[Wicket-user] Getting hold of the servlet request in a wicket WebPage
Hi, I have a servlet filter which analyses the servlet request and then sets a variable to it, I need access to this inside a wicket web page. How can I get hold of the HttpServletRequest object (or attributes set in it) from a wicket page? Thanks Rob - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Wicket-user] Migrate to 1.3 - custom label/link problem
I have a problem migrating from Wicket 1.2.6 to 1.3
I have a custom LabelLink component that I used to generate links, including
labels, in a data table.
This worked fine in 1.2.6, but now I get the following error:
unable to find component with path
forumBrowserForm:forums:rows:1:cells:1:cell:link on page
When debugging I noticed the onLinkClicked was never called on my LabelLink.
Instead the page
constructor is called again.
Here is the LabelLink component:
http://papernapkin.org/pastebin/view/933
1. public abstract class LabelLink extends Label
2. implements ILinkListener
3. {
4.
5. protected LabelLink(final String id, String label)
6. {
7. super(id, label);
8. }
9.
10. protected LabelLink(final String id, IModel model)
11. {
12. super(id, model);
13. }
14.
15. protected void onComponentTag(final ComponentTag tag)
16. {
17. tag.setName(a);
18. tag.put(href, urlFor(ILinkListener.INTERFACE));
19. }
20.
21. protected void onComponentTagBody(final MarkupStream markupStream,
final ComponentTag openTag)
22. {
23. replaceComponentTagBody(markupStream, openTag,
getModelObjectAsString());
24. }
25.
26. public final void onLinkClicked()
27. {
28. onClick();
29. }
30.
31. public abstract void onClick();
32.
33. }
The LabelLink works fine on a page, but not when I use it inside a column of
a data table.
For example when I make a panel inside an AbstractColumn
When I try to put a panel in the column with a normal Link and Label it
works.
But when I put my LinkLabel in it it does not work.
The hrefs that are generated are different, and probably the cause that my
onLinkClicked is not called.

[Wicket-user] No get method defined for expression recorder when using Palette and CompoundPropertyModel
Greetings,
I have migrated by application to the wicket beta2 and I have experienced an
apparent change in the functionality of CompoundPropertyModels.
I have a simple page with constructor code similar to the following code:
public TestPage() {
setModel(new CompoundPropertyModel(author));
add(new Label(firstName));
add(new Label(lastName));
add(new Palette(lstAuthors, new Model(), new Model(new String[]
{Michael, John, James, Suzy, Lucy}), new ChoiceRenderer(), 5,
false));
}
with the appropriate HTML page.
However, when displaying this page, I get the
No get method defined for class: class com.blahblah.Author expression:
recorder
Root cause:
org.apache.wicket.WicketRuntimeException: No get method defined for class:
class com.blahblah.Author expression: recorder
It seems that the recorder pseudocomponent in the Palette component has no
inherent model, therefore it inherits it from the parent compound model.
This error does not seem to appear in the beta1.
Was there some kind of CompoundPropertyModel change between beta1 and beta2?

Re: [Wicket-user] [Wicket-User] Spring+Hibernate questions
Thanks for your replies everyone. I think I can make an informed decision now about what to do in each case. I like the flexibility of the @SpringBean and the simplicity of the application object, probably with seperate objects holding the DAOs and services, so not to bloat the application object. I think I will investigate more open the OpenSessionInView to see what EXACTLY that thing is doing. Perhaps I will ask more about that later. The pros and cons of both approaches are discussed in the wiki as well: http://cwiki.apache.org/WICKET/spring.html Yes I read this before posting. I think it would be more clear if it's mentioned that the InjectorHolder.getInjector().inject(this); can be used in any of your classes, such as models, and not just components. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Is there a good Wicket example project I can look at, besides phonebook, that uses Spring and Hibernate? I am interested in the right set-up. You could also look at the Databinder project. It includes some nice examples too. Ok thanks! I also have some questions about OpenSessionInViewFilter, which probably are off-topic, but hope someone wants to help anyway. There seems to be quite some disagreements about whether using OpenSessionInViewFilter is a good thing or not. What does the Wicket team/users think about it? I have also used OSIVF on a project. And you really have to be carefull here. Hibernate has some nasty exceptions that easily will be thrown at you. Especially Lazyexception session closed or... object with same id is already loaded in session Unfortunately I do not know what to be careful for yet :) I came to the conclusion that is was much easier to copy you hibernate objects into viewbeans which is designed with wicket in mind. So above the service layer you have view bean. And under the service layer you have hibernateobjects (domain objects). I would be happy to hear others comments on this one. Do you have an example for this? It's difficult to think of what those viewbeans are. They don't have associations? You know the answer(s) to the section below? If I understand correctly, and please correct me if I'm wrong, by using the OpenSessionInViewFilter you get a new transaction at the start of every request, which commits or rollbacks at the end. This is so that lazy associations, which are accessed outside explicit transactions, such as in Wicket Page classes, are initialized and don't throw an exception. So what kind of transaction exactly is created by the OpenSessionInViewFilter? (propagation, isolation?) Can I use it only for reading? - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits. Just data.

would be better than using the application to hold the DAOs.

this is better because if you use applications to hold non-proxied daos
you have to be very careful not to leave a reference to it anywhere. because
dependencies injected throgh @SpringBean are special proxies you dont have
to worry about it because the proxies can be safely serialized.
I do understand that. But isn't it very easy to avoid it? For example the
PersonClass would be something like this:
class PersonModel extends LoadableDetachableModel {
private final long id;
public PersonModel(long id) {
this.id=id;
}
private PersonDao getDao() {
return MyApplication.get().getPersonDao();
...
}
With this getter there is no temptation to save the DAO as a field.

[Wicket-user] File Releases suggestions
When a new version is released I would like to get all the new zip files quickly. However there are 11 zip files and somehow the download is always set to some non-working mirror which I have to change manually. Those are a lot of clicks. I would really enjoy if there is a mega-zip file release which contains all the other zip files or directories. Another suggestion is the filename of the releases. They all have the -bin part, even though they include source and documentation. Some other open source projects use the -bin filename part too, but they usually have separate releases with -src. So why not have filenames such as wicket-1.2.6.zip - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.

Re: [Wicket-user] ListView class cast exception
Hello,
your getUsers() method looks suspicious - it seems to create list of strings
(not Users). Particularly, you add Strings retrieved from the resultset into
the list.
retval.add(rs.getString(1));
Therefore the ListView component gets passed the list of Strings retrieved
from the first column of table.

Re: [Wicket-user] How to display applet in wicket?
Hello,
in my experience, the most frequent problems with applets are connected with
classpath problems. Could you have a look into the Java Console output and
search for the potential ClassNotFoundError stack traces? (If I remember
correctly, you could right click on the applet that failed loading and use
'Show Java Console' from the popup menu).
Besides that, this is an applet page from our project:
HTML template:
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN

Corresponding Java class:

public UserProfileAppletPage() {

I would make a the simplest possible html page including your applet tag

by wicket. If they are the same, you should observe exactly the same
result in your browser in both cases.

Re: [Wicket-user] How to display applet in wicket?
One problem, which could arise, is the URL from which is the graph.class loaded. When you've got your applet page on http://server.com/page/applet.html, browser JVM willl try to load graph.class from http://server.com/page/graph.class URL. Also make sure that you have a correct case (Java classes should start with an uppercase letter, therefore I think it is better to have applect code=Graph.class.. and class called Graph). However, if you specify the JAR files in the archive attribute, your classes will be loaded from the specified JARs. There can be another hiccup dealing with URL mounting. In our project we have mounted the Wicket webapplication on the url-pattern/app/*/url-pattern. Therefore our applet page has URL http://[servername]:8080/[appname]/app?wicket:bookmarkablePage=:uinf.wid.tools.UserProfileApplet, which means that the JAR files are loaded from the http://[servername]:8080/[appname] directory, i. e. from JAR files which are located in the directory just above the WEB-INF. If your webpage is mounted (for example to http://[servername]:8080/[appname]/app/userprofile), you could come across JAR loading problems, because JVM will try to load JAR/CLASS file from that http://[servername]:8080/[appname]/app/userprofile, which does not correspond to any server directory, therefore it will not find your JARs/CLASSes. edward durai wrote: Hi to all, I have one graph.java file.

[Wicket-user] Inner classes question
I was wondering if it is unwise to prevent the use of inner classes for models. For example a page creates a model for CheckBox that depends on a list stored in the page. In Wicket examples the list is accessed from the inner model class directly. I do not like having many inner classes in a class. What if I create a seperate model class and pass the list with it in the constructor. The final modifiers will ensure that the reference to the list cannot be changed. Will this cause the list to be serialized twice? Or will it be noticed that it is the same list. Will it cause any other problems, and if so isn't there another way to prevent the use of inner classes? Robert - Take Surveys. Earn Cash.

Contrary to what some people say on The Server Side etc, Wicket and Tapestry are very different frameworks. This means that not everything can be mapped from one framework to the other. Yes, I have noticed that :) Tapestry's services seem to be pretty particular for that framework. And without those services there is not much left in Tapestry. The best way to go here is to forget about the facilities you had in Tapestry, but just focus on what you want to accomplish. It will be easier for us to help you out with specific use cases, or you might be able to figure it out yourself. What I need is a way to do have a call from javascript to trigger some action. Both through normal HTTP requests and XMLHTTP, but I will focus on the normal part first. There is no associated component in the page. It is just a javascript controller object, that wants to send commands to my application. The request cycle is enough for me to continue at that point. Something else related to this is if I can have a Link where I can add parameters to in javascript. Looking at Wicket I get the feeling that the state is purely something that is kept in pages and components with its associated models. There does not seem to be room for the client browser to keep any state. I actually have a whole model-view-controller system in javascript for certain complicated situations. I tried to look at how a Tree component works, and see if I could learn something by looking at how it's called. But that part was just magic to me :) Robert - Take Surveys. Earn Cash.

Re: [Wicket-user] Tapestry - Wicket | Action Service
I tried to look at those listeners. If I understand correctly you always
need to be a component to be a listener.
Each listener interface must have 1 method with 0 parameters. So it means
all state must be kept in the component.
You cannot pass any parameters to it? So in the case of a PageLink you must
know which page to render, before
the link has been clicked?
I'm just trying to sort things out in my head.
I would like to know more about how Wicket knows which ILinkListener to call
when a link is clicked. I found the apidocs
to be rather abstract about listeners. It felt like you already had to know
how they work before you can understand the docs.
Please don't take any off this as criticism against Wicket. I'm sure it is a
great project. And I will be using it in the future.
I'm just not sure if I should convert this project from Tapestry to Wicket.
I am beginning to think that it's not a good idea.

Re: [Wicket-user] What's the best way of doing menus in Wicket?
I have tried to use dropdown menu in one of my projects. NavMenu has been broken in that time (and I didn't figure out how to patch it) and my effort in integrating TigraMenu wasn't succesfull either. Finally I have used the approach which uses a pure CSS menu which is based on the :hover class. The menu is composed of multiple nested span tags (which are mapped to Wicket Label-s or Link-s). However, this approach requires you to know the structure of the menu beforehand and may pose a limitation when you require menu items which changes at runtime dynamically. (There was another slight glitch: in IE this approach requires css-hover.htc script, which may be disabled on some browsers due tu security reasons). However, this approach has suited me well. Eelco Hillenius wrote: The big question there is whether you know all items beforehand or not. If yes, integrating with any javascript library is easy. If not, you need a tree, and probably can best look at that component or navmenu (https://svn.sourceforge.net/svnroot/wicket-stuff/branches/wicket-1.3/wicket-contrib-navmenu) which is deprecated (won't be supported) but nevertheless may give you an idea. The second big question is: what are you going to do with these items: component replacements or do links point to bookmarkable pages? I'd really love to see someone contribute a nice component for this based on bookmarkable pages and a tree. navmenu was a step in that direction, but the API is't great. Eelco On 3/7/07, Thomas R.

Re: [Wicket-user] RequestCycle ThreadLocal
Well, I am converting an existing Tapestry application to Wicket (due to performance and stability problems). The architecture is done is such a way that it is necessary to render responses in a different thread than where the original request comes in. The web application has to deal with asynchronous communication with a server. I will give you an example. The browser sends a request that it wants to submit X. The web application receives this and put task A on the event queue that sends it to the server application. In the meantime task A waits. The server application then sends a request to the web application that it needs information about Y. The web application retrieves the current cycle and renders a response so the user can answer the question about Y. And it continues like that when finally task A gets its response from the server and renders in a request cycle other than the one causing the request. This architecture existed before any web application was developed for it. Robert On 3/2/07, Juergen Donnerstag [EMAIL PROTECTED] wrote: Why Do you want to create a Page in a separate thread?

Re: [Wicket-user] DropDownChoice confusion
The documentation might be a little scattered, however is a separate topic.
Nonetheless, the Wicket Library site features most of the Wicket components
and examples of their usage: e. g. DropDownChoice is demonstrated (along
with the IChoiceRenderer) on the
http://www.wicket-library.com/wicket-examples/compref?wicket:bookmarkablePage=:wicket.examples.compref.DropDownChoicePage

Which of course makes perfect sense...
I'm sorry if I come across as crash, it's because I'm very annoyed. I
thought Wicket was the coolest Java framework out there, but now that I've
used it for 2 weeks on, I can't say that anymore. Every time I've moved on
to the next part of my website, it takes me 2+ hours to figure out how,
and
I'm not talking about entire pages, I'm talking about components of pages.
A
select, an Ajax-ified form, etc. Why do I have to deal with
IChoiceRenderers? Besides how the documentation doesn't tell me how to use
the thing, nor do the examples explain how it works, just here ya go,
copy
this. It just doesn't make sense.
Back to the matter at hand, does anyone have example code using
wicket-extensions Select and SelectOptions? There is absolutely NO usage
documentation on getting all that working together.
Anyway, sorry about the rant, I'm just getting more disappointed with
Wicket
in general. It may be different than other Java frameworks, but I cannot
say
that it's any better. I like the idea, I like some of the implementation
of
it (how Ajaxing components work, best I've seen), but using the framework
has been an exercise in frustration from day 2.
So I'll head back to banging on the DropDownChoice, I'll get it
eventually,
though I'm open for suggestions.

Why is nothing in Wicket obvious?
I want:
select ...
option value=AND/option
option value=|OR/option
/select
My model has a 'gated' field that is either '' or '|'
Why can't I have:
add(new DropDownChoice(gated, model, {AND, OR}, {, |});
or better yet:
add(new DropDownChoice(gated, model, { {, AND}, {|, OR}});
(assuming properly created arrays, of course)?
How is this supposed to work?

[Wicket-user] Session is valid?
Hi, Is there a way to see if a session is still valid. I could only find the private sessionInvalidated so that's not available. One other related question is how to deal with a case like this: A user loads the login page and goes away for a while. Later he comes back and tries to login. However at that point the session has expired and receives this message when trying to log in. Is there some way to prevent this from happening? Robert - Take Surveys. Earn Cash.

component.add(TextTemplateHeaderContributor.forJavaScript

}
The first time the page is renderer I can see the javascript being added,
however the second time the javascript is nowhere to be found. which of
course results in a javascript error when clicking a button that has an

[Wicket-user] Pro Wicket - Form.process()
Hi, Page 96 of the Pro Wicket book describes how discouraging it is that you lose your initial selection, because Wicket does not update form component models during Form submission. A getForm().process() is needed in the DropDownChoice.onSelectionChanged() However when testing it (with wicket 1.2.4) I noticed that everything already works fine without it. Has this behaviour been changed since the book has been made and I can assume that the form component models will be updated from now on? Robert - Using Tomcat but need to do more?

Re: [Wicket-user] Pro Wicket and RestartResponseAtInterceptPage question
I don't think it's a convertor problem, because if the user is already logged in, the ConfirmationPage can be reached without a problem. It's only when the user still has to login between the Checkout and Confirmation page. I don't know why it is trying to set something in CheckoutBook anyway. I'm guessing because it is returning to the CheckoutPage instead of ConfirmationPage.

[Wicket-user] Writing byte[] to a WebResponse
Hello I store a lot of MS Word and Excel files as a byte[] into my database. I want to add a feature to download these files from the database again, but I did not find a way to do this in Wicket, without writing the byte[] to a File again. Is there a way to write a byte[] to a WebResponse? I tried the same Code, which is available at the Export Example from Wicket I got my byte[] from the database and then wrote it to a ByteArrayOutputStream.Then I used the toString() method. But if I download the file then I get a lot of conversion errors from MS Word, so I would like to write the byte[] directly. So I tried this method: response.getOutputStream().write(file); But using this I get this error: java.lang.UnsupportedOperationException: Cannot get output stream on BufferedResponse Thanks for any help Robert - Take Surveys.

I subclassed DynamicWebRessource, but I still have the problem that I do not know how to add the RessourceState to my WebResponse for my download link. I found the class ResourceReference but no I did not find out how to use it. Do I have to use the ResourceReferece Class or is there another way to get my download working?

A Java String and a byte array are not always the same thing due to unicode. Subclass wicket.markup.html.DynamicWebResource so that it returns the correct instance of ResourceState (also your own implementation). Among other things, ResourceState is supposed to provide a byte array that is the content of the download. This would be the byte array from your database.

[Wicket-user] Avoid session reuse on login page when previous user doesn't log out
Wicket 1.2.3 User A and B share a computer at an office. User A logs in. Session is setup with account info. User A doesn't log out. User B clicks on his login bookmark, and logs in using the same session (as it wasn't invalidated with a logout) -- the same session is reused. The login process would then need to manually clear any of the user-specific objects that may have been stored in the session (eg, user preferences, whatever was set in the custom session object). A way around this would be for the login page to invalidate the session, but then a submit would have a page expired error. Any graceful way around this in wicket 1.2.3? - Take Surveys. Earn Cash.

How customize your cell table :
You may create a panel which contains only your link :
wicket:panel
a wicket:id=mylinkspan wicket:id=mytext/span/a
/wicket:panel
and in the populateItem:
MyPanel panel = new MyPanel(componentId);
cellItem.add(panel);
And in your panel constructor
MyPanel()
{
add(new BookmarkablePageLink(componentId, Edit.class, new
PageParameters(map)));
add(new Label(mytext, click here));
}
If you wich to add several types of content in your cell (a link, an
image, a blob, a form, ...), or if you wich to select a row and make
actions, it may more interresting to use a ListView.

[Wicket-user] Ajax refresh for Image
Hello,
I'm trying to change the src of an image when the user clicking on a
ajaxLink by this way :
On a panel, I have an icon and a text (a date using DateLabel from
databinder).
When the user clicks on the link,the panel is refresh by :
public void onClick(AjaxRequestTarget target)
{
panel.setModel(new CompoundPropertyModel(photo));
target.addComponent(panel);
}
The date is refreshed. It's ok for the date. But the image doesn't change.
My Panel is built like that :
Photo photo = (Photo) getModelObject();
add(new DateLabel(date, dd/MM/ HH:mm));
if(photo.getAlarm())
add(new Image(alarm, alarm.gif));
else
add(new Image(alarm, blank.png));
So, It can not work. I extended the CompoundPropertyModel to supply the
correct filename to the Image component. So, the ajaxLink will work too.
All will be ok. But It seems the Image doesn't use my model :(
The method onGetObject is called only for the date label.
Do you have any clue, tips or solution ? I think someone I had already
to change images through ajax Link ? How did you do ?
Thanks by advance...

[Wicket-user] Back button, setVisible, isVisible, Submit Button is not Visible
I'm writing a simple Upload File/View File/Delete File panel. It has 3 buttons. 1. Upload - Only visible when no file is stored permissions are correct via isVisible() override. 2. View File - Only visible when a file is already stored via isVisible() override. 3. Delete File - Only visible when a file is already stored permissions are correct via isVisible() override. When I upload a file, the upload button is hidden, the view and delete buttons are visible. However, if I hit back and click upload again I get wicket.WicketRuntimeException: Submit Button is not visible. What I'd like to do is say a file is already uploaded and ignore their file (I think). For remove I'd say No file to remove. Etc. Or just do nothing and render the current display. Maybe if it threw a named exception? Or do I need to use state changes explicitly and call setVisible so that it rolls the page back to that state. Using setVisible is much less convenient that using isVisible for this kind of logic.

[Wicket-user] Re: Back button, setVisible, isVisible, Submit Button is not Visible
Perhaps a flag on the component to specify whether it handles clicks when it is invisible? That would fix the issue and the component would get the click, could check if it whether it is visible / invisible and then act accordingly. I tried turning on versioning and then using setVisible explicitly but it isn't working (at least the way I'd expect it) The version numbers are incrementing but the visibility isn't changing. I am of course many levels deep in panels.. For now I may choose to have the buttons available at all times and that will get around the problem for the present. Thanks.

[Wicket-user] Re: Upload, multipart form, Resin
Specific to the Resin container I think. It handles multipart forms automatically and puts the file path in the request parameters. So the form needs to be specified as multipart/form-data but Wicket shouldn't handle it as a multipart form. A less intrusive fix to get it working is I explicitly specific enctype=multipart/form-data in the markup and I override Form.onComponentTag, call its super, and then call setMultiPart(false) so wicket doesn't handle it as a multipart form.

[Wicket-user] Porting to 1.2 -- using getSession().invalidate()
In 1.1, given a runtime exception of type SecurityException, I'd forward to a special error page that then calls getSession().invalidate() to log the user out. The special error page would render and then the session would be invalidated, causing additional clicks to forward to the login page. In 1.2 my page no longer renders -- it jumps straight to the Page Expired page if I call getSession().invalidate(). I'm using the default render strategy. Is there a preferred way to implement this type of behavior in 1.2? I want to invalidate the session so that the user can't repeatedly request resources that throw SecurityExceptions, but I'd like a page to be rendered prior to the session being invalidated.

[Wicket-user] DatePicker wicket 1.1 IE 6.0 with HTTPS synchronization / blocking issues
Users of our https site using IE 6 have reported that pages that use a DatePicker seem to stall on downloading the images for the datepicker. I've verified and it happens when the images aren't in the browser cache -- sometimes it takes forever to download the images. Haven't noticed the same behavior when not using https with IE, and of course Safari and Firefox work well. When the datepicker is stalled downloading the images, and I click on another page in the app, it behaves as if it is blocked and doesn't respond to my session until all of the images datepicker images have finished downloading (which can take forever). Does 1.1.1 or 1.2 allow static image resources or .css files to be requested by the browser without synchronization/blocking? I've also noticed that IE will request the images again if I mouseover the datepicker window if they haven't downloaded yet, adding to the delay. Of course, the problem can only be replicated under IE -- maybe it requests all of the images at once and causes some sort of strange blocking phenomenon? Any ideas? Does serving up static resources / images in a package cause the session to block? If so, does it need to? Thanks. --- This SF.net email is sponsored by: Splunk Inc.

I would like to enable page level security in my application. I don't want my page to be constructed unless a certain security requirement is met as at present I do a lot of data loading / etc in page constructors (as featured in the wicket examples). It seems a new security policy is in the works to handle this -- IAuthorizationStrategy. In the meantime, what would be a good way to prevent a bookmarkable page from being constructed? Should I provide a new IPageFactory implementation that checks the session for authorization prior to returning a new page, and perhaps swap the page to a denied access or login page if access isn't available? Or should I check out the latest CVS sources and try IAuthorization strategy if it is implemented?

[Wicket-user] Servlet forward to a JSP
I'm exploring the possibility of integrating Wicket into a JSP application. Is it possible to tell Wicket to do a servlet forward to a JSP? I would like to add a few request attributes and then forward to a JSP. The reason I'd like to do a forward VS include is I need to be able to populate request attributes prior to the JSP running. The login page is currently implemented in JSP. Another option would be to refactor the login page, but I'm curious if it is feasibile to attempt the former as I want to use as much of the existing system as possible.

[Wicket-user] Re: Servlet forward to a JSP
If I come up with anything useful I'd be happy to contribute. The JSP I need to forward to requires request attributes, so I don't think the wicket.markup.html.include.Include component will work as from what I understand it is a separate request whose output is then included into the markup? In this case, the result of RedirectPage would be the same as it is a fresh browser request and I need to populate a request with request.setAttribute() and have the JSP be able to retrieve the request attributes. What I'm looking for is a way in Wicket to tell it to finish its processing, not output any markup, and then forward the request to another servlet, not include or redirect. Thanks. On 2005-11-06 15:38:06 -0700, Eelco Hillenius [EMAIL PROTECTED] said: Sure. Use wicket.markup.html.pages.RedirectPage for server-side redirecting to a non-wicket locations.

Is it possible to tell Wicket to do a servlet forward to a JSP? I would like to add a few request attributes and then forward to a JSP. The reason I'd like to do a forward VS include is I need to be able to populate request attributes prior to the JSP running. The login page is currently implemented in JSP. Another option would be to refactor the login page, but I'm curious if it is feasibile to attempt the former as I want to use as much of the existing system as possible.

[Wicket-user] Re: Multiple checkboxes, table columns how-to in Wicket?
Within a form I'm using a detachable model for a ListView that contains business objects loaded directly via JDBC, each of which has a selected flag, rendered in the ListItem as a checkbox. However, when I get to onSubmit in the form, the model is still detached, and therefore the state hasn't been transferred from the form to the model. Therefore, when it renders, it reattaches but the model hasn't changed. What is the best way to fix this? In onSubmit I'd like to delete the records. The reason I use a detachable model is I want each render to have fresh results from the database via JDBC, but perhaps is there is better way? I haven't set optimizedItemRemoval to true because I don't need anything to be validated.
