Re: Bean not properly injected into another bean when using Wicket stateless page
Ok, thank you Martin for detailed explanation. I understand your rationale,
to avoid future problems I have added check to our tests that makes sure
that all classes annotated with @SpringBean must have no-args constructor :)

Re: Bean not properly injected into another bean when using Wicket stateless page
Hi Martin
Two questions:
1. Which class? HomePageHandler ?
2. I have digged deeper and in fact there is a check whether to use CGLib
or Objenesis (if there is no-args constructor Objenesis is chosen) but is
it an expected behaviour? Or maybe this case could be a trigger to discuss
proper way to deal with such cases?

Bean not properly injected into another bean when using Wicket stateless page
Hello
I have a problem with wicket-spring-boot <-> wicket integration. Bean
annotated with @Serviceis not properly injected into a backing bean that is
injected into a stateless Page using @SpringBean annotation.
Generally:
@StatelessComponent
@MountPath("home-page")
public class HomePage extends WebPage {
@SpringBean
private HomePageHandler handler;
}
and
@Service
public class HomePageHandler {
private final CommandPublisher commandPublisher;
@Autowired
public HomePageHandler(CommandPublisher commandPublisher) {
this.commandPublisher = commandPublisher;
}
public void executeAction(String name) {
commandPublisher.publish(name); /// <--- NPE
(commandPublisher is null)
}
}
and:
@Service
public class CommandPublisher {
public void publish(String text) {
eventPublisher.publishEvent(text);
}
}
Wicket 7.6.0, wicket-spring-boot 1.0.6.
I have created a simple starter (
https://github.com/tdziurko/wicket-spring-bean-issue) to reproduce the
problem. Problem disappears when page is not stateless (more info in readme
in the starter).
Thank you in advance for help.

Re: Change Order (Priority) of Validator Msgs?
You should use method: final FeedbackPanel setSortingComparator(ComparatorFeedbackMessage sortingComparator) and create comparator which will sort FeedbbackMessages in proper order (in your situation probably those with feedbackMessage.component instanceof Form coming first) -- Best regards Tomasz Dziurko http://tomaszdziurko.pl

ERROR: Received Ajax response with code: 403
I have problem with page heavily using ajax and error 403 returned by ajax response. There are 4 components on the page which are shown only for specific period of time. I use AbstractAjaxTimerBehavior (duration 10ms) which is calculating current phase and then according to this phase I make some components visible and others invisible (user has limited time to answer question and after it ends he's redirected to next question). Sometimes this page stops responding to any user clicks. After running this application in debug mode I noticed that among many ajax info messages I get one error: ERROR: Received Ajax response with code: 403 Is this related to Wicket or I should talk with my server provider to check if he doesn't block ajax requests that come too often? I am using Wicket 1.3.7 Thank you in advance for any help. -- Regards Tomasz Dziurko - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Wicket timed events on page - how to?
I am writing an application for testing users and two functionalities I need to implement are: 1. show/hide some components on the page after specified time (few seconds) 2. redirect to next page after specified time I was wondering how to do this, I did some google search and seems I need to extend AbstractAjaxTimerBehavior.

Disabling 'back'/'next' web browser button usage in application
Hi. I have application which consists of questions to user provided in some order. Each question is reachable on the same address, let's say http://myApp/Question. Application engine knows which question to show from database record. Each question page has 'Previous Question' and 'Next Question' buttons which increase/decrease questionNumber in database and redirects to http://myApp/Question (which loads question looking for its number in database). My problem is: How disable 'back' and 'next' button in web browser so user can go to previous/next question only by using 'Previous Question' / 'Next Question' button? Is there a way to remove whole page from session? So user when clicks back/next will see custom communicate your session expired or you clicked 'back' or 'next' button on your web browser while doing a test'. Or maybe I could achieve such functionality in other way?

Re: Disabling 'back'/'next' web browser button usage in application
And any hint how to do this? :) I thought about two possible ways to solve my problem: 1. on clicking Next/Prev Question button remove current page from PageMap (although no idea how to do this yet ;) ) and then redirect further, so when user use back button he will see session-expired-like page 2. on clicking Next/Prev Question button invalidate Question and answers model so (not sure, but think it works this way) when user backs models will be loaded again. What do you think? Regards -- Tomasz Dziurko - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
