Re: How to LDM refreshed after submit?
I had similar problem last time: By debugging, I found some solution, that really works, but I am not sure, if it is elegant and the right wicket-way solution: 1. override onValidate method in form 2. call clearInput() method on all form components, that should refresh their model Mauro Ciancio wrote: Hi wicketers!

Re: New site developed in wicket - WWW.FITCOMPLEX.SK
Thanks to all for your response ;) About stateless ajax in jquery + wicket: JQUERY PART: --- $(#loadElementId).load( /ajax-call/most-read-articles-panel ); -- Jquery function load(url) takes markup returned from the /ajax-call/most-read-articles-panel a and loads it into the element with id loadElementId WICKET PART Wicket has to return MARKUP on specified url, here: /ajax-call/most-read-articles-panel. Processing url is simple and all about url-coding-strategies, the important part here, is that this url return markup of rendered panel - panel with most read articles in X days How to render only one panel in wicket: The simplest solution is to create web-page only for this purpose - it renders and returns only one panel markup - response will be loaded by the jquery load(..) function and replaced in HTML. Problem here is that you can load rendered markup only - dynamic CSS and JS contribution don't work, so you have to put all the needed CSS / JS into the main page. We have a little more automated wicket code - so it's possible to render any panel under specified url on a few line of codes . The point of stateless ajax is very simple - as described above ;) PS: thanks for the notice of broken tabs - i checked it, and it should be ok, because the site was running only the first day (20.4.2009), so the most read articles in the tabs are really the same in the last 2 / 7 30 days - because it was running only first day.

Re: Have a feature, want to contribute
Sounds very useful ! -especially in development model. We've spent much time debugging and searching for the one stateful component/behavior - in our large page hierarchies ! Marat Radchenko-2 wrote: Wicket pages/components can be either stateful or stateless. Wicket manages hem transparently and it is very easy to write any complex page you want. Stateful pages are much more powerful than stateless. However that comes at a cost of using page store for their state. On highload sites it is usually desired to minimize session-scope data, and move it to request-scope. That's when Wicket users approach a task of making stateful pages stateless. However stateless state (sic!) is very fragile, if you add a single stateful component to a page, it instantly becomes stateful (and you even might not notice that if your other page content can work in both modes. And here comes my lovely feature - @StatelessComponent. It is an annotation that you should put on components which you want to be stateless. It doesn't do any magic, it simply uses postComponentOnBeforeRender to assert that annotated component (and all its children) are stateless. If it doesn't, an exception is thrown, indicating what component tries to be stateful. This feature isn't large enough to be put in a separate project (just one annotation and one listener) but wee find it extremely useful on our project. I'd be happy to give it to Wicket project (or wicketstuff?) at absolutely no cost (tests included) under same license as wicket itself, if Wicket developers are interested in it. I'll file a feature request with a patch, if Wicket team finds this useful in Wicket core. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org -- View this message in context: http://www.nabble.com/Have-a-feature%2C-want-to-contribute-tp21079751p22496841.html Sent from the Wicket - User 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

Odd number of page parameters - why IllegalStateException ?
Hi all, I would like to ask, why the default URL strategy throws IllegalStateException, when there is odd number of parameters ? We have a problem with this way handling, because our users rewrite URLs manually (we cannot prevent users from doing this). Our pages are stateless and they don't use any parameters - BUT there are throwing exceptions and showing InternalErrorPage-s. It is presented like a serious problem like DB, or like service failed but there is no problem actually - only parameters, that are not used. I think, that page parameters should not result in INTERNAL ERROR, because there are many cases, where this is not relevant. There should be an alternative way - some custom handling or ignoring parameters in such a situation. What do you think about this problem ?

ImageButton - always stateful ?
Hi all,
I would like to ask, why ImageButton is stateful ?
THE CODE IN ImageButton
---
protected boolean getStatelessHint()
{
return getImageResource() == null
localizedImageResource.isStateless();
}
The method #getImageResource() return never null, so the whole method
returns always false and the
component is marked as stateful.
I use the component this way:
ImageButton submitButton = new ImageButton(submitButton, new
ResourceReference(VyhladatDomenuPanel.class, images/Search.png));
form.add(submitButton);
I know, that ImageButton uses Locale/Style to find the right image, but what
should be done, if I don't want ImageButton to be stateful ?
(problem is, that that this ImageButton binds new session, what is unwanted
behavior)
Thanx.

Presentation web with some stateful components - removing jsessionid+ all PageExpired exceptions
We are creating website. One part is standard presentation web, second part is administration site, where we take all advantages of wicket's state management. The important part here, is first presentation part. Here, all the URLs must be bookmarkable. On some special pages, we use stateful components (Gmap2). but URL of these pages are also bookmarkable. Usage of these stateful components forces http-session creation on these pages. AT THE VERY FIRST REQUEST - this makes all our bookmarkable pages not-bookmarkable, because of jsessionid added by servlet container. This is serious problem because of: - At the very first page - all links have jsessionid, so if the user bookmarks any of the links, he gets Session-Expired error. - Bots as Google bot, Yahoo remember pages with jsessionid, ... - but solution for this is very easy: - a) Use special filter, - b) or use special Response which cuts out the existing jsessionid string. No problem so far. After reading this article: http://www.nabble.com/Removing-the-jsessionid-for-SEO-td16464534i20.html#a16646137 we thought about all possible solutions and we found this way as the best for our web site. Remember please, that it is for standard presentation web, where - no jsessionid should appear - no session-expired errors are acceptable I think, this will be common use case for many others. 1. use filter/response, that cuts off the jsessionid if bot is detected in User-Agent header This solves problem for all search result URLs. 2. use our custom SessionExpiredPage, which has its own logic: a) if it detects bookmarkable page - cuts off jsessionid and redirects to the standard bookmarkable URL b) if it detects, that it is stateful page (by introspecting URL - for example contains ILinkListener and path to pagemap - then redirect to the home page. We think that it is quite acceptable solution for presentation web- see example: You have a homepage. This page has bookmarkable URL, but has some stateful components - for example Gmap2 map, which is ajax component. This stateful components forces http-session creation and makes all links with jsessionid at the very first request. When user bookmarks some URL, he saves stateful bookmark (with jsessionid). When user clicks on the bookmark later, he gets Session expired error - which causes calling of our custom Page-Expired page. This page introspects original Request, and detects, that it is standard bookmarkable page, so cuts off the jsessionid, and redirect to the normal URL, without problematic jsessionid. In case 2 - where the session actually expired on some stateful page with non-bookmarkable URL - user will be redirected to the home page. In case 3 - where presentation web works with user accounts and user must be logged on some secure pages - here, session really expired - then special UserNotLoggedException can be thrown, and handled by redirecting to the login page. What do you think about this solution (for eliminating PageExpired and jsessionid on presentation web sites) ? Are there any further pros and cons of this solution ? -- View this message in context: http://www.nabble.com/Presentation-web-with-some-stateful-components---removing-jsessionid%2B-all-PageExpired-exceptions-tp19943729p19943729.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]

PackageResource - why does'nt get Locale directly from Session ?
Hi boys, I would like to ask, why PackageResource doesn't take the Locale from the session, but in constructor ? It could be comfortable, if no Locale specified in constructor, then it could be taken directly from the session. Thanx for the answer.

Re: users, please give us your opinion: what is your take on generics with Wicket
I am one of adopters laterst release and I invested much time for upgrading all our projects to 1.4M2 . I think, that generification of Wicket has many positive impacts, but also some negative impact on simplicity and ease of use. I don't see too many advantages of fully typed components - the biggest win for me, is that I directly see, what I have or what should be in the model. I think, this is not worth the other problems. Living with generics is a little bit harder, than living with no generics. But I personally have no problem to live with it. If I should say decision, based on my experience: --- I think, that generification of Wicket involves a little bit more negative, than positive effects, so - give it away. We loose som benefits, but many other things, will be simpler.

Templating + performance question
Hi boys, I would like to ask about Templating (ass CssTemplate, ...) and performance. I think about the best solution for customizing design of our components. I see templating as a very powerful feature, but I worry about degraded performance, because of much processing when interpolating variables in every request. I saw some caching mechanism (TextTemplateCache) in sources, which could solve my problem. Could someone knowledgeable more elaborate on this problem/question please ? The Thanks very much.

Re: Using generics with some non-generic classes in Wicket
Thx Maurice, your are right. I was using Wicket 1.4M1.
I checked out latest from trunk, and it OK. ;)
So another problematic compiler warning.
For example simple - subtype of Label, which has model type of anything
Serializable.
public class ExtendedLabellt;T extends Serializablegt; extends
Labellt;Tgt{
private IStringProvider stringProvider = null;
public ExtendedLabel(String id, IModel model, IStringProvider
stringProvider) {
super(id, model);
this.stringProvider = stringProvider;
}
public ExtendedLabel(String id, String text) {
this(id, new Model(text), new BasicStringProvider());
//this(id, new Modellt;Tgt;(text), new BasicStringProvider());
//error
}
}
The problematic part, is the second constructor, which calls this. Its
second parameter - new Model(text),
which I cannot generify. If I write new Model(text), I get an error: The
constructor Model(String) is undefined.
I can't find out, what I am doing wrong.
Thx

Re: Wicket javascripts - reloading every one hour
I looked at it in detail, and it works as following: 1. You are right, when caching is too low - then browser makes request, with header If-Modified-Since. Response is 304 - that it was not modified. So the whole resource is not really downloaded, it is requested only, with short 304 response. 2. When caching time is longer, then: if resource is in caching time interval, then it is immediately taken from browser cache, without sending a request with If-Modified-Since. So the request is not performed, until caching time expires. So the overhead is not so big. Some complex applications may use many css and javascript files, and it is wasting of time for requesting these never changing files every hour again and again. Also, solution is very simple, elegant and breaks no API. And the resulting performance will be slightly better. It would be good, to have a possibility to cache these never changing static resources for a specified time, to prevent these needless requests. The only thing, that is needed to do for it, is to change WebResource#setHeaders() to take the caching time from some settings, so it is not hardcoded and can be configured by developer. What do you think about it - should I create a RFE, or it is ok ? Stefan Simik Johan Compagner wrote: But is it then really downloaded?

Re: Gzipping of pages (HTML output, not only resources)
One simple idea.
It's possible, that we use different versions of Jetty. I am using version
6.1.8.
I could'nt find either the same closing code in Gzip filter,
nor finishResponse() method,
nor such a string - This output stream has already been closed in my
jetty source code.
public void close() throws IOException {
if (closed) {
throw new IOException(This output stream has already been
closed);
}
[...]
}
I think, we must work with different versions of Jetty :)

Caching time of resources - could it be as general setting ?
Hi Wicketeers, Is it possible to take CACHING TIME for resources from some settings ? Now, this time is hardcoded in WebResource#setHeaders(...) method to 1 hour value. I know, wicket is great for creating complex dynamic applications, but I there is often no need to reload the CSS and javascript files so often. It is not problem to override this method in subclasses and use own value, but when I have done it, I can tell, that it is a too much effort of subclassing, because many important wicket components are subclasses of the WebResource class and even more components work with these subclasses which must be changed too, so there is whole dependency tree, which has to be changed, because of caching only one generic setting value. For example - if somebody want to have all javascripts and css files cached for a time of 1 week, because they are not changed and there is no need to download them more often, it is needed to create custom subclasses for: RESOURCES - custom PackageResource (which extends WebResource) - then dependent JavascriptPackageResource, - dependent CompressedPackageResource RESOURCE REFERENCES - then custom ResourceReference (which will work new custom PackageResource) - then dependent JavascriptResourceReference - dependent CompressedResourceReference ... I think, it would be very good to separate this as general setting for caching resources in some wicket settings, where it can be overriden without so much subclassing effort, which bubble up the hierarchy now.

Re: Alternative method to initialise page
John Patterson wrote: Hi, I am extending the PagingNavigatation and need to access some member variables to create my page links. Because these links are created in PagingNavigatation's constructor me subclasses newPagingNavigationLink() method is called before my subclasses member variables are initialised. I realised that this situation must occur quite often when extending any class that allows subclasses to provide or override any components. Does anyone have a nice workaround? It seems to me that creating the pages component tree in some kind of initialisation step would make classes easier to extend. Or is there already a method that should be used to do this? Thanks, John I had similar problems, when I worked with DefaultDataTable and needed to have custom PagingNavigation. For example, DefaultDataTable has no factory methods for creating custom PagingNavigation so I had to copy-paste it and change some minor parts of the class. But it was very easy and I take the default implementations as an example how to work with them.

This filter doesn't work with Wicket because wicket very often close the

if (closed) {
throw new IOException(
Cannot write to a closed output stream);
}
I asked about the same here:

Gzipping of pages (HTML output, not only resources)
Hi boys, I would like to ask, how it is possible to gzip output of wicket pages (html). I like gzipping of resources in wicket and I would like to add gzipping all pages (i.e. html output) too. Please, where in wicket can I add such a functionality or what/where should I something wrap to make it work ?

This Gzip filter will compress all the communication - HTML, resources . Images and some mime-types should be omitted. Probably, there is one drawback in IDEA 1. Wicket already caches the processed(gzipped) result, what is very useful. This functionality should be moved to the Gzip filter, which can be a lot of effort. -- View this message in context: http://www.nabble.com/Gzipping-of-pages-%28HTML-output%2C-not-only-resources%29-tp16849900p16850433.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]
DatePicker - CSS errors
Hi boys,
Firefox reports some CSS error (in Error console) when using YUI date
picker.
The problematic file is:
-
http://server/resources/org.apache.wicket.extensions.yui.YuiLib/calendar/assets/skins/sam/calendar.css
Version of the CSS file is 2.4.1. (taken from license header in source file)
There many types of error -
---
- Warning: Unknown property '_width'. Declaration dropped.
- Warning: Unknown property '_height'. Declaration dropped.
- Warning: Unknown property '_overflow'. Declaration dropped.
- Warning: Expected declaration but found '*'. Skipped to next
declaration.
When I checked the errors - the reported errors really existed.
Here are some of buggy parts, I found in CSS:
Example 1 - here is really unknown CSS property _overflow
-
.yui-calcontainer{position:relative;float:left;_overflow:hidden;}.yui-calcontainer
Example 2 - here is really * without space between the selector and its
rules
button{display:block;*display:inline-block;*overflow:visible;border:none;background-color:transparent;cursor:pointer;}
Do you find, this is a real problem, or it is probably some sort of local
problem in my application only ?

Re: onBeforeRender vs. prepareForRender
One additional question,
is it valid to change to component hierarchy in these methods ?
I tried it, but it didnt work:
SHORT EXAMPLE:
-
AjaxFallbackLink updateLink = new AjaxFallbackLink(updateLink) {
@Override
public void prepareForRender() {
super.prepareForRender();
// if some condition true - render additional attribute
if (isUpdateProcessRunning()) {
add(new
StyleAttributeAppender(text-decoration: none;));
}
}
};
and result was, that no STYLE attribute was rendered.
But when I write:
updateLink.add(new StyleAttributeAppender(text-decoration: none;));
then, the STYLE attribute is rendered.
I cannot find out, what I am doing wrong here..
Thanks a lot.

Rendering strategies question
Hello Wicketeers, I prepare report about rendering strategies (for studying community in our company) and conceptually I understand all the things, but I have one question, that I cannot answer. The default rendering strategy is RENDER_TO_BUFFER, because it solves both problems of two previous strategies: 1. no double submit problem 2. no potential problems with double attaching/detaching models But in my mind, I have problem: When some aplication has 90% of pages, that are only for viewing, and 10% of pages, that submit form, then I see, that for 90% of the view pages is the redirect not useful. For these 90% pages would be sufficient only ONE_PASS_RENDER strategy, because there is no need for redirect from my point of view. Only 10% of pages takes advantage from redirecting. Does'nt it make 90% of needless redirects ? Is it not possible tu use REDIRECT_TO_BUFFER strategy only for POST request, and for all GET request respond with ONE_PASS_RENDER ? But in WicketFilter all POST's call GET, so I think it's not possible. Is there anything I forgot to think about ?

Re: Rendering strategies question
mhmm, now I got it... In other frameworks and also in Wicket it's common to use GET request for doing some action on the server ( for example Link#onClick(...) ), so it's generally useful concept. I didn't see it from this point of view before.

Border component - naming
Hello all, I have one question about the right naming of the Border component. I think, that Border is a little confusing name, in context of swing-like border. In my opinion, border should be used as a decorator, that is transparent for component, which has it added --- it's like the new IComponentBorder interface (and MarkupComponentBorder) works. But the old component - Border behaves quite different. It's not border in swing-context, but it's like Panel. It has childs, it has own hierarchy ..The only difference I see, is that Border works with markup inheritance (with wicket:body) and Panel cannot use it. So it seems to me, that Border name is a little confusing. It's not Border - it behaves quite like normal CONTAINER, which has own childs, own hierarchy - quite like Panel. The only difference I see, is that Border uses markup inheritance through wicket:body, but panel does not. I don't know, if I understand this concept correctly... thanks in advance. -- View this message in context: http://www.nabble.com/Border-component---naming-tf4822088.html#a13795650 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: Border component - naming
thanks for your response igor, yes, you are right, i understand, that in the output html border wraps its content - so it's looks like border for nested components. What we both mean, is the same, difference is only from point of view. My point of view is, that generally (in desktop GUI like Swing - that was my swing context) borders are used for decorating some component (that's the same for wicket) but hierarchy is reversed towards wicket - for example: component.add( new LineBorder() );//like in desktop GUI Here: border knows nothing about component, that decorates In Wicket, it's reversed: border.add(component); //in Wicket So it's my point of view, that this border is container component, because other components are added to it. I know, that it results in decorating added component, but in the sense of hierarchy, other components are added to the border, so the border is container for added components. In this context I see Border quite like Panel, that can use markup inheritance through wicket:body/ I hope, you understand what I mean.. thx -- View this message in context: http://www.nabble.com/Border-component---naming-tf4822088.html#a13802790 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: TabbedPanel with image tabs
Example for AjaxTabbedPanel:
1. create new Link with image - different for selected and different for
unselected tab
MyAjaxFallbackLink.java
public class MyAjaxFallbackLink extends AjaxFallbackLink {
public MyAjaxFallbackLink(String id, boolean isSelectedTab) {
super(id);
Image image;
if (isSelectedTab){
image = new Image(image, new
ResourceReference(MyAjaxFallbackLink.class, inner-image_selected.gif));
}else{
image = new Image(image, new
ResourceReference(MyAjaxFallbackLink.class, inner-image_unselected.gif));
}
add(image);
}
public void onClick(AjaxRequestTarget target) {
//really nothing here - to override
}
}
2. override newLink() in AjaxTabbedPanel to return your link
MyAjaxTabbedPanel.java
public class MyAjaxTabbedPanel extends AjaxTabbedPanel {
public MyAjaxTabbedPanel(String id, List tabs) {
super(id, tabs);
setSelectedTab(0); //make sure, the first selected tab has
index=0.
Important for image in first selected tab!
}
protected WebMarkupContainer newLink(String linkId, final int index) {
int selectedTab = getSelectedTab();
boolean selected = (index == selectedTab);
return new MyAjaxFallbackLink(linkId, selected)
{
private static final long serialVersionUID = 1L;
public void onClick(AjaxRequestTarget target)
{
setSelectedTab(index);
if (target != null)
{
target.addComponent(MyAjaxTabbedPanel.this);
}
onAjaxUpdate(target);
}
};
}
}
3. copy html code from TabbedPanel.html and extend with image to pass
hierarchy
MyAjaxTabbedPanel.html
lt;wicket:panelgt;
lt;div wicket:id=tabs-container class=tab-rowgt;
lt;ulgt;
lt;li wicket:id=tabsgt;
lt;a href=# wicket:id=linkgt;lt;img wicket:id=image
class=left-image/gt;lt;span wicket:id=titlegt;[[tab
title]]lt;/spanlt;/agt;
lt;/ligt;
lt;/ulgt;
lt;/divgt;
lt;div wicket:id=panel class=tab-panelgt;[panel]lt;/divgt;
