Re: Custom IUnauthorizedComponentInstantiationListener
hi,
could u describe the proposed solution more deeply please. Idon't
know, what more i should do with my
iauthorizationstrategy , it has only 2 boolean methods and i don't see
anything, i could improve there. Btw i use RoleAuthorizationStrategy, which is
a CompoundAuthorizationStrategy.
thanks, Juraj
if you want to hide unauthorized components you should use
iauthorizationstrategy and veto component's RENDER action

Hi, i am trying to customize the behavior, when in a page a component is

application, that is subclass of AuthenticatedWebApplication i have this
init() method:
@Override
protected void init() {
super.init();
// we customize the default behavior, when there is an component in

component) {
if (component instanceof Page) {
onUnauthorizedPage((Page) component);
} else {
component.detach();
}
}
});
}
as i can see, if the unauthorized object is a page, than i call
onUnauthorizedPage((Page) component) which redirects to login page, else i
destroy the component.
What comes out as result is that the user after accessing protected page is
redirected to login page, logs in and is authentificated but than somehow
the session is destroyed and new is created for some reason which results in
loosing the authentication and login page is displayed again. So the user
actually can't log in and always ends only in the login page.
thanks for help in advance, Juraj

Re: multiple feedback panels in same page
This does not work for me: final FormString form = new FormString(form); ComponentFeedbackMessageFilter filter = new ComponentFeedbackMessageFilter(form); FeedbackPanel feedback = new FeedbackPanel(feedback, filter); feedback.setEscapeModelStrings(false); add(feedback); None of the field level validation messages of the form go into this feedback panel - which seems like a bug. I could create a feedback panel for every field - that works fine, but this is a) too much work b) you lose the errors on a long form - you need them at the top of the form as well. So I dont see why anyone would add a feedback panel to a form if it doesnt actually catch any of the field validation. Or are you supposed to write some code on each field, catch this, and manually write to the forms feedback panel using form.info(xx)? If I use ContainerFeedbackMessageFilter then I get the feedback messages in all my feedback panels - including my global one for the separate global login form which is also pants. Any ideas how to have 2 separate feedbacks for 2 separate forms, plus a global one for anything outside this? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/multiple-feedback-panels-in-same-page-tp1886384p3217563.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: multiple feedback panels in same page
Hey i think this is documented, thats who I got to know.
Basically a 2 step process. You create a Behavior like:
/**
* This class defines a behavior so that in Feedback (on validation errors)
individual
* fields can be marked by the markup provided by the {@link
this#getErrorMarkup()}
* @author Arjun Dhar
*
* @param T
*/
public class MarkErrorFieldBehaviorT extends AbstractBehavior {
private static final long serialVersionUID = 1L;
@SuppressWarnings(unchecked)
@Override
public void onRendered(Component component) {
FormComponentT fc = (FormComponentT) component;
if (!fc.isValid()) {
Response response = component.getResponse();
response.write(getErrorMarkup());
}
}
/**
* Provide HTML markup to mark the error fieldbr/
* Example: lt;span style='color: red'gt;*lt;/spangt;
*
* @return
*/
protected String getErrorMarkup() {
return nbsp;X;
}
}
..and for your field all you have to do is .add(new
MarkErrorFieldBehaviorDouble()) -- add the behavior to it.
In my case I'm happy with X appearing. Adapt it to put the field name or
whatever text you want!

Spring Security: SecurityContext changes
Hi everyone. I am using spring security 3 with auth-roles and wicket 1.5M3, and I have a real basic implementation following the cwiki guide. It works but brokes easily: just clicking on a Home link continuosly cause the stored authentication object to get lost, in fact the SecurityContextImpl instance returned by the SecurityContextHolder (using, as of default, the ThreadLocalSecurityContextHolderStrategy) is different and of course contains a null Authentication and not the one I stored at login and that has been used for a short while. See a little log that prints the actual SecurityContext used in my implementation of AuthenticatedWebSession: 1. context: org.springframework.security.core.context.SecurityContextImpl@24c1c9c7: Authentication: org.springframework.security.authentication.UsernamePasswordAuthenticationToken@24c1c9c7: Principal: org.springframework.security.core.userdetails.User@621fc8c7: Username: daniele.dellafiore; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Granted Authorities: ADMIN; Credentials: [PROTECTED]; Authenticated: true; Details: null; Granted Authorities: ADMIN 2. (the immediate next call, seconds later) context: org.springframework.security.core.context.SecurityContextImpl@: Null authentication See, different instance. How can this happen apparently random? What should I check? I used this guide: https://cwiki.apache.org/WICKET/spring-security-and-wicket-auth-roles.html following Spring security version 3 and wicket 1.4 path The only difference is that I still use in the app init() getComponentInstantiationListeners().add(new SpringComponentInjector(this, context)); where context var is autowired and this is my web.xml (substantially identical to the cwiki one) context-param param-namecontextConfigLocation/param-name param-value classpath*:web-application.xml classpath*:security.xml /param-value /context-param listener listener-classorg.springframework.web.context.ContextLoaderListener/listener-class /listener filter filter-namefenotipi/filter-name filter-classorg.apache.wicket.protocol.http.WicketFilter/filter-class init-param param-nameapplicationFactoryClassName/param-name param-valueorg.apache.wicket.spring.SpringWebApplicationFactory/param-value /init-param /filter filter-mapping filter-namefenotipi/filter-name url-pattern/*/url-pattern /filter-mapping session-config session-timeout60/session-timeout /session-config -- Daniele Dellafiore http://danieledellafiore.net - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Custom IUnauthorizedComponentInstantiationListener
Juraj,
...
public boolean isActionAuthorized(Component component, Action action) {
return action != Component.RENDER || shouldRender(component);
}
private boolean shouldRender(Component component){
// your logic to check if the current user should see component
}
...
This is a terse and basic implementation to make the technique clear;
you should get the idea and be able to extend it to fulfil your
specific requirements..

Re: Free wicket from component hierarchy hell
I've done some work based on Igor's implementation of component queuing. It can be found here : https://github.com/koutsoub/wicket/tree/component-queuing https://github.com/koutsoub/wicket/tree/component-queuing The code is written against the 1.4.x branch, i'm also working on making it compatible with 1.5 trunk Right now the following are supported: queue method extracts hierarchy from markup files using queue and add method together nested queue methods (queue works like add) queue method working on ListItem You can have a look at ComponentQueuingTest.java with some tests with basic usage i'll raise an issue in jira with a patch during weekend Feedback and suggestions are appreciated especially more testing scenarios -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Free-wicket-from-component-hierarchy-hell-tp3027705p3218010.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: Spring Security: SecurityContext changes
Debugging deeper, it seems that in class ThreadLocalSecurityContextHolderStrategy the field ThreadLocalSecurityContext contextHolder when called for the stored SecurityContext instance with contextHolder.get(); returns null at some point so a new instance is created. This is so strange, it's the threadLocal that does not find the stored instance? How can this happen?

injected but obviously it isn't happening.
Not sure how to diagnose this problem? Any Ideas?

Re: Can't get a SortableDataProvider class to accept DI of service class
Only components are automatically injected. Google a bit

The class SortableDataProvider throws a NPE. The PersonService and the
GUIService that should be getting injected both end up being null values.
I've tried both annotations @Autowired and @SpringBean. Neither seems to
work.

Re: Can't get a SortableDataProvider class to accept DI of service class
1. Replace @Autowired with @SpringBean (do not forget to configure spring instanciation listener in WebApplication) 2. Call InjectorHolder.getInstance().inject(this) from SortableDataProvider ctor. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Can-t-get-a-SortableDataProvider-class-to-accept-DI-of-service-class-tp3218602p3218766.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
Changing/Accessing name of ListItem in ListView
Hi, when using a ListView, the name uses the following format to Render. loop name:index:field id In onSubmit(..); this is fine if you know the order of the list. However say if the primary data Structure is a hashmap then its more convenient/elegant to retrieve by Name. I can change the name of the attribute but Wicket does not recognize it when one does get(componentId). Using ListView.getList() I can access the Model, but this does not help getting the access to the individual components. Looks like the only way is to use a numberic counter and construct the Component ID's to access it one my one. Is there a way to change the component Id ..or perhaps access these by name? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Changing-Accessing-name-of-ListItem-in-ListView-tp3218777p3218777.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
