RE: message internationalization
The label components are not refreshed after changing locale. Do you know why. My guess is that the labels are not using a Locale-aware model like ResourceModel, but instead have been set using construction-time getString() or the like. Another problem is that when I change the locale I refresh the whole page. (target.addComponent(instance);) where instance is my Page class. Remember that you need to use the AjaxFormComponent* classes in order to get form input values submitted to you. Also: try instead to repaint a subset of the page, e.g. wrap most stuff in a WebMarkupContainer. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Freemarker+ExtJS vs Wicket questions
As a Wicket neophyte myself I can't comment on most of this, but we
did just look deeply into the notion of subclassing components for the
purpose of making them render as rich text widgets from ExtJS. Having
just done that I will say that there are ALOT of little hidden nits
and difficulties that come up in such an effort. Wicket and ExtJS
both want to control the rendering of the end markup, so when you
replace the generated markup with Ext widgets, many of Wicket's little
pre-created solutions for various internet use cases breaks. Each
problem is circumventable, but eventually you find yourself almost
writing your own framework rather than extending a framework.
I would really love it if a more experienced Wicket developer took a
serious crack at creating a Wicket extension that worked with rich
internet controls. I get the feeling that my effort failed as much
because I didn't have deep Wicket knowledge as anything else.

Pros:

- Clean HTML code and all logic handled by Java.
- Quick to start building simple apps that fall into the box of the
framework.
- No JScript or HTML/CSS knowledge needed. Can separate easier Frot-end and
Back-end developers -- easier to hire.
Cons:
- On other hand, as Front-end developer this looks weird to me since I feel
like I don't have full control of JScript code.
1) Since Wicket uses Java for generating HTML/CSS/JScript UI controls for
me meaning if I need to tweak those controls outside of their box it maybe
problematic. In my experience any framework good until you start doing
something different from what it was intended and then you can spend more
time trying to do simple out of box thing then using native JScript. Is
there JScript sources for Wicket controls?
2) Prototyping: using Freemarker I can do changes and simply refresh page.
In case of Wicket I need to recompile.
3) Logic blocks: Looks like Wicket allows injection of values into HTML
tags with wicket: attribute but how do you handle block logic like
IF(condition) then {use HTML block1} else { use another HTML block}?
4) Non html data templating: often during page generation I compose some
AJAX data from FreeMarker inside tag. How do I do similar things from
Wicket?
5) Is it harder/simpler to create custom UI controls in Wicket vs using say
Dojo, ExtJS or JQuery?

I'm not sure what exactly you tried but here is how I'd approach it:
- create a Wicket component that purpose is to render just the HTML
needed by the ExtJS component
e.g. div id=someId/div
for this simple HTML snipper you can just use WebMarkupContainer, but
for something more complex you'll need your own Panel
- create a Behavior that should contribute the JS code
this will load the js template, populate it with some options, connect
it to someId and finally just contribute it to the response with
#renderHead()
I would really love it if a more experienced Wicket developer took a
serious crack at creating a Wicket extension that worked with rich
internet controls. I get the feeling that my effort failed as much
because I didn't have deep Wicket knowledge as anything else.
There are several: wiquery, jqwicket, jwicket, wicketstuff-dojo,
wicketstuff-yui, ...
I guess these use different approach to integrate Wicket with the JS
widgets. Pick the one that you like the most and make it better.
There are talks about making official integration of Wicket with
JQuery UI, i.e. maintained by Wicket core developers but so far there
is nothing done on it.

But as you get into it, all kinds of little problems arise. For example, Ext wants it's form in place instead of the basic HTML form, Ext controls often want to tie into a separate data source, making the JS controls breaks alot of Wicket's behaviors which are geared towards markup, and so on. The devil is in the details. As i said, each individual hurdle that presented itself I was able to overcome, but as time went on, I began to feel like I had a package full or workarounds. I would really love it if a more experienced Wicket developer took a serious crack at creating a Wicket extension that worked with rich internet controls. I get the feeling that my effort failed as much because I didn't have deep Wicket knowledge as anything else. There are several: wiquery, jqwicket, jwicket, wicketstuff-dojo, wicketstuff-yui, ... I saw WiQuery and JQWicket...but didn't really seem to me to be geared towards a full integration as much as a collection of random stuff for specific web use cases. I wasn't familiar with the others. I'll go look at those. I guess these use different approach to integrate Wicket with the JS widgets. Pick the one that you like the most and make it better. Perhaps once I am more deeply familiar with Wicket I would be confident enough to try to extend something for public consumption, but I don't really feel experienced enough to do things Wicket's way. And Wicket seems like one of those frameworks that really wants you to know the right way. I probably shouldn't have attempted this until I'd had a few years of development time in Wicket first. But since Ext is basically a component hierarchy and Wicket is basically a component hierarchy, it SEEMED like a perfect fit. And to some extent i still believe it could be...in the hands of a more experienced Wicket developer. There are talks about making official integration of Wicket with JQuery UI, i.e. maintained by Wicket core developers but so far there is nothing done on it. I read some of those threads. I think this would be an excellent idea. Accessibility is a BIG deal for my contract (US Govt), and many jQuery widgets aren't ARIA enabled, so I would gently prod those thinking about it to keep an eye on accessibility if they decided to do this. Try to pick jQuery components that support ARIA. I think the world is going this way. Users expectations of browser interfaces are increasing quickly. If Wicket were to come to market with it's strong object-orientation (the selling feature that attracted my contract), and more rich client features built in (like the various GWT frameworks, but not using that javascript generating methodology), I think it would capture a space most other web frameworks aren't as well positioned to exploit. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: best way to accommodate dynamic properties
I think you can't do this without markup. Put in DB binary data, width
and height and pul it out then and with this data modify markup. If
image doesn't have exif data you don't know dimensions (I think...)

IRequestMapper that ignores page version
Hello, I have a problem similar to the one outlined here: http://apache-wicket.1842946.n4.nabble.com/Migrating-from-1-4-16-to-1-5-RC3-problem-when-trying-to-avoid-pages-caching-not-calling-the-construc-td3463183.html. I have a page that uses a lot of Ajax (and is thus stateful/versioned), but I need its constructor to be called any time the page is requested. Otherwise, if the user lands on the page via the back button, it will not be rendered correctly. Anyway, I'm looking into creating a custom IRequestMapper, per Martin's suggestion in the Nabble thread. However, I don't know where to start. Should I extend one of the existing mappers (e.g. MountedMapper), or should I create an entirely new implementation of IRequestMapper? In either case, how do I make sure that I don't screw up handling of listener links for ajax actions on the page? In other words, how do I create a reliable IRequestMapper for a page that, when requested, always re-renders itself? If there's a different way to accomplish this (i.e. without creating a custom IRequestMapper or making the page stateless), I'd love to know. Thanks for your help! -Allen

Model Not Updated for Empty Fields
For some reason my data model is not being updated when I completely erase an input text field. I'm submitting the form via an AjaxSubmitLink, and the model shows changes to the contents when there ARE contents. And the model correctly shows changes to the field contents when I change the contents. But if completely ERASE the field content, the model does NOT show an empty string. Instead it shows the value before the erasure. The problem occurs regardless TextField.setConvertEmptyInputStringToNull is set to true or false. ** This email and any attachments may contain information that is confidential and/or privileged for the sole use of the intended recipient.

CSRF protection and preserving page mount names
Hello,
I'm migrating from wicket 1.4 to 1.5 and I am looking to port the cross
site request forgery (CSRF) protection from wicket 1.4.
In 1.4, the recommended way[1] is to use CryptedUrlWebRequestCodingStrategy:
// MyWebApplication.java
@Override
protected IRequestCycleProcessor newRequestCycleProcessor()
{
return new WebRequestCycleProcessor()
{
protected IRequestCodingStrategy newRequestCodingStrategy()
{
return new CryptedUrlWebRequestCodingStrategy(new
WebRequestCodingStrategy());
}
};
}
In 1.5, this has been removed and we're asked to use
org.apache.wicket.request.mapper.CryptoMapper[2]
instead:
// MyWebApplication.java
@Override
protected void init()
{
...
mountPage(login, LoginPage.class);
...
// must be last call in init()
IRequestMapper cryptoMapper = new
CryptoMapper(getRootRequestMapper(), this);
setRootRequestMapper(cryptoMapper);
}
While this solves the CSRF problem, there is a big issue with this: there
is no longer a page mapped to login. If this were a quickstart,
http://localhost:8080/login gives a 404.
In wicket 1.4, LoginPage would be accessible via http://localhost:8080/login,
and any other page similarly mounted would give a friendly URL if you
landed on it. The only time anything would be encrypted would be during
form posts, which was perfect because that was the only time I'd need it.
In wicket 1.5, is there a way to bring this behavior back? Or am I doing
something wrong? Or is there another recommended way of protecting against
CSRF attacks?
Thanks for any help,
- Dan

Re: IRequestMapper that ignores page version
Martin,
I had to modify your example to get it to work, as request.getUrl()
actually returns a new Url instance when it's called. Here's what I
settled on:
@Override
public IRequestHandler mapRequest(Request request) {
Request requestToMap = request;
if ((request instanceof WebRequest) !((WebRequest) request).isAjax()) {
PageComponentInfo info = getPageComponentInfo(request.getUrl());
if (info != null) {
Url url = request.getUrl();
url.removeQueryParameters(info.toString());
requestToMap = request.cloneWithUrl(url);
}
}
return super.mapRequest(requestToMap);
}
Does anyone see any issues with this approach?
Thanks!

Hide page version query parameters

Re: ConcurrentModificationException
Hi, I don't see how this may happen. The execution of RequestCycle is single threaded. Do you have RequestCycleListener or something similar where you start another thread and you use the same instance of RequestCycle ?

Wicket version 1.5.3. Any suggestion on how to avoid this? In the init method of sub-class of the WebApplication , I have: IApplicationSettings settings = getApplicationSettings(); settings.setAccessDeniedPage(AccessErr.class); settings.setPageExpiredErrorPage(SessionErr.class); settings.setInternalErrorPage(InternalErr.class); When a session expired, should it invoke the PageExpiredErrorPage? Yes. You make a request to a page, Wicket searches for this page in the stores, doesn't find it and throws PageExpiredException. But, if the request url has the mount path then Wicket will create a new Page instance instead. If you have authentication strategy set up then you go to the Login page, otherwise this page will be rendered. If you are able to reproduce the problem in a quickstart attach it to Jira so we can debug it.
