Re: Wicket 1.5 - setResponsePage() - page still tries to render HTML before redirect
Hi, To abort the construction of the page, you throw ResetResponseException or subclasses.

I've run into the same issue- with 1.5, you can no longer short-circuit the constructor of a page, as Wicket complains if all the components haven't been added so as to match the HTML. I often use this for things like access control- if some condition isn't met, set the response to another page without rendering any components. If this is an improper use of the framework, what is the correct pattern for dealing with this? I can work around this by rendering dummy data to my components, but that's rather ugly.

Re: Redirect behaves differently between 1.4.15 and 1.4.18
Hi Gert-Jan,
I can't comment on your unit test but I have found a similar issue in
1.5.1:
WicketTester does not handle RedirectToUrlException
https://issues.apache.org/jira/browse/WICKET-4104
IMHO in a page constructor, it is preferable to use
ResetResponseException or RedirectToUrlException.
Otherwise there can be unexpected results with setResponsePage where
contents of both pages are interleaved. However I haven't tried this
in onInitialize.
I would recommend to watch the Jira issue. We could learn from the
outcome.
Regards,
Bernard

Hello all!
As I haven't received a single response yet, even though I created a

This week we upgraded to Wicket 1.4.18 from 1.4.15 and suddenly, our
unit tests started failing. It seems that it is caused by the fact that
redirect behave differently. I have attached a unit test that
demostrates this. It passes with 1.4.15, but fails with 1.4.18. To spare
you the effort of unpacking the zip, here's the test class (Note: Page1
is a simple WebPage that redirects to Page2 in it's onInitialize(), all
classes are in the zip):
package com.roboreus.geosweep.wicket;

assertTrue(Expected redirect location,
!(redirectLocation.isEmpty()));
String redirectUrl = RequestCycle.get().urlFor(Page2.class, new
PageParameters()).toString();
assertTrue(Expected redirect to ' + redirectUrl + ', but
instead got one to ' + redirectLocation + '.,
redirectLocation.contains(redirectUrl));

Do any of you know the cause of this and how to solve it?

How to set Cookie on Redirect to URL
Hi,
How do I add a cookie to a URL redirect response? I started with the
following class:
public class RedirectToUrlWithHandlerException extends
ReplaceHandlerException {
...
public RedirectToUrlWithHandlerException(final String redirectUrl,
final int statusCode, final IRequestHandler handler) {
super(new RedirectRequestHandler(redirectUrl, statusCode){
@Override
public void detach(IRequestCycle requestCycle) {
super.detach(requestCycle);
handler.detach(requestCycle);
}
@Override
public void respond(IRequestCycle requestCycle) {
super.respond(requestCycle);
handler.respond(requestCycle);
}
}, true);
}
}
and in the page:
throw new RedirectToUrlWithHandlerException(targetUrl, new
IRequestHandler(){
@Override
public void respond(IRequestCycle requestCycle) {
// Set cookie
cookieUtils.save(name, value);
}
@Override
public void detach(IRequestCycle requestCycle) { }
});
with cookieUtils:
instance.cookieUtils = new CookieUtils(cookieDefaults){
@Override
protected void initializeCookie(Cookie cookie) {
super.initializeCookie(cookie);
cookie.setPath(/);
}
};
Still no cookie in the response.
I know this is a tricky issue where older browsers don't always
cooperate, but the page being redirected to can't set the cookie
because the cookie is used to transfer information to it.
Many thanks,
Bernard

IDE / Server Support
Hi, How do you get fast deployment in development with large Wicket EJB applications? Wicket pages are ordinary class files that do not always seem to have special redeployment support like JSP files or HTML files. I have an EJB 3.1 app deployed on GlassFish 3.1. Web pages in the web directory deploy automatically in milliseconds, but whenever I save a Java class file, deploy on save deploys the whole application. This is not a big deal with hello world apps, but it hurts badly otherwise. As an example I tried the Wicket example application with hundreds of class files which takes more than half a minute to deploy on fast computers, and during that time, the IDE freezes. I thought that a decent servlet container should be able to detect single class file changes and hot-deploy them individually. But I might be wrong. The NetBeans folks think otherwise and refer me to the GlassFish server docs. I don't care so much about their view because what matters to me is the fact that - say a PHP developer - just saves his files and hits the reload button, and that is what I try to get, too. Otherwise I feel I am fighting an uphill battle. Any thoughts are appreciated.

Re: Handling first AJAX request when cookies are disabled

Is this being done by the servlet container (I'm using Jetty), or is it handled elsewhere in the stack?

Re: How to invalidate session after panel replacement?
Thanks Ernesto.
It is doable without JavaScript:
WebRequestCycle requestCycle = (WebRequestCycle) RequestCycle.get();
WebRequest webRequest = (WebRequest) requestCycle.getRequest();
HttpServletRequest httpServletRequest =
webRequest.getHttpServletRequest();
httpServletRequest.getSession().setMaxInactiveInterval(5);
It is not perfect, and I thought that Wicket, depending so heavily on
the session, would provide a means to destroy it after use.

Bernard,
There was someone asking something similar a few day ago... One idea
that might work is
-Put an ajax behavior on your page (AbstractDefaultAjaxBehavior) and
use it to generate a callback url.
-Use a non wicket AJAX (e.g. jquery AJAX) to call this behavior.
-Make your panel call back this behavior when it is loaded. E.g make
it implement IHeaderContributor and on
public void renderHead(IHeaderResponse response)
{
response.renderOnDomReadyJavascript(Put your AJAX call here!);
}
I think you can't use wicket AJAX because it will redirect you if you
invalidate the session.
-On the AbstractDefaultAjaxBehavior.respond(AjaxRequestTarget target)
invalidate your session.

Re: [1.5] new wicket URL-related questions
Hi, A2: http://blog.armstrongconsulting.com/?p=14 A4: I will look at this in 1.5 myself at some stage as well, so please keep in touch. Meanwhile, have you seen http://day-to-day-stuff.blogspot.com/2008/10/wicket-extreme-consistent-urls.html I have a special use case for this where I don't want to create browser history entries of different versions of a stateful page (back button problem solution).

Re: How to get submitting component in onError()?
Hi James, Thank you very much for your reply. It didn't work because the form was submitted with input type=image, and I did not add an ImageButton for it. Things would be a little easier if there was an overridable onClick() method for submitting components not this Where was I type of back to front logic. When using an ImageButton, one is forced to store the image as resource in the Java package structure which is another complication because web designers want to control such images in the web directory.

jsessionid in URLs of non-versioned Pages
Hi, I use panel replacement on setVersioned(false) pages in combination with HybridUrlCodingStrategy and the default IRequestCycleSettings.REDIRECT_TO_BUFFER so that users stay on the same page and cannot see previos versions when pressing the back button. That is because all pages have the same URL. With the first request the servlet container doesn't know you have cookie support. So it will append the jsessionid to the URL. After that with the second request it sees the cookie coming in and then it doesn't append the jsessionid anymore. This is then creating two pages in browser history one with jsessionid and one without it which is causing me a headache: If on subsequent requests, the user presses the back button and re-submits, then the submit hits the only last version of the non-versioned page which lacks the (replaced) form to submit to and the page crashes. Any ideas would be highly appreciated. Regards, Bernard - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: How to Update contents of a child component?
Hi, Have you checked that rendered values in your components are model-driven? If so then I think it should work. I sometimes set values in the constructor with brute force when I do not expect any changes. This is not what you want in this case. I found it most helpful to exclusively use LoadableDetachableModel, remove the Serializable interface from my model objects and let SerializableChecker sort out some model problems for me. I went so far as to use a LDM in my WebSession. After some time I had sufficient practice with models that things started to become really easy.

with:
String requestURI = (String)

if (requestURI == null) {
requestURI = request.getRequestURI();
}
String path = Strings.stripJSessionId(requestURI);
I tried to debug the code and the filter is called, but then nothing is
displayed on the browser.. just a blank page..
If I call page directly(not the jsp) , it renders correctly..

Re: ResourceStreamLocator and mvn resource:resource copying resources in the right directory
Hi Erik,
I know the problem. It is a JavaScript problem, where the browser has
to construct an absolute URL from the relative URL that is in the HTML
fragment. The question is relative to what context this URL has to be
constructed in the browser - relative to the source of the fragment,
to some iframe or to the source of the page it is inserted into.
I am not arguing with you that you have found a good solution to the
problem.
But if you wanted to solve the problem at the root of it, you would
code the relative URLs at the server, and make them absolute at the
client side. The conversion is quite trivial. I did this for a
JavaScript based e-commerce app some time ago. This will always work
because the browser cannot reqest relative URLs anyway.
Regarding Wicket's inability to do this out of the box, I am once
again disappointed. This is so basic it blows my mind. While Wicket is
very flexible in many areas, in some areas it forces special use cases
as best practice on site develpers who then don't have any choices.
RelativePathPrefixHandler just breaks things by making a stupid
assumption about paths. I wish I could replace it dynamically.
If I start making alternative suggesions, then I am hearing catchy
words like best practice community consensus , begginner and we
like to do it this way. That never convinces anyone because there is
no such thing as a community consensus, and especially not one that
agrees on a special use case.
I would say that putting HTML pages alongside Java source files is a
special use case for component deployment. It is ridiculous to call
this Wicket best practice for site development. Once you explore
benefits eg better separation of concerns of the more general cases,
you run into trouble only because the original designers did not
consider them enough. A framework might originate from special use
cases but it should at some stage address general cases with higher
priority not as never ending afterthoughts. These things should be
pluggable.

Bernard

Hi Bernard,
We are using absolute URLs in one application (http://tipspot.com) that
does not use the wicket ajax library, only javascript (based on jquery)
written by the frontend developer. One of the things we do there is
filling popups through ajax requests. As most of that information is
completely stateless, we use a wicket page to produce the html
fragments. The URL depth and path of the original page (containing the
popup), and the page that is pasted into the popup, almost never
matches. This is a problem for linking to other pages. I found it easy
to make this problem go away by making all URLs absolute.
I did not look at RelativePathPrefixHandler as I was unaware of its
existence. I am also not certain that any relative schema would be able
to solve the problem cleanly/easily. Secondly having absolute paths is a
non-issue for this application.

Re: ResourceStreamLocator and mvn resource:resource copying resources in the right directory
Hi Fernando,
obviously quite a few including yourself are separating markup from
Java packages to make it accessable to HTML developers.
How do you cope with the fact that Wicket markup, when rendered in any
folder without flattening the package structure, gets broken images?
That is what I am trying to address with
Cannot substitute RelativePathPrefixHandler
https://issues.apache.org/jira/browse/WICKET-2881
The three lines of Java code in RelativePathPrefixHandler are solving
this problem.
int lastIndex = attrValue.lastIndexOf(../);
if (lastIndex = 0){
attrValue = attrValue.substring(lastIndex + 3);
}
Regards,
Bernard

Your resources will be protected by web-inf and the configuration is the

Hi,
You could have the files in a sibling directory in the web directory

Allows web developers to freely edit and view files in context with

someone suggest how to get the three lines of code into Wicket that

Re: Can I develop without recompiling/restarting after every change?
Hi Yes, I understand that. But you have to put the markup for each component somewhere. If it's not on the classpath, then you will not be able to package that component into a JAR for re-use. As I wrote, both methods co-exist, and you can put markup on the classpath and package it as jar while other markup is separate from the classpath. How otherwise would I be able to use Wicket components with my scheme? Please accept the good news that your but is not justified. No, we disagree because I think that doing nothing, i.e. keeping your component markup on the classpath, *is* the best practice, that is, the majority opinion on what makes the most sense for most people. Quoting majority opinion and community consensus is a very weak contribution to innovation, a sign that the speaker is running out of genuine ideas. In such context I would typically say that my views represent the other 100% of such perceived majority/consensus, just to make it absolutely clear what kind of Orwellian bsht this is. Page developers, especially those who work with markup, and that is the majority that Wicket is targeting (not component developers) need the markup in the context of their resolvable image, script and other resource files which is in the web directory. Otherwise they cannot view the markup in the browser. They don't care where these files are at runtime as long as they are not broken at design time which they currently are. You never seem to comment on this critical point. If you feel that the default approach isn't the best practice, then you are saying that the Wicket designers made a mistake by making this the default. I disagree strongly with that sentiment. You accept broken markup at design time and I don't accept it because I have solved the problem. I would not go as far as to say they made THAT mistake. As you know, they gave us the option. But the non-default option is broken because of the missing three lines of Java code, and whenever people try it, they become part of your perceived community consensus due to frustration. Like prisoners. I think perhaps we mean different things by deploy on save. When I say deploy I mean it in the J2EE sense, where the container re-loads my WAR package. In my case, this re-loads my Spring context and a few dozen JPA entity beans, which takes up to 15 seconds on my relatively modern laptop. There is no way rearranging my markup (or running it on a fully certified J2EE server) would turn this into milliseconds. True. deploy on save is not invented here. It is a term used in IDEs. The IDE decides what deployment method to use depending on file location etc.. That is one of two reasons why I would recommend to not store page markup in Java package directories. Look, the only reason I took up this (now too long) thread is your use of the words best practice, which implies a broadly held consensus. Now that you've included as I see it I'm happy to let it drop. Wrong. Best practice does not imply broadly held consensus at all. I am not using this as a buzzword as you are. If I invent a better mouse trap today that is more effective at delivering the outcome than any other technique, while the better mouse trap is not even available or known to everyone, then using it becomes best practice overnight.

Re: Can I develop without recompiling/restarting after every change?
Hi, I don't agree that it's the best approach in all environments, and I think your advice negates one of the best features of Wicket, namely the ability to package complete Wicket components (including their markup and other resources) into JAR files for convenient re-use across applications. Wrong. Let me repeat what I wrote in my previos article: This would not break the ability of packaging markup of some components in the classpath because Wicket can handle that at the same time. If you study the effects of adding resource paths in Wicket then you will find that both methods will co-exist, not negate each other as you write. There are environments such as yours and other trivial environments where nothing needs to be done at all. That does not mean that doing nothing is best practice. Best practice is something else. A best approach in an individual case may be different from best practice, and that is why you disagree. I think perhaps you're missing the point here. In my development environment (Eclipse+Tomcat) I *don't* re-deploy on save. That would be far too slow. But any markup changes I make (and a good portion of the Java changes, too) are usually picked up by the time I Alt-Tab to my browser and refresh the page. With my proposed method, your cycle would not be affected at all. You would still have all your benefits. My method is inclusive and general wheteher you chose to deploy on save or not. Deploy on save would take only milliseconds (with my proposed path structure applied) and the session would be preserved if you were using GlassFish 3.0 and NetBeans, leading to a performance gain. You may not need this functionality, but your setup seems to be slower than what is achievable. I think that was Martijn's point: if you're doing re-deploy on save in your development environment (as the OP implied he was) then you're doing it wrong. No amount of moving markup around is goint to change this. I am sorry your statement is wrong. You are assuming that I am using Tomcat. For fully certified J2EE servers, and I wrote that my general approach includes these, IDE instrumentation is not necessarily the same as for Tomcat. Yes I am moving markup around. And that (with an additional 3 lines of framwork code) leads to a re-definition of best practice for Wicket page development as I see it because of two gains: - Markup re-factoring within the scope of the web directory becomes possible because links are no longer broken - Application server IDE instrumentation can make better deployment choices for deploy on save optimisation I am not claiming that you will personally benefit from this. You seem to be happy enough with your setup. Regards, Bernard - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Can I develop without recompiling/restarting after every change?
Hi, My suggestions were meant to be general, and with best I actually meant in all environments including certified J2EE servers. Any number of environments (Igor suggested Jetty) may work with or without these suggestions. That is because deployment environments may or may not make decisions on which way to deploy different file types, or depending on directories they are loaded from. Files in the web directory are quite obviously candidates for the fastest deployment method. If the environment thinks that HTML files need to be deployed in the same way as Java files, which is quite likely if they are stored in Java packages, then deploy-on-save setups may slow down the development process of complex applications due to heavy CPU use. Therefore, fetching markup from the web directory not from the classpath is clearly superior under some of these conditions. This would not break the ability of packaging markup of some components in the classpath because Wicket can handle that at the same time. There is no need to squeeze my comments into the frame of your community consensus. I am perfectly happy if my comments are correct only for the other 100% of the community that I am targeting. OT: If Wicket adds the trivial feature of resolving HTML resource links differently then finally there will be separation of concerns. It will be possible to resolve links to resources e.g. css files, images when loading HTML files from the local file system in the package structure in the web directory. And finally one would be able to use markup refactoring that is available in today's tools. This is cheap stuff and I am perplexed why it is not happening. Three lines of code - better practice.

The way your original post is phrased makes it sound like a best practice, and it implies the Wicket default to fetch markup from the classpath is inferior.

I don't want to - have the wicket filter serve the resources - have the resources stored under WEB-INF/classes So I tried in init() getResourceSettings(addResourceFolder(wicket)); but that is where Wicket support ends because I still have to use link rel='stylesheet' type='text/css' href='style.css'/ which works at runtime but not for any IDE for offline viewing and refactoring.

HTML editing, HTML templates, HTML refactoring
Hi, IDE technology now offers HTML refactoring support even including css style selectors. Dreamweaver supports HTML remplates. In principle, Wicket could support these technologies due to its clean HTML approach. However, I have not been able to get any of this to work, because Wicket ignores its own Java package structure. I am prepared to do whatever is necessary, e.g. storing HTML page files outside Java packages. So far, if I do that, then I need to duplicate the Java package structure in the web directory. With that, all resource links e.g. images, css have to be ../../../... for the web developers, but for Wicket they have to be . So currently, refactoring does not work, and I have to copy every page into the web root for viewing. How can I provide the best editing experience for HTML developers so that all links work, and so that Dreamweaver templates and IDE refactoring are not broken?

Re: HTML editing, HTML templates, HTML refactoring
Jeremy, I am not asking for full previewbly in the sense that you are describing. Obviously this is not possible in dynamic scenarios. However, Dreamweaver provides templates where each panel can be previewed in the context of a page so it is Dreamweaver that provides full previewability. I have seen this documented at http://www.2rue.de/hacking/wicket/leveraging-wicket-templates-for-offline-viewing-with-dreamweaver/ However, whether dynamic content can be previewed or not, it can always be filled with something that gets replaced at runtime anyway. In any case, I want to get the HTML resource paths right, so how do I do that? I haven't seen a solution for that yet.

How to get stable DOM IDs without hacks?
Hi,
Wicket has its own mind - it changes IDs in HTML forms so JavaScript
breaks.
Example:
Source:
input type=button wicket:id=addButton id=addButton
value=Add/
Generated:
input type=button id=addButtona value=Add name=addButton/
Please note that Wicket renames the id from addButton to
addButtona while it does not change the name attribute value.
So we would have to create a Button subclass and:
@Override
public String getMarkupId(){
// As an example, use the wicket:id value ...
return getId();
}
and in HTML, we have to write a warning as a reminder of this hack:
!-- Wicket overrides id from wicket:id value --
This is a maintenance problem and a performance problem because the
additinal classes cost memory and CPU.
Any ideas?

Like Pierre said, component.setMarkupId(component.getId()) will work, but it
was discussed just a couple of weeks ago why that's a bad approach. The
thread isn't appearing on nabble though, not sure why that is. Anyway, a
safer approach (to prevent duplicate ID issues) is to generate your javascript
calls at the server using the markup ID as a parameter. It sounds like you
have a function like
function func() {
var elem = document.getElementById(someId);
// do stuff to the element
}
so just modify to
function func(id) {
var elem = document.getElementById(id);
// do stuff to the element
}
and output a call to that function using something like a
StringHeaderContributor or implement IHeaderContributor if you need to call at
page load or use AjaxRequestTarget if in an ajax request.

Hello,

Hi,
Wicket has its own mind - it changes IDs in HTML forms so JavaScript

input type=button wicket:id=addButton id=addButton

Re: Caching components
But why in repeating views are the components duplicated for each row? Wicket should re-use the components - one instance for each row could do all the rendering.

Re: Caching components
Igor, I don't understand the optimal use of the different repeaters list views in different scenarios well enough yet, so I would be greateful if someone could provide a link for more documentation. As far as I understand, though, refreshingview.setreuseitemstrategy() is about re-using items - it is all about models. I am thinking about re-using the rendering component for ALL items in the collection. That would not require any strategy. And I would want this to work with database driven collections, so far I have used DataProvider with LDMs. What needs to be done to get re-used components in this scenario?

Re: jquery and wicket
I can't tell you all the rules for compatibility and interoperability with Wicket's own js library. I think you will find answers on that with web searches. But I can tell you that I use jQuery without problems. I use jsTree, jqModal and other components. I exchange data via Wicket HiddenField. Please note that Wicket generates the names of the hidden fields, so you might either want to override the names in Java or use ids to address the hidden fields in your js.

you put the ball back into their court. I did this more than once but

Re: jWicket release 0.5.0
Ernesto,
Possibly not enough. I would create a testcase as a web page with no
reference to Wicket as a start.
It is good to avoid any technical distraction because any distraction
causes friction and loss of energy.
You can of course mention that you are a Wicket developer, and give
some context to support your case, even mentioning that this is being
discussed in this group.
If you are 100% sure that your scenario is the same as in 4996, then I
would attach the testcase to that ticket. Otherwise I would open a new
one, without any reference to the old one.
If you are sure about the previous code snippet being not much
different from your attached testcase, then why not mention it,
pointing out that you are just trying to be helpful. You can then ask
what else they need to avoid any further delays.
In case it is the same issue then I would subscribe to the jQuery dev
mailing list (not user mailing list) and notify them that you are
trying to re-start the issue ...
Technically, the issue surprises me from this perspective:
jQuery is fault tolerant in a way that if you run a query that returns
an empty jQuery object and call methods on that empty object, then the
query does not fail. In this case however it fails. I would try to
emphasize this point if possible, concluding that this is in conflict
with jQuery's own apparent design principles.

Bernard

Wicket Examples on NetBeans
Hi, How can I run the wicket examples that are included in the distribution in the NetBeans IDE? I have tried to open the Maven project but I get errors [0] 'dependencies.dependency.version' is missing for org.apache.wicket:wicket It would be nice to have a quick and easy way to get these running in NetBeans so that I can use the Wicket Examples as an easy reference and starting point for the NetBeans developers (testcases for performance issues etc.). Ideally, I would just want to ask them to open the Maven project, specify a server i.e. GlassFish V3 and run the project.

Re: Large number components and redering time
In case of repeated buttons I think I would use a combination of a TableCellEditor and a TableCellRenderer with a button behind them, still only single instances serving many rows. There would only be a single event listener that would check selected row index. Would it make sense to have that in Wicket in the future? Might save a lot of memory. If on the other hand this button would be only needed on specific cells, not the pure repeater scenario, then of course one would use simple button instances per cell as there would not be a significant memory saving.

How to hide / show additional descriptive Row below empty DataView?
Hi all,
How is it possible to dynamically show and hide an additional dummy
row No items to show below a DataView?
I tried this with code similar to code below but it does not work even
though isVisible() is called. I have a small testcase ready to go.
It's quite basic so I must be missing something obvious.
Many thanks
Bernard
In a DataView, with an AjaxFallbackLink delete action, in onClick I do
something like
item.setVisible(false);
target.addComponent(item);
target.addComponent(emptyRow);
with emptyRow as follows:
final WebMarkupContainer emptyRow = new
WebMarkupContainer(emptyRow){
@Override
public boolean isVisible(){
return rowProvider.size() == 0;
}
};
emptyRow.setOutputMarkupId(true);
add(emptyRow);
In HTML:
tr wicket:id=dataRow
td wicket:id=IdID/td
tda wicket:id=deleteDelete/a/td
/tr
tr wicket:id=emptyRow
td colspan=2No Items to show/td
/tr

Re: Help with Wicket Adoption Numbers
Hi Lester, If you think your boss will not accept the benefits, then why not show him the risk of sticking with a technology (Struts) that is in decline? Then suddenly he shoulders the burden of making the desision of taking ownership of a sinking ship.

I REALLY don't want to go there, and am even considering not taking part in this project due to the high risk involved, only 9 months to introduce huge changes to a system that has lots of legacy problems (took about 3 years to build). I think a lot of those years were spent wrestling with the monster that is EJB 1.1. The only way I thought the project can even be on time is to scrap the entire presentation layer (aka Struts) and redo it in Wicket with 1 dedicated developer while the rest of the team work on killing the beast that is EJB 1.1 by refactoring the biz code. Sigh, my choices are stark. It's either to keep the job and plough ahead and probably fail spectacularly 9 months later or go hungry and explain to my wife why we need to spend less on the kid.. It's easy to blame the tech committee but they did help me find wicket by rejecting my initial proposal to build the new system on a (JQuery+JSON+REST) framework, which can be very productive as well, if not as clean as Wicket. Sorry for rambling so much. Is there any way I can demolish the silly low adoption rate argument (omg I still don't believe it can be so lame)?

Re: Tag Oriented Development
JSF == Standard? My question is: What should become a standard? When I think about standards, then things that come to mind are: - SQL - ODBC - Java - JDBC - EJB - JPA but not JSF. And not Spring. And not ... - you name it. For some reason, possibly due to the fast evolving nature of the web, web frameworks are higher up in the food chain, and I don't think that we are ready yet to standardize on that level. People may say JSF is a standard, so what? The fact that there are so many others seems to prove my point.

Re: @RequireHttps - forms misbehaving
Hi VGJ, If, as you say you can reproduce this in your storefront app no matter where you use it then you may want to reduce this to a testcase and create a jira issue from it. You are already writing that you can reproduce it and consequently it would be only a matter of removing all distracting detail from your storefront until further simplification is no longer possible. I can't see how otherwise anyone could help you with your issue. In any case, glitches like you mention should not happen whether the problem is in the Wicket framework domain or in the application domain. If it is in the application domain, as it would usually be the case because Wicket is mature, then there would still be a benefit of publishing the issue e.g. in a Wiki article so that others would not make the same mistake.

Global FeedbackPanel and ComponentFeedbackPanel on the same Page ?
Hi,
It appears that Wicket already has everything I need:
- A global FeedbackPanel for any messages not necessarily associated
with components (a call error(...) displays the message on it)
- An individual ComponentFeedbackPanel for messages belonging to and
displayed in context of components.
My question is: Should I use both on the same page, and if so, how?
When I use both, then an error filtered by a ComponentFeedbackPanel is
also filtered by FeedbackPanel and the error is displayed twice, in
both panels.
I tried to avoid this by:
IFeedbackMessageFilter filter = new IFeedbackMessageFilter(){
public boolean accept(FeedbackMessage message) {
return ! message.isRendered();
}
};
FeedbackPanel feedbackPanel = new FeedbackPanel(feedback, filter);
ComponentFeedbackPanel componenFeedbackPanel = new
ComponentFeedbackPanel(fedbackText, textField);
But this simple approach fails because FeedbackPanel gets the message
before ComponentFeedbackPanel :(
I would rather not add a not-to-do list to FeedbackPanel, as I would
really like to keep this simple. Especially because
message.isRendered() looks useful.
Any ideas?
Many thanks.

Re: Posting A Form To NonWicket
Balaji, If I understand you correctly, you want that the browser is redirected to the response of a post request to site B after the user only sent a post request to site A. This is really not a Wicket question. Web browsers cannot be directed to respond like this unless you send a page with your form with the action URL of site B, AND let JavaScript post it, started from the body onload() event or similar. But the users might not universally accept to post to another site without having clicket a button. So you might as well include a button for them to click. If you don't feel comfortable with this solution, then as others pointed out, you need to let the server app post to the other site. But that may be messy again, because the response is not necessarily suited to be read by a computer. If nothing of the above appeals to you, and I wouldn't be surprised about that, then you might want to reconsider how to exchange data with the other site. In any case, Wicket seems to support everything that can possibly be asked for in this scenario. The details of it have been written in previous responses.

Complications with loadable detachable models
Hi It appears that I am fighting against the framework that limits my choices when I start using LDMs (LoadableDetachableModel). Many examples in the framework documentation don't use LDMs. For simplicity, they assume that the domain object e.g. person is available to a model in an instance variable. But LDM use is Wicket best practice. So if I switch to LDMs, then I remove instance variables containing domain objects to avoid their leakage into the session. As a consequence of that, I must use wrapped PropertyModels that use reflection and that are not refactor safe. In addition, in onSubmit() methods, I have to manually extract the domain object from the model. If I use simple custom models per form field, overriding org.apache.wicket.model.Model with inner classes, then I have to manually extract the domain object from the LDM for each setObject(...) and getObject() method. To avoid these obstacles I would keep for convenience a transient instance of the domain object. In onDetach(), I would set it to null to avoid leakage into the session. But how do I initialize it? I can do it in a Panel's constructor, but in a stateful page, the constructor of a Panel is not called when it is taken out of the session. I found Page.onPageAttached() interesting for that, but I cannot use it with a Panel sub class that is not hard-wired into the Page. How can I use LDMs without this conflict? In the described scenario, Wicket is really difficult to use, and that is because one has to be so careful about domain objects leaking into the session.

Help with Back Button Use Case
Hi, Wicket has excellent support of versioning due to its server side state, and not only that, it is well documented e.g. in the feature list, wiki. In my use case, versioning is controlled with the objective of turning it off with Component#setVersioned(false) on page level. This appears to work for me in the following scenarios: a) Page URL is non-bookmarkable, no explicit mount() for the page ?wicket:interface=:2:menu:edit-link::ILinkListener:: 1 - ?wicket:interface=:3 1 - ?wicket:interface=:3 1 - ?wicket:interface=:3 b) Page URL is bookmarkable, mount() with HybridUrlCodingStrategy /edit 1 - /edit.3 1 - /edit.3 1 - /edit.3 The page changes state, i.e. it shows error messages and panels are replaced while the user interacts with it. When the user presses the back button, then the user does not get an old version of the page but gets the page linking to it, which is good in this use case. The following scenario is bad for the use case: c) Page URL is bookmarkable, no explicit mount() for the page ?wicket:bookmarkablePage=:EditPage 1 - ?wicket:bookmarkablePage=:EditPage 2 - ?wicket:interface=:3 2 - ?wicket:interface=:3 The back button shows the user 2 diferent versions of the page, the latest one and the first. My question is how Wicket can support this use case with bookmarkable URLs bu without expensive page mounts. I want that because with scenario b), I seem to need one mount for every single page. With the number of mounts increasing, performance is getting worse. Isn't there a cheap global mount with a URL coding strategy that does not have that performance penalty, and that can be applied to all pages while producting the same result as in scenario b)?

Browser back, Panel replacement
Hi, I have been using panel replacement instead of multiple different pages as a way to avoid a kind of back button problem but I am not happy with my solution. The objective is to prevent the user from going back after an update to previous pages/versions of the page containing state of domain data which really does not exist anymore. This worked without AJAX when using HybridUrlCodingStrategy. Because of a high number of pages, I want to get away from any WebRequestCodingStrategy because of the Performance hint in IRequestTargetUrlCodingStrategy#getMountEncoder. I don't mind ugly URLs. When I remove the HybridUrlCodingStrategy then the approach does not seem to work anymore. Also I am suspicous of any missing panel crashes on navigation with the panel replacement approach. How can I meet my objective? Is there a Wicket best practice approach for this? I feel I am running round in circles considering options such as IRequestCycleSettings.RenderStrategy, setVersioned(false). My possibly oversimplified thought is that Wicket keeps changing page state on the server and via HTTP post redirect back to the same page there would never be a browser back option because the same page cannot have multiple subsequent entries in the browser history. I feel that this is such an obvious and common problem - I hope this has already been written about and I just missed the article.

Re: Serializable check
Igor,
Thanks very much for your suggestion which I followed.
I have overridden it and that is an improvement but still not good.
ListDataProvider dataProvider = new ListDataProvider(myList){
@Override
public IModelMyEntity model(Object object)
{
return new DetachableMyEntityModel((MyEntity) object);
}
};
SerializableChecker does a nice job spotting:
...
private final java.util.List
org.apache.wicket.markup.repeater.data.ListDataProvider.list[write:1]
[class=[Ljava.lang.Object;]
private final java.util.List
org.apache.wicket.markup.repeater.data.ListDataProvider.list[write:1][0]
[class=MyEntity] - field that is not serializable
I guess that private final ListT list; of ListDataProvider wants to
be serialized into the session which we don't want?
I am trying to apply best practice - may be I should not be using
ListDataProvider?

instead of using listdataprovider you should use a dataprovider in

Re: Serializable check
Thanks again Igor.
I have switched to plain IDataProvider as suggested, although I have
to admit that I still have to look at the phonebook example.
Again, IDataProvider is an improvement, but still not good.
It appears that SerializableChecker is complaining about a volatile
field not being Serializable. Is this a bug or do I miss anything?
I think that SerializableChecker is a wondeful tool, that is why I am
persevering:
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException:
Unable to serialize class: MyEntity
...
private volatile java.util.List MyEntityDataProvider.entities
[class=java.util.Vector]
...
public class MyEntityDataProvider implements IDataProviderMyEntity{
private final Integer searchId;
private volatile ListMyEntity entities;
public MyEntityDataProvider(Integer searchId) {
this(searchId, null);
}
public MyEntityDataProvider(Integer searchId, ListMyEntity
entities) {
this.searchId = searchId;
this.entities = entities;
}
@Override
public IteratorMyEntity iterator(int first, int count)
{
return entities.iterator();
}
@Override
public int size()
{
if(this.entities == null){

this.entities = sessionBean.getMyEntities(this.searchId);
}
return this.entities.size();

which is what I did.
It works nicely until I hit a problem with ListDataProvider in
DataView, where I get an exception even if I use LDMs:
java.lang.ClassCastException: MyEntyty cannot be cast to
java.io.Serializable at
org.apache.wicket.markup.repeater.data.ListDataProvider.model(ListDataProvider.java:35)
It appears to me that the approach has a conflict with framework
classes.
What is the best way to spot session memory issues without hitting
this problem?
Many thanks,
Bernard

Re: Serializable check
Igor,
Creating the list of entities exclusively inside iterator() requires
two database calls for retrieving a list for a single request, the
additional call being required for the size() method that is called
prior to iterator(). That is an unfortunate side effect of this API.
I don't have a problem with that as I work around it, as others have
done before me, by fetching the data eagerly with the size() method
and then caching it in a volatile field for use by iterator().
I just can't afford to make two database calls.
So I wonder, what is the situation with SerializableChecker
complaining about that volatile field not being Serializable. Is this
a bug or do I miss anything?
Should I use something else instead of IDataProvider?
Many thanks.
Bernard

Re: Serializable check
Hi James, Thanks for the question. In this case, yes. In other cases where I use IDataProvider, no. I know that IDataProvider provides functionality for pagination which I don't use here, that is why I ignored it. I must admit I have a few issues with IDataProvider but I don't want to distract from the original issue. So I wonder, what is the situation with SerializableChecker complaining about that volatile field not being Serializable. Is this a bug or do I miss anything? Should I use something else instead of IDataProvider? I just want to retrieve a list from the database, display it in a table while not having to deal with fake Serializable issues when I remove the Serializable interface from the business object. I have to do this to check the application for leaks of that business object into the session. Many thanks.

Re: Serializable check
Thanks very much!
As pointed out, I was incorrectly using the keyword volatile instead
of transient. All is well now with IDataProvider and
SerializableChecker.
SerializableChecker is great!

IDataProvider for growing Result Size
Hi, I am seeking some help or links to documentation with IDataProvider for DataView. In my use case the size of the data grows while the user clicks through list pages. I wrote an IDataProvider implementation that progressively returns larger values with the size() method. However it fails due to the size growing, if the user clicks on the last page. That is because DataView limits itself understandably, by only requesting as many rows as the last invocation of size() tells it are available. But this limitation is unnecessary. What is needed is that it keeps filling the page until the Iterator for IDataProvider.iterator(int first, int count) returns false with hasNext(), or until its page is full, in that case displaying a link to the next page, ignoring the fact that size() is no longer accurate. I hope that an easy solution for this requirement exists as I think that there is no conflict with out-of-the-box correct behavior. Again, very specifically, during the same cycle, after the underestimated size() result, the iterator may return more data than expected, and that excess data should be consumed normally in such a way that the user can continue moving forward to subsequent pages as long as more data becomes available.

Re: How do you achieve persistency
Peter, If you already used Hibernate, then you probalbly don't want to deal with raw JDBC anymore. JPA is the new standard, and even Hibernate is compatible with it. I use NetBeans + EJB 3.0 including JPA + Wicket which looks like an easy combination to me. On that level, if your persistence technology is not performing, then you can replace it with something else easily, e.g. OpenJPA, EclipseLink. I get the impression that out of a number of persistence frameworks some will become legacy over time while JPA becomes mainstream. I have read comments that due to the emergence of JPA, iBatis support has shifted efforts away from Java, towards MS .NET. I would not be distracted by any impression that part of the Wicket community may be biased against EJB and JPA.

Page redirect after POST
Hi, With forms on Wicket pages, it appears that on submit which is HTTP POST, Wicket redirects to the same page (the page from where the data was sent) ad this is how we show feedback on the form page. How is it possible to send the rendered form page back to the broser as a direct response to the POST, not via a redirect? Many thanks.
