Re: CSRF protection and preserving page mount names
Hi,
See https://issues.apache.org/jira/browse/WICKET-4140
There is a quickstart that shows how to do it.

Hello,
I'm migrating from wicket 1.4 to 1.5 and I am looking to port the cross
site request forgery (CSRF) protection from wicket 1.4.
In 1.4, the recommended way[1] is to use CryptedUrlWebRequestCodingStrategy:
// MyWebApplication.java
@Override
protected IRequestCycleProcessor newRequestCycleProcessor()
{
return new WebRequestCycleProcessor()
{
protected IRequestCodingStrategy newRequestCodingStrategy()
{
return new CryptedUrlWebRequestCodingStrategy(new
WebRequestCodingStrategy());
}
};
}
In 1.5, this has been removed and we're asked to use
org.apache.wicket.request.mapper.CryptoMapper[2]
instead:
// MyWebApplication.java
@Override
protected void init()
{
...
mountPage(login, LoginPage.class);
...
// must be last call in init()
IRequestMapper cryptoMapper = new
CryptoMapper(getRootRequestMapper(), this);
setRootRequestMapper(cryptoMapper);
}
While this solves the CSRF problem, there is a big issue with this: there
is no longer a page mapped to login. If this were a quickstart,
http://localhost:8080/login gives a 404.
In wicket 1.4, LoginPage would be accessible via http://localhost:8080/login,
and any other page similarly mounted would give a friendly URL if you
landed on it. The only time anything would be encrypted would be during
form posts, which was perfect because that was the only time I'd need it.
In wicket 1.5, is there a way to bring this behavior back? Or am I doing
something wrong? Or is there another recommended way of protecting against
CSRF attacks?
Thanks for any help,
- Dan

RE: Freemarker+ExtJS vs Wicket questions
Plus another problem I see is if I have to use separate templates for each script tag I may end up with lots of small files so my logic will be peppered around. How is that much different from using a bunch of Wicket classes with templates instead of placing all webapp logic in a Servlet.process() method? Wicket's components natively deals with HTML templates, for other types of output via templates you need a different approach. I forgot to mention that what I actually ended up using was the Wicket combo of PackagedTextTemplate and a JavaScriptTemplate that merges in values from a Map. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: problems with AjaxFallbackLink on IE

Re: problems with AjaxFallbackLink on IE
I believe target is null when you're in fallback mode with an AjaxFallbackLink. You'll need to check for null and handle things accordingly, as though it were a normal link.

Re: problems with AjaxFallbackLink on IE
In fallback mode the entire page is being rendered, so there's no need to identify particular components that changed. Why it's falling back is perhaps an IE issue, but I think you should be prepared for null as Nicklas suggests.

Re: Event or Notice when a ListView's Model changes
But when the event is processed, I'm not in an AjaxRequest.
Anyway, I have something working, now, I am able to update a version field
(by sending an inter-component event in the onBeforeRender() of the
ListView that has it's own Form; the Event is processed by another Form at
the top of the same Panel - that's where the version field is), but I still
need an AbstractAjaxTimerBehavior - now at 3 seconds - to make the updates
visible for the user. That worries me, I would like to have an update
interval of a second, or even less, but I wonder if this is wise. My
solution now on the receiving side looks something like:
add(new AbstractAjaxTimerBehavior(Duration.seconds(3)) { // add to the Fom
@Override
public void onEvent(Component component, IEvent? event) {
if (event.getPayload() instanceof ProcessReadyNotfication) {
== Update VersionField
super.onEvent(component, event);
}
}
@Override
protected void onTimer(AjaxRequestTarget target) {
// This can take up to 3 seconds!
target.add(VersionField);
}
});
Of course, I would like something like:
@Override
public void onEvent(Component component, IEvent? event) {
if (event.getPayload() instanceof ProcessReadyNotfication) {
== Update VersionField
target.add(VersionField);
super.onEvent(component, event);
}
}
But I don't have a AjaxRequestTarget there, and obtaining one by
AjaxRequestTarget.get() causes an IllegalStateException (As far as I can
remember).

AjaxPagingNavigation not updating DataView
I have created AjaxPagingNavigation which is supposed to update a DataView The problem is that when clicking on a page number link to go to another page, the data view does not get updated. When the page is loaded for the first time there are no problems.. but when clicking on the page number link, the onBeforeRender() of the dataview is never called again, so it doesn't even call the populate method of the dataview or the iterator method of the data provider. but I have noticed that AjaxPagingNavigationLink.onClick(AjaxRequestTarget target) is being called. Any ideas? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/AjaxPagingNavigation-not-updating-DataView-tp4166358p4166358.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: ConcurrentModificationException
Thanks, Martin!
In the init(), I have:
{
getMarkupSettings().setStripWicketTags(true);
IApplicationSettings settings = getApplicationSettings();
settings.setAccessDeniedPage(AccessErr.class);
settings.setPageExpiredErrorPage(SessionErr.class);
settings.setInternalErrorPage(InternalErr.class);
// #2 starts
getRequestCycleListeners().add(new AbstractRequestCycleListener() {
public IRequestHandler onException(RequestCycle cycle, Exception e)
{
return new RedirectRequestHandler (ERROR_PAGE_URL);
}
});
// #2 ends
}
Could the #2 code block be the cause? Is this exception handler invoked before
or after the ErrorPages ?
Our authentication strategy is set up at Apache level.
This is what SessionErr class does:
getRequestCycle().replaceAllRequestHandlers (new SessionErrHandler());
And SessionErrHandler redirect to the Login Servlet. And the Login Servlet will
be routed to the WebLogin server.

Yes. You make a request to a page, Wicket searches for this page in the stores,
doesn't find it and throws PageExpiredException.
But, if the request url has the mount path then Wicket will create a new Page
instance instead. If you have authentication strategy set up then you go to the
Login page, otherwise this page will be rendered.
If you are able to reproduce the problem in a quickstart attach it to Jira so

It is called before. This is the place where your app can handle the
problem. If this method return null then Wicket falls back to the
default handling of exceptions (see DefaultExceptionMapper).
But in your case you always redirect to another page - ERROR_PAGE_URL.

RE: ConcurrentModificationException
I noticed that there are only two types of exceptions handled by this handler
so far:
1. WicketRuntimeException : Method onFormSubmitted of interface
org.apache.wicket.markup.html.form.IFormSubmitListener targeted at [SearchForm
[Component id = search_form]] on component [SearchForm [Component id =
search_form]] threw an exception
2. org.apache.wicket.request.mapper.StalePageException
Could an expired session be the underline cause for both cases?

It is called before. This is the place where your app can handle the problem.
If this method return null then Wicket falls back to the default handling of
exceptions (see DefaultExceptionMapper).
But in your case you always redirect to another page - ERROR_PAGE_URL.

Our authentication strategy is set up at Apache level.
This is what SessionErr class does:
getRequestCycle().replaceAllRequestHandlers (new
SessionErrHandler());
And SessionErrHandler redirect to the Login Servlet. And the Login Servlet
will be routed to the WebLogin server.

Convert wicket ajax posts do wicket ajax get requests
I am having issues with IE and ajax post requests.
The issue is reported here:
http://support.microsoft.com/kb/895954
As a way to address the issue, I was thinking of addressing the
application. There are several places with ajax post requests. I was
trying to see if I can convert those requests to wicket ajax gets
requests.
I am talking about radio buttons and onchange drop down boxes.
In this behavior, how would I make a change to use wicketAjaxGet and
keep the general functionality?
public abstract class AjaxFormChoiceComponentUpdatingBehavior extends
AbstractDefaultAjaxBehavior:
protected final CharSequence getEventHandler()
{
return generateCallbackScript(new
AppendingStringBuffer(wicketAjaxPost(').append(
getCallbackUrl()).append(
', wicketSerializeForm(document.getElementById(' +
getComponent().getMarkupId() +
',false;
}

WebApplication.get().getSharedResources.remove()
Hi folks,
in 1.4 I was doing (pseudo code, real code is longer):
public class MyPage extends WebPage
{
public MyPage()
{
...
DynamicImageResource image = new DynamicImageResource();
image.setImageData(_my_generated_byte_array_);
...
MyApp.get().getSharedResources().remove(/my/custom/resource.jpg);
MyApp.get().getSharedResources().add(/my/custom/resource_new,
image);
...
}
}
Not know if it's optimal but it works and resources are dynamicaly
mounted and dismounted.
In 1.5 I can't do:
MyApp.get().getSharedResources().remove(/my/custom/resource.jpg);
because remove() method in 1.5 needs ResourceReference.Key
Is there example how to work with remove() in 1.5 or how to rewrite
my code in example above?
Thanks,
JT

Re: WebApplication.get().getSharedResources.remove()
can i ask why are you dismounting?
create your resourcereference that returns your resource,use
resourcereference for mounting
and Key key =new Key(your ResourceReference)
you should also read a very nice martin-g's article on how to mount
resources in wicket 1.5
