Re: Ajax calls loads my server
Of course, I meant javascript... thanks for the clarification. To preserve functionality, (That is, having a Select all and select none links instead of a single checkbox to select or deselect all) I will go with writing my own javascript. In addition, I have, in a different form in my application, two fields and a checkbox: field1: _ field2: _ [] checkbox I want to have a functionality that if a user types something in field2, the checkbox becomes disabled. currently I use an onChangeAjaxBehavior on the textfield, and that is AJAX, making a call to the server. I don't really want that sort of communication. Would I need to write my own javascript? is there some sort of wicket component with this sort of behavior? thanks, Benny. walnutmon wrote: While this javascript behavior doesn't qualify as Ajax, how else could you get that behavior without making an ajax component so that you can get form element objects to submit without a page refresh? Do you need to write javascript in the Wicket code? I suppose you could write javascript in the html files, but can you do things like div resizing, and other useful javascript functions using wicket? Matej Knopp-2 wrote: If it doesn't call the server than it's not Ajax... Anyway, you can accomplish what you want by writing the javascript by yourself. Or use Check, CheckGroup and CheckGroupSelector components that user client side javascript to change the state of checkboxes. -Matej On Wed, Sep 24, 2008 at 6:12 PM, Benny Weingarten [EMAIL PROTECTED] wrote: Hello.

Re: Wicket fails to set seesion and request attributes for external webpages
Thanks Igor. I did not try your solution, but instead I decided to make the External page a wicket page inside my application.

Re: Pre render action common to all pages
Some pages trigger the onBeginRequest() method in my RequestCycle around 3-4
times, others even 10 times. The number is constant for each page, i.e. for
PageA, the number of calls is always 5, and for PageB the number of calls is
always 8 (though, I haven't monitored the number of executions closely - the
number may be different between the first time a page is invoked, and
subsequent times).
The way I monitor the number of calls is a simple system.out.println call
here:
public class MyRequestCycle extends WebRequestCycle {
public MyRequestCycle(MyApp application, WebRequest request,
Response response) {
super(application, request, response);
}
@Override
protected void onBeginRequest() {
System.out.println(On begin request called!);
}
}
I wonder if the complexity of a page should have any affect on the number of
calls to RequestCycle.onBeginRequest()? if a page has many panels and those
panels in turn have even more nested panels?
thanks,
Benny.
igor.vaynberg wrote:
by numerous you mean two?
by default wicket uses something similar to redirect-after-post so
after you click a link there is a http redirect to a view-url that
will no longer execute the link. so that is two http requests/two
request cycles.

I have done that, and it is exactly what I was looking for.
However, I have noticed something that strikes me odd:
on every request to render a page in my application (every time I click a

newRequestCycle() in WebApplication is called numerous times, and
subsequently, my pre-render actions are performed many times. Is this
expected? shouldn't one page require only one RequestCycle?

Hello.
I'm writing a wicket application for facebook, but I think my problem
may
be
common to many wicket applications.
In my case, I'm using the wicket-facebook authentication strategy that
is

a
page is rendered, the AuthenticationStrategy makes sure that I have a
valid
FacebookRestClient object in my session.
In my application I need to do some other init stuff in a service
class,
and I do that in the onUnauthorizedInstantiation method. This init
information is stored in a ThreadLocal variable in my BACKEND-Service.
This
is an important point, because wicket uses many different threads for
user
requests, so I need to make sure that in the beginning of each render
request, the init information is stored on THAT REQUEST's thread.
ALL my components in all my pages and panels try to fetch information
from
the BACKEND-Service. If the BACKEND-Service hasn't been initialized
with
the
init information on the ThreadLocal variable on the same thread that
the
render request is issued on, an exception would be thrown and the page
would
fail to render.
This is all great when a user is browsing through PAGES. However, in
one
page I have a tabbedpanel. When first the user loads the page, the
authorization strategy kicks in, and the init actions are performed,
the
page renders correctly.
*** and here is my problem:
when the user clicks on the second tab in the page, the request can be
made
from a different thread (wicket controls that), but the init stuff is
not
performed because it is not a new page that needs to be rendered. This
problem also arises when I use ajax components.
I thought of putting the init stuff in the onBeforeRender() method of
each
separate component that requires the init information.
Would this be the preferred way of doing init actions for components?
Thanks,
Benny.

Re: Facebook Wicket Integration
Thanks Cao, but I don't see how this helps me. Let me further explain my situation. 1) I need to display links to the users of my facebook application. These links are DYNAMIC, so I can't put them in the markup. I have to use some sort of wicket Link component. 2) In your example, the URLs are relative URLs, as opposed to the absolute URLs that I want to display to the user. In my application, all the links (currently) are relative links, i.e. when I hover over the link when the application is running in facebook, the URL displayed at the bottom left corner of the screen is: http://my-server-doamin/page-address But I would want them to be: http://apps.facebook.com/application-name/page-address My trouble with achieving this is described at my previous post on this thread. Any further assistance on this matter would be appreciated. thanks, Benny. caoanhkiet wrote: I think you had come to http://wiki.developers.facebook.com/index.php/FBML.

I get a 4040 with the following error: The requested resource (/page2) is not available. any ideas how I can have all the links look like page2 link but work good (link page1 link)? thanks, Benny. caoanhkiet wrote: Hi, I have been following http://cwiki.apache.org/WICKET/facebook-integration.html and version tomcat 5.5.25. and ran NullPointerException. error at: client.friends_get(); SEVERE: Can't instantiate page using constructor public Login() org.apache.wicket.WicketRuntimeException: Can't instantiate page using constructor public Login() at org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:168) at org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:58) at org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:92) at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.newPage(BookmarkablePageRequestTarget.java:268) at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.getPage(BookmarkablePageRequestTarget.java:283) at org.apache.wicket.request.target.component.BookmarkablePageRequestTarget.processEvents(BookmarkablePageRequestTarget.java:210) at org.apache.wicket.request.AbstractRequestCycleProcessor.processEvents(AbstractRequestCycleProcessor.java:91) at org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1166) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1243) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1331) at org.apache.wicket.RequestCycle.request(RequestCycle.java:493) at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:363) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:194) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:174) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:151) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:874) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:665) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:528) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:81) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) -- View this message in context: http://www.nabble.com/Facebook-Wicket-Integration-tp16558748p18850389.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: Page specific authorization
Yes, I meant the RestartResponseException.
So indeed, if there is no way to access page parameters from the context of
the method isInstantiationAuthorized or isActionAuthorized (ANY INPUT ON
THIS MATTER will be appreciated :-), I will do the authorization check in
the constructor.
thanks!

Hello.
First let me congratulate this forum - I have always gotten wonderful
responses.
In my application I have a bookmarkable picture viewing page. That page
should only be viewed by users who have permission. The permissions are
stored in the DB.
When a user that doesn't have permission tries to access the page, I want
him to be redirected to the picture browsing page, with an error
message
explaining that he has no permissions to view the picture he was trying
to
access.
I have read the RoleAuthorizationStrategy and PageAuthorizationStrategy
classes and examples, and haven't found a way to make them work for me.
That
is because, in order ot determind the permission, I need the
currentUserID,
and the pictureID. The currentUserID is easy anough to obtain through the
session, but the pictureID is passed as a parameter to the constructor of
the PicturePage.
public PicturePage(long pictureID) {
... build the picture page
}
This parameter isn't available (As far as I know) to the
isPageAuthorized(Class pageClass) method of PageAuthorizationStrategy.
Thus, I have resolved to perform the authorization check at the
constructor
of the PicturePage. Is this the correct way of implementing this kind of
authorization?
Yes this is a good place to perform any check where you need more then
just the class info. The drawback is that your page is constructed for
the most part which could mean that valuable time/resources have been
wasted should you decline the request at this point.
In addition, I don't know if it is good practice to throw a
RedirectException from the isPageAuthorized() method?
Considering that isInstantiationAuthorized (which calls that method
will trigger an exception if you return false, it is allright to throw
an exception, however i hope you mean you throw a
RestartResponseException? If not you should use that.
Maurice
thanks,
Benny.

Feedback message across pages or tabs
Hello, I have searched the web for examples of what I'm trying to achieve, but could not find one. Here it is: I have a page that is used to create a user. Once the fields are filled, the user is redirected to a page that allows him to upload a picture to his newly created profile. I want the picture upload page to display a user creation success information panel, IIF the user has been redirected to the picture upload page from the user create page. Note, that the picture upload page can be accessed from various points in the web application, and in those occurrences, I don't want to display any special message at all. I have thought about adding a constructor to the picture upload page that would accept special messages. e.g: public PictureUploadPage(String specialMessage) but I think that is too ugly. In addition, I want the message to disappear after a refresh, just like the behaviour of a FeedbackPanel. The best thing would be if I could share a Feedback panel between pages, or a FeedbackMessage across pages. Any suggestions on how I can accomplish this elegantly? thanks, Benny. -- View this message in context: http://www.nabble.com/Feedback-message-across-pages-or-tabs-tp18633013p18633013.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: FeedbackPanel and page refresh (f5) after submit
I am fronting a similar problem. My users don't refresh, they go back and forward using the browser's back and forward buttons. In my wicket application, I have a FeedbackPanel in my page that displays error or success, depending on whether the form submitted successfully or not. My Form is a personal information edit form, in which a user can change information about themselves (such as name, interests, hobbies, etc`..) Lets say a user does the following in the form: 1) changes a hobby, submit the form (success). A success message is idsplayed via the FeedbackPanel 2) blanks the name field, submit the form (failure. In wicket terms, the validation failed on the TexfField Model object, and the Form's onError method was called) an error message displayed via the Feedback Panel 3) changes the name field to a valid name, then submit. (success). A success message is displayed via the FeedbackPanel At this point, if the user clicks on the browser's back button, I would expect the form to be visible with the erroneous name field, and the error message. However, the form is displayed with the value entered at (3), without any error message. User clicks back again and I would expect the form to display the new hobby field, with the success message from (1). What I see is the same page as after (3), with no feedback message. Its as if once I submit the form, the previous values of the form are not retained. I am calling setVersioned(true) on the form, and according to the docuumentation that should make the form retian previous states, but it doesn't seem to work. Suggestions? SantiagoA wrote: feedbackMessages are stored to show them once, aftewards they were deleted. Perhaps, try to store them in your own List and feed the FeedbackPanel with the List when the page is displayed again. Maybe this work, i´m not sure about that. ;-) -Santiago Thomas Lutz wrote: Hi, First of all, great framework ! I've a form with some validation added, nothing special (Required, Email check). When I submit the form I get the validation messages in the FeedbackPanel as expected, but :-), hitting f5 for a page refresh after the submit removes them (don't ask why refresh after submit... users of my webapp do stuff like this :-)). The form is not submitted, only redisplayed, but the validation messages are missing. Is there something I can do about this ?
