is being added into
then in the main page class
@Override
protected void onBeforeRender() {
super.onBeforeRender();
add(WicketApplication.get().getHcm().getHeaderContributor(getClass()));
}
since the manager knows all of the resources added for the page at this
point, it is easy to compress them all together and serve a single file, and
you dont have to list the files up front.
What do you think of this idea?
My code is here:
http://www.nabble.com/file/p19279269/HeaderContribManagerTest.zip
HeaderContribManagerTest.zip
It still has bugs etc in it, and doesnt really work cos ive messed up the
registerResource method, but you should be able to get the idea from it

Re: Google Chrome Wicke
Modal window seems to work fine for me, except that events are not propagated when mouse is over iframe. Tabbed panel works fine, so does editable label and clock example.

Re: Discussion on Wicket Interface Speed-Up
problem with this is that pages can have dynamic components which
dynamic header contributions.
so either you have to somehow collect all possible header
contributions from all possible component combinations - breaking
encapsulation in the process, or you have to do what you do - ending
up with many many possible and big javascript files to serve to the
user.

The problem of breaking encapsulation:
I did some work on this problem on my own a few months ago, my solution was
to use a header contrib manager, and instead of adding files with a header
contributer i add them to the manager, then get a single contributer per
page from the manger.
for example in a panel you would do
@Override
protected void onBeforeRender() {
super.onBeforeRender();
ResourceReference rr = new ResourceReference(getClass(),
test.js);
WicketApplication.get().getHcm().add(rr, getPage().getClass());
}
See how it uses getPage().getClass(), so the manager knows which class the
panel is being added into
then in the main page class
@Override
protected void onBeforeRender() {
super.onBeforeRender();
add(WicketApplication.get().getHcm().getHeaderContributor(getClass()));
}
since the manager knows all of the resources added for the page at this
point, it is easy to compress them all together and serve a single file, and
you dont have to list the files up front.
What do you think of this idea?
My code is here:
http://www.nabble.com/file/p19279269/HeaderContribManagerTest.zip
HeaderContribManagerTest.zip
It still has bugs etc in it, and doesnt really work cos ive messed up the
registerResource method, but you should be able to get the idea from it

Re: Google Chrome Wicke
I've been using 1.4-m3 and things don't work here with Google Chrome 0.2.149.27. Is there a newer version of those examples I didn't see? -- View this message in context: http://www.nabble.com/Google-Chrome---Wicket-tp19277005p19280167.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Google Chrome Wicket
That's weird since I don't get anything (examples are from 1.4-m3). For me it seems like Chrome is handling the AJAX responses differently as it's always reporting 0 characters in the response. Here's the full debug output of the modal window from Chrome when clicking on Show modal dialog with a page: INFO: Using XMLHttpRequest transport INFO: INFO: Initiating Ajax GET request on ?wicket:interface=:1:showModal1::IBehaviorListener:0:random=0.8373860055580735 INFO: Invoking pre-call handler(s)... INFO: Received ajax response (0 characters) INFO: ERROR: Error while parsing response: Could not find root ajax-response element INFO: Invoking post-call handler(s)...

Re: How do you use wicket Link to redirect you to FTP?
this was a bug, fixed.get a snapshot, build yourself from svn, or wait for the next release. -igor On Tue, Sep 2, 2008 at 4:51 PM, groffhibbitz [EMAIL PROTECTED] wrote: Hi, I'm using a wicket link component in one of my pages and when the user clicks on the link i want it to check if they are logged in, and then redirect them to this FTP url: ftp://myftpaddress.com and I tried adding a RedirectToURLException(ftp://myftpaddress.com;); to the onclick of the link, but that just tries to send me to /app/ftp://myftpaddress.com that is.. relative to the root of my web application... If I use the ExternalLink class instead of the regular Link class, I can't add any logic to the onClick method (as there is no such method in an external link).
