Re: Thanks!
Glad it worked well for you - I believe strongly that it is the best web framework available. Regarding your fear of putting the domain name in the email - if you apply some SEO tips to your site, this list would never come up ahead. I've done quite a bit of public site work where search engines gave us most of our traffic. Here are a few tips: - Make URLs that have your keywords in them (and the keywords are relevant to the page) - Use smart page titles that have search-optimized keywords in them (and again relevant to the page) - Use semantic HTML - use an H1 for the most important title on the page, H2 for subtitles, H3 for important things, EM, etc. Those three things make a phenomenal impact - in that order - URLs / titles / smart markup. -- Jeremy Thomerson http://www.wickettraining.com On Fri, Mar 27, 2009 at 5:11 PM, Kaspar Fischer wrote: > Dear list members, contributors and Wicket core developers, > > Some time ago we have deployed a website which I have migrated from > Tapestry 4.

Re: adding css and js to header
Simple:
If you're adding JS code from your Page.html file - put it in a
tag.
If you're adding it from your Page.java file - do this:
add(new AbstractBehavior() {
@Override
public void renderHead(IHeaderResponse response)
{
response.renderJavascript(javascript, id);
}
});
See the javadocs for what that ID does.

Dear list members, contributors and Wicket core developers, Some time ago we have deployed a website which I have migrated from Tapestry 4. The website is using Alfresco CMS as its data repository. The front-end and the editor back-end (the latter you cannot see without being logged in) were written in Wicket 1.4. Working with Wicket was a pleasure. Many thanks to the Wicket developers and the community for providing such a high-quality framework and for the excellent support on this forum. Cheers, Kaspar -- http://78.46.32.164/ PLEASE DO NOT POST THE NAME OF THE WEBSITE/DOMAIN OR ITS PRODUCER HERE.

Re: images in root folder
If you have an img tag, you can use a ContextImage to load an image
relative to your webapp context.
ie
HTML
Java
add(new ContextImage("myimage", "path/to/your/image");
The path will be relative to your webapp, so if your images are
deployed in the root of your webapp the path will just be "image.jpg".
cheers,
Steve

Re: Class org/apache/wicket/Component violates loader constraints
Martijn & Serkan,
I solved this problem with eclipse m2 plugin. I installed it and I
could debug my app inside eclipse with jetty.
I was looking for any duplicity or some compiler version problem, but
I was having a hard time.

Re: Caching of rendered panels
You have to be really brave to use IComponentSource :-)
It's almost never a good idea anyway. It makes sense if you have
container with big amount of small component and you can restore the
whole hierarchy from e.g. an entity Id.
but it was last time used with Wicket 1.3. There's not guarantee it will work...

Hi,
I also thought about s.th. like this because we'll have very complex
component graphs that have to be composed dynamically based on the
language of the user and ~3 other things. I thought about caching
complete component instances, but didn't come so far that I thought
about how this could be integrated into wicket - perhaps dead simple via
some
_cacheService.getReallyComplexComponentCached( "complexComponent",
userInfo )
I don't know how cheap exactly rendering of our complex component
structure will be, but if this would take more than say 10 millis we
would also try to cache already rendered markup.

Re: Caching of rendered panels
Even supposing that you don't already have some other cache engine built
into your app somewhere, couldn't you build a simple caching model class
much easier than caching rendered HTML. To cache the rendered HTML you
must:
1 - on request one, create the component, render it, cache the rendered
HTML, output it
2 - on request two, not create the component, find the rendered HTML, use a
label or something to render the html instead
Perhaps you could easily just create a caching model that wraps another
model and uses ehcache. It would be fairly simple:
See http://ehcache.sourceforge.net/samples.html
(pseudo-code)
class CachingModel extends LoadableDetachableModel {
final String cacheKey;
final IModel model;
public CachingModel(String cacheKey, IModel model) {
this.model = model;
this.cacheKey = cacheKey;
}
@Override
public T load() {
Cache cache =
CacheManager.getInstance().getCache(getClass().getSimpleName());
Element elem = cache.getElement(this.cacheKey);
if (elem == null) {
elem = new Element(this.cacheKey, this.model.getObject());
cache.put(elem);
}
return elem.getObjectValue();
}
@Override
public void onDetach() {
super.onDetach();
this.model.detach();
}
}

Re: Caching of rendered panels
In our case it's not really that the rendering itself is taking to long, it is getting the data from the model (database) so your advice is in some sense correct. Restructuring the code so that we can efficently cache the model is a lot of work and I would prefer to somehow cache the rendered html.

Class org/apache/wicket/Component violates loader constraints
People,I was working with WTP to debug my wicket app. But I decided to move
to jetty because there is no need to deploy de app, as I imagine that WTP
does. I changed from Eclipse->Project->Java-build-path the directory where
my class are compiled: src/main/webapp/WEB-INF/classes. I debug Start.java
where it says:
...
WebAppContext bb = new WebAppContext();
bb.setServer(server);
bb.setContextPath("/misDeportes");
bb.setWar("src/main/webapp");
...
But when I tried to login I got this expcetion. I really know what to do: I
mean I dont know anything about class loaders and how I reached this
situation.
Thanks in advance!

Re: Can client cache pages effectively?
Jeremy,
Thanks for your thoughtful reply - Scenario is exactly right.
I played around with page headers to make the whole page cacheable, but ran
into several problems - I have a search form, and there's an 'admin' login
that enables edit links. So it's really a stateful page, but I want to
speed up the most common state.
The bulk of the content is from an AjaxFallbackDefaultDataTable with
sortable columns. I re-sorted a column with the Ajax Debug window open to
measure it's data size - about 225000 chars. My database search takes
64ms. Overall client repaint time is about 2 sec with browser on
localhost. I haven't found the right hook to measure total wicket response
time yet, but it appears pretty quick - so that's why I thougth it made
sense to focus on client caching.
Before I give up entirely on this idea, I'm wondering if it might make sense
to make the grid a public Resource, which I'm hoping the browser would treat
like an image. I can afford a separate db query to just get my
max(lastModified), which might let me save the time to generate HTML, which
looks as though it could be my bottleneck. If this way is too hard, I'll
give up, but it sounds do-able - what do you think?
Thanks,
-- Jim.

AW: Formatting TabbedPanel with CSS
As I found out that setting the css-class works, but at the wrong place. The css-class attribute is added to the surrounding container and not to the tabbed panel. The following html code will be replaced by the tabbed panel: Reiter And this is the rendered result: Wicket constructs another container within my "tabbedPanel" container. Thats why my css doesn't take effect. Is there a way to alter the css-class of the inner container? Another thing: it is possible to disable the link of the current tab, without a custom TabbedPanel class? Thanks.

Formatting TabbedPanel with CSS
Hello,
I have a page with a TabbedPanel and want to use my own css class names for
formatting.
I tried to use a SimpleAttributeModifier to change the class attribute of the
rendered html tag, but with no effect. Then I tried to use the following code:
tabbedPanel.add(new AttributeModifier("class", new Model("tabbed_panel")));
But the rendered html looks in both cases like this:
("tab-row" should be "tabbed_panel").
Why does it not work?
And it is possible to change the css-classes of the tabs? I'd like to have once
css-class for the selected tab and a second one for not selected tabs.
Thanks in advance!

Re: Wicketizer: Create Wicket Application from DB via Hibernate
... well I thought to spice it with some Screenshots (@Marcel - you remember - do you :-)? I think about it (but it will be done at earliest in 9 days - if someone else will record, I place it on the server ). I have visited a lot of http://www.rheinjug.de/ rheinjug (Düsseldorf) meetings. The most impressive is if demo is not recorded, but live - best if the presentator quickly reacts on input from the audience. Using wicketizer.org it is possible to do it live. By the way - if someone plans a important live presentation -please inform me -then I will not do any updates in parallel. Imagine to present it on a Managers PC - and afterwards he can gamble with the application. Imho Managers have only a very little experience (mostly outdated) - and decisions are taken in many cases without understanding impacts. Although I am lucky and have boss and bossboss and bossbossboss who believe in my Knowledge, I am still restricted to work in line with Group Strategy.

AutoCompleteTextField does not get refreshed
Hi,
I use the AutoCompleteTextField to allow the users to enter tags and I have
two issues:
1)
After the user has pressed the key "enter" I want to display the entered tag
in a label
and reset the AutoCompleteTextField to allow further inputs.
So the AutoCompleteTextField should be cleared which I try by
setting a new empty String Model to AutoCompleteTextField :
final WebMarkupContainer wrapper = new WebMarkupContainer("tagWrapper");
wrapper.setOutputMarkupId(true);
form.add(wrapper);
wrapper.add(field);
selectedTags = new Label("selectedTags", new Model(""));
wrapper.add(selectedTags);
field.add(new AjaxFormSubmitBehavior(form, "onchange")
{
@Override
protected void onSubmit(AjaxRequestTarget target)
{
IModel tagModel = field.getModel();
String currentTags =
selectedTags.getDefaultModelObjectAsString();
currentTags = currentTags + " " + tagModel.getObject();
selectedTags.setDefaultModelObject(currentTags);
field.setModel(new Model(""));
//field.clearInput();
target.addComponent(wrapper);
}
});
The selectedTags label gets rerendered and displays the tags but the
AutoCompleteTextField still
shows the last users input.
How can I clear it?
2)
Ideally I want to have the AutoCompleteTextField on a form with
other input components but pressing the key "enter" causes the form to
submit
and all validartors are triggered. Can I disable the form submit for the
AutoCompleteTextField component? I know I have to change the
AjaxFormSubmitBehavior to AjaxEventBehavior and use the "onchange" event.
But even then the form gets submitted.
Does anybody has a hint what I can do?
Thanks,
Oliver

HI, this is the first strike. I first want to collect Feedback - and then decide how to proceed. My first intention was to impress Management how fast CRUD might go.

Wicketizer: Create Wicket Application from DB via Hibernate
Dear all, I have created a web site by which you can create a CRUD Application using Wicket. Create a Database (or use existing) and provide annotated hibernate POJOs and your hibernate.cfg.xml. What you will get : a complete Eclipse Project with - a menu (for all Pages) - one version using Ajax and one which only uses Ajax for Filter - per Page you will get one ListPanel (filterable and sortable and paginable) and one EditPanel (CRUDable). It will use your Hibernate Stuff. http://www.wicketizer.org http://www.wicketizer.org A detailed HowTo Page is available.

Re: Ajax refresh component
Hello,
Your problem is that you calling setOutputMarkupId(true) on the wrong
panel (you are calling it on LawView page constructor where in fact it
should be called on the component
that is added to the ajax request target, LawPanel). Also I think the
updated panel has to replace the current instance in the page hierarchy
as well as being added to the ajax request target.
Your class could benefit from using model's in a more intelligent way.
Make the LawPanel detail panel work with an IModel model. Control
the visibility of the details panel based on if there is a Law object
present.
When an ajax link is clicked just update the model value of the details
panel with the selected Law object and add the existing LawPanel into
the AJAX request target. This will allow your link to still work when
it is just a normal link (the fallback case).
For example:
Assuming the details panel lawPanel is a private variable in the main class.
Assuming in the page constuctuor the lawPanel.setOutputMarkupId(true)
method was called.
public void populateItem(final Item item) {
AjaxFallbackLink link = new
AjaxFallbackLink("linkViewLaw") {
@Override
public void onClick(AjaxRequestTarget target) {
Law law = (Law) item.getModelObject();
lawPanel.setModelObject (law);
if(target != null) {
target.addComponent(lawPanel);
}
}

Mike

Ajax components on error pages
I stumbled across a tiny problem today - i have an ajax LoginForm on each
page which either displays an error message or performs a redirect after
login. this works on all pages - except on errorpages the Ajax-debug console
throws an error (Received Ajax response with code: 404) after correctly
performing the login process on server side.
I'm not sure if a 404 should be returned there and if it wouldn't be better
if a 200 was returned if it's an ajax request. To make things short: is this
behaviour intended, should more options be offered (e.g. a flag on
ajaxcomponents where a 200 gets returned anyway) and/or should I raise a
JIRA issue for that?
regards,
Michael
PS: As a workaround I did the following in the onSubmit of my ajaxform:
if (page instanceof IErrorPage) {
final BufferedWebResponse res = (BufferedWebResponse)
RequestCycle.get().getResponse();
if (res.isAjax()) {
res.getHttpServletResponse().setStatus(HttpServletResponse.SC_OK);
}
}

AjaxFallbackDefaultDataTable and AjaxSelfUpdatingTimerBehavior
Hi All I have a question regarding how to add AjaxSelfUpdatingTimerBehaviors to some of the cells in a datatable. What is the best practice and should i use something else? Today i have a list of items which is retrieved from the database each time there is a request. The refresh rate can be set by the user in a setting page. I have made a quick solution where i was adding an AjaxSelfUpdatingTimerBehavior to the whole table. It is working perfectly fine for high refresh rates, but if the user sets the refresh rate to 1 second then the refresh gives problem. The AjaxFallbackDefaultDataTable includes checkboxes and is inside a form. I am now trying to change the logic so only the relevant cells are updated. The problem is that i cannot figure out how to do it. Because the model for each item will be called but the dataprovider is not called to retrieve the newest data from the database. Hope that someone can help or suggest a better solution. The project is open source so if you need to see code you just say the word :) Kind regards /Murat

AW: Bean Validation and Wicket
Support for JSR 303 Bean Validation in Wicket was discussed three years ago.. http://www.nabble.com/JSR-303:-Bean-Validation---Anyone-following-this--td5288109.html See comment from Eelco here: http://raibledesigns.com/rd/entry/validation_framework_consolidation#comments There seems to be no activity in this issue. I think it would be worse to spend some work for JSR 303 support in Wicket because Bean Validation will likely become a wide accepted stanard. More and more frameworks plan to support Bean Validation. JPA 2.0 is a prominent example. In my opinion validation is something that does not belong to presentation layer but to the domain layer. I find it very inelegant to declare validation for one property multiple times in different forms. A possible solution would be to declare the field once and use it in several forms, but it would be easier to declare constraints directly in the domain class and don't have to think of it when creating a form.. In my green vision you need only a custom wicket validator as a wrapper around a JSR 303 implementation like http://www.hibernate.org/412.html or http://code.google.com/p/agimatec-validation/ . Does anyone know if the integration of bean validation would be so easy? Are there any expected troubles?

DatePicker, TextField and AjaxEventBehavior
Hi,
i have problem with using datepicker in wicket. I have TextField and
DatePicker attached to it.
final TextField dateFieldfrom = new TextField("validityFrom",
new
Model(userClassification.getValidity().getValidFrom()));
dateFieldfrom.add(new DatePicker());
dateFieldfrom.add(new
DateFieldBehaviour(DateFieldBehaviour.FROM,
userClassification));
If value of textField is changed it invokes onEvent method. Its good.
Now I need to get value from textField with selected date. I have tried
getValue(), getModelObject() etc. Everything returns original value. New
value is displayed correctly but i cant get it from textField.
Any ideas?
Thx for your help.
With regards Michal

Re: Open Session in View Pattern: some basic questions
Igor, this clarified a lot. Many thanks for your very detailed reply. Kaspar On 26.03.2009, at 19:30, Igor Vaynberg wrote: there are three patterns to transaction management the default pattern is session-per-transaction. this is not convenient because after your business logic closes the transaction you can no longer use the session in the ui. there are two ways to solve this: either use session-per-request - which means on first transaction you open a session, and keep it open for the duration of the requests. transactions share the session and even after the transactions are done you still have a session. this is better because after your business logic is done you have the session you can use for ui with all the stuff from business logic already loaded. this is what the spring osiv filter does. the other way is a single transaction-per-request. this means on first access you create a session and a transaction. all other operations inside a request run within that one transaction. the difference between session-per-request and transaction-per-request is data integrity from the user's perspective. if the user sees an error page have his changes been saved to the database to some degree? with transaction-per-request you are guaranteed that if user sees an error screen none of their changes have been preserved - because whatever displayed the error screen also rolled back the transaction. with session-per-request there is no such guarantee. eg the business logic runs fine and saves the data but an error in the ui causes an error page. user sees an error - but the data is already saved - a little inconsistent. personally i prefer transaction-per-request but afaik there is nothing baked into spring that will do that so you will have to roll your own. -igor On Thu, Mar 26, 2009 at 5:31 AM, Kaspar Fischer wrote: I am learning about the OSIV pattern and have so far read the introduction at hibernate.org [1], the Spring JavaDoc for OpenSessionInViewFilter [2], the excellent MysticCoders tutorial [3] that uses Spring's OpenSessionInViewFilter, and some more. I have basic questions: 1. Is it correct that there are two variants of the pattern? In one variant there is a single transaction (and a single session) that gets committed at the end of the request, as described in [1]. If I am not mistaken, James's wicket-advanced application [5] also uses this variant. In the second variant, there is an intermediate commit. We therefore have two transactions (and one or two Hibernate sessions). Examples for this are WicketRAD and the London-Wicket PDF [4]. 2. The first variant has the disadvantage that the code handling the request cannot handle errors itself as the commit takes place at the end of the request, in a filter. Correct? As a concrete example, this means that if my code inserts an item that already exists and does not explicitly check for duplicates, the request will result in a rollback and the default error page. Where I would have preferred to see a feedback message "This item already exists". (It seems to me, however, that it is not a good practice to move error checking concerns to the database integrity layer, so the code *should* check for duplicates...) 4. Which variant(s) doe Spring's OpenSessionInViewFilter support and how does it work? I do not fully understand the documentation of the class but have the feeling it implements the second, and you can specify whether you want a single or two Hibernate sessions. I read [3]: "NOTE: This filter will by default not flush the Hibernate Session, with the flush mode set to FlushMode.NEVER. It assumes to be used in combination with service layer transactions that care for the flushing: The active transaction manager will temporarily change the flush mode to FlushMode.AUTO during a read-write transaction, with the flush mode reset toFlushMode.NEVER at the end of each transaction. If you intend to use this filter without transactions, consider changing the default flush mode (through the "flushMode" property)." Here is my understanding of this, assuming I have configured a Spring transaction manager and use transaction annotations: When a request starts, a Hibernate session is opened. When the first method with a @Transactional annotation is encountered, a transaction is started, and Hibernate's session is associated with this transaction. When the method exits, the transaction is committed but the session is left open (the OSIV behaviour). At the end of the request, the session is closed. Is this correct? Thanks for a reply and sorry for the lengthy post, Kaspar -- [1] http://www.hibernate.org/43.html [2] http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/orm/hibernate3/support/OpenSessionInViewFilter.html [3] http://www.mysticcoders.com/blog/2009/03/13/5-days-of-wicket-putting-it-all-together/ [4] http://code.google.com/p/londonwicket/downloads/det
Ajax refresh component

I would like to do the same page as the Wicket - example source code:

Re: How to secure a Wicket 1.4 application?
I'm still working on this problem myself. I'm still trying to combine wicket-auth-roles with JAAS and Glassfish. I'll let you know when I succeed. :) Regards, Linda Christian Helmbold wrote: Hello, what would be your prefered way to secure a Wicket 1.4 application? "Spring Security and Wicket-auth-roles" seems to be outdated. This project suggests to use Wicket-Security. So it is presumably not the best idea to use it. http://cwiki.apache.org/WICKET/spring-security-and-wicket-auth-roles.html Wicket-Security seems also to be not up to date and supports only Wicket 1.3. http://wicketstuff.org/confluence/display/STUFFWIKI/Wicket-Security Somewhere I've read that a version of Wicket-Security for Wicket 1.4 exists in a SVN repository. Maybe that makes Wicket-Security a candidate. But this framework looks quite complicated to me - WiComSec, WASP, Hive, SWARM sounds confusing. Is Wicket-Security limited to use JAAS permissions? http://wicketstuff.org/confluence/display/STUFFWIKI/Getting+started+with+Swarm I don't like JAAS very much ... My first impression is, that it is easier to write custom authentication and authorization, than to use Wicket-Security. How are your experiences?

YUI menu and development mode
Hi, I am trying to use YUI menu2 however when the application is deployed in development mode the menus are not working, ie no submenus, no change of color when the mouse pointer is on an item...
