I've got it redirecting to the login page whenever you try to invoke a @Secured method. But, once you login, it doesn't exactly go back and try to do what you were trying to do. It will just take you back to the page where you were trying to do it (a limitation of how Wicket handles the redirectToInterceptPage).

I actually had to Google that one. But, yes, that is the general consensus that I've seen. If you wanted to write a page that showed the different ways that you mentioned, that would be fine.

FWIW, I did search the list, before posting. I found a lot of disagreement about this topic, no resolution, and mostly threads that just trailed off. I was hoping that perhaps there was a consensus pointing to a best practice with respect to creating component hierarchies in wicket that works around the problem of constructors in java, but that does not seem to be the case. Some people advocate onBeforeRender with checks to make sure it's the first time, some people advocated adding an onBeforeFirstRender() to the framework, which never made it in. Some use init() methods like I posted, and some use factory patterns. If the consensus is just that TMTOWTDI, that's fine too I suppose, but it will result in this thread resurfacing bi-monthly.

lazily loaded table structure?
Hi, I want to display a table structure, however the data retrieving takes a certain time. Currently I use the AjaxLazyLoadPanel to display all results at once. But in future I'd like to to immediately display it on the page when it is retrieved. So I need some kind of table where I can add rows via Ajax *AND* reorder the items (because they are not retrieved in the final order). Do you know of any components that can be helpful for this task?

Re: Bookmarkable fallback ajax link
googlebot does not support cookies, so your container will add jsessionid into the url. so unless googlebot specifically ignores jsessionid (which doesnt look to be the case because there are plenty links in google with jsessionid) it should all work. -igor On Thu, May 14, 2009 at 9:19 AM, John wrote: > Hi, > > I want googlebot to be able to see content that is shown to normal browsers > using ajax.

Re: Bookmarkable fallback ajax link
Is your Ajax link redirecting you to another page? Or is it swapping something out on the page? I suppose you could create a bookmarkable link and add the ajax behavior to it, but this seems counterintuitive because it is unlikely that you have an ajax link that is simply redirecting you to a new page. So, it seems like this would be creating two entirely separate code paths. -- Jeremy Thomerson http://www.wickettraining.com On Thu, May 14, 2009 at 11:19 AM, John wrote: > Hi, > > I want googlebot to be able to see content that is shown to normal browsers > using ajax.

Use injection. The difference is that there is no way to override the implementation of the static accessor / singleton for testing functionality.

Re: Component creation and initialization
Documentation is always welcome. This is a very active list (one of
the most active that I've seen with an open source project) where the
core devs spend a lot of quality time answering questions. There's
not enough hours in the day for us to also add that to documentation
or provide everyone with links to documentation when so much of it is
available by using smart searches on the plethora of available list
searching sites. I use Nabble extensively. So, you will hear "search
the list" quite a bit. Interestingly, in the long-standing defacto
article on asking smart questions, the very first thing it says to do
is to search the forums [1].
So, the long and short of it is that we need folks like yourself who
may not spend as much time answering questions on the list but will
take the initiative to pull out the useful tidbits and document them
on the wiki, organize the wiki so that it's easier to navigate, etc.
Many times that is thankless work, but it is appreciated nonetheless.

I've only been on the wicket list for a few months, and I can
understand the annoyance of bringing up a subject that's perhaps been
beaten to death, but to me that means the resulting consensus to be
documented in the wiki, rather than pointing users to "search the
list." So whatever comes out of this thread, I'll add it to the wiki
(unless it's already there, in which case I apologise.)
This isn't just a matter of whether Wicket internally calls
overridable methods.
What ends up happening (only in my experience) is that inheritance for
pages ends up needing you to create your own internal init() mechanism
in order to ensure that subclasses are ready to effectively override
methods for base class component creation. I'm not suggesting that
Wicket provide this type of init() mechanism, but in my experience it
is a pattern that crops up, and it should be documented as such. If
it is already documented, my apologies. If it's an anti-pattern,
what's the alternative?

public Template(PageParameters params) {

}
}
This same pattern evolves in my experience even if you are using
panels for templating, because you need the base class to add() the
panel, and the subclass wants to override which panel to add, but it
can't know what it needs to know in the override unless an init method
has given it a chance to access PageParameters.

Is there a JIRA issue for that?
If yes, I will vote for it and suggest to change the name to something

Re: objectautocomplete on a form with CompoundPropertyModel
hmm true, I think it's because it's ajax and actually get set before
the form are submited. I agree it would be nice if it acted exactly
like normal form, but I guess the way it are now allows much more
flexibility, however it should be possible to do the other aswell.

You do something like this:
// compound model
private final IModel cityModel = new
PropertyModel(
searchWrapper, "cityId");
builderCity
.updateOnSelectionChange(new
ObjectAutoCompleteSelectionChangeListener() {
public void
selectionChanged(AjaxRequestTarget target,

model) {
cityModel.setObject(model.getObject());
}
});
So it does not update on submit, but instead onSelectionChange of the
builder..

Re: Newbie-Problem: Wicket/Maven/Jetty: FileNotFoundException?
Note that this is a maven problem.
Apparently maven does not use the correct 'home' directory. You can
override the home directory set by setting an environment variable. I
think its called M2_REPO.

Erik.

ROSSV01 is the name of the networkserver where my userdata is stored.
I have no clue
why Maven(?) chose that directory... However the URL is false:
Right URL:

Wrong URL:
\\ROSSV01\ROSSV01\Users\mypersonalusername\.m2\...
So I'm pretty stuck here. Is it a Wicket error? Is it a Maven error?
Jetty error? Where could I change the URL using eclipse?
Right now I am pretty confused here...
Would be great if somebody can help me out...

Bookmarkable fallback ajax link
Hi, I want googlebot to be able to see content that is shown to normal browsers using ajax. I use a fallback ajax link but because googlebot does not use sessions the links need to be bookmarkable. The problem seems to be because the link contains an ajax behaviour it is considered stateful. Is there anyway to achieve this? thanks, John - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Sounds like a nicer solution! I'll look into doing something like that myself, being a Wicket newbie it might take me a while though.

Re: Spring Security's method security and Wicket
The catching AuthenticationException and returning false is something I'm not familiar with. I don't think I've mentioned it? Please refresh my memory, maybe I have mentioned it. ;-) I was talking about Spring throwing a AuthenticationCredentialsNotFoundException, when the exception goes back to Wicket it swallows the exception (and shows it to the user) and I was wondering if there is a possibility to let that specific exception through. By letting it through (ie re-throwing it without encapsulating it or modifying it) Spring can handle it and I think it will work as advertised by Spring. My question 2 was essentially if this is something one wants to do with Wicket. Or if there could be any nasty surprises along the way? One such nasty surprise might be: 1. Spring records the request. 2. Wicket recieves the request, it's a session relative page. 3. Wicket does its thing and some logic written by "you" is executed. 4. Your code calls a Spring bean through Wicket-Spring-IoC. 5. Spring Security intercept the method call and performs an authrorization check. It turns out the user isn't logged in! A AuthenticationCredentialsNotFoundException is thrown. 6. Wicket catches the AuthenticationCredentialsNotFoundException but re-throws it exactly as it were (by solving my question 1). 7. Spring catches the exception, let's the user log in and simulates the previously recorded request. 8. The request is for the session relative page from earlier [see 2 above]. But that object no longer exists as the AuthenticationCredentialsNotFoundException was thrown [see 5 above]. Maybe we will get a NullPointerException here. Could such nasty surprises happen? If so, then it might be better to turn the user to a access denied page when a @Secured method is found and the user isn't logged in or lacks the sufficient role(s). It still involves catching the Spring Security exception I guess, but logging in and re-sending the request is not an option. Thoughts?

RE: May be useful for projects deciding between JSF and Wicket
Hmm, Not sure if I can convince my boss (or maybe even me myself) by this blog entry. The title is subjective at best to start with and to open up with blog entries from 5 years ago is not giving it more credibility. I have worked with jsf (myfaces and icefaces) on 2 projects and to be honest I forced it down the throat of the freelancers. In the end it worked allright (for intranet, we havent tested it for more than 10 concurrent users). We have definitely have had our share of problems. However to change architecture with a group of people used to it is a brave or even stupid action. I have seen quite some freelancers come and go with only one thing on their agenda: pimping up their cv. It went from struts to jsf, from jdbc, ejb1/ejb2, hibernate and jpa all on Websphere (the only stable factor, giggle). Now we should refactor again to wicket or tapestry or whatever. The big thing with JSF is, it is mainstream IBM, Oracle and Sun love it and so does management (like it or not). I do realize i'm saying this on the wicket forum, where I follow some of the discussions and I hope to take part in it at a later stage. My objective is first to play with it myself (on a hobby project at home) and see how well it will fit our needs. What I can say at this point in favor of Wicket is the enormous enthusiastic and capable crowd supporting it. Problems with jsf are hard to solve just by lack of support, support which is strangely enough adverted big time by the large companies. regards, jeroen. -Oorspronkelijk bericht- Van: Peter Thomas [mailto:ptrtho...@gmail.com] Verzonden: vr 5/15/2009 8:14 Aan: users@wicket.apache.org Onderwerp: May be useful for projects deciding between JSF and Wicket Hi, I blogged a fairly large collection of links to discussions about the issues with JSF in general.
