Extending DropDownChoice
Hi. I would like to save the result of a DropDownChoice in my custom session. But, I am stumped about how to extend it. I had thought that I would @Override the getChoices and onSelectionChanged methods, but Eclipse tells me that "The method onSelectionChanged(Pool) of type PoolSelect must override or implement a supertype method". I am stumped on how to extend this, or even if I should. Any pointers to tips or best practices would be greatly appreciated. In case it is not obvious from the question, I am new to Wicket (but loving it so far). Thanks, Bruce. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [WicketStuff-Scriptaculous] DragNDrop problem in IE6/IE7.
Hi,
Thanx for the hints :)
The problem is solved, but I'm not sure whether Ryan has patched the
scriptaculous code in wicket-stuff svn.

Reading selected radio in validator
Hi, Does someone knows a solution for reading the selected radio button in the validate() of a IFormValidator implementation? The problem I have is that getOutput() on a form component gives the value out of the HTML because no conversion to objects is yet done in the validation step. By the way, I'm using this validation in a wizard step of wicket extensions. Thanks for any help, Rik

can you set a debug point in arrayiteratoradapter and see why it is
getting null array passed in? the line numbers dont line up for my

Re: [WicketStuff-Scriptaculous] DragNDrop problem in IE6/IE7.
Don't know if it is the same issue but I have found the same problem a
while ago (refreshing a component via Ajax) and the problem was
scriptaculous requires to clean up the Droppables if an element was
removed from the DOM tree. So, all I did was add a a clearAll
(JavaScript) method that delete all the Droppables. something like
var Droppables = {
drops: [],
removeAll: function(element) {
this.drops = [];
},
..
and then call it before any Ajax request that recreated the DOM tree. So
that I could safely recreated my component and make them droppables
again. This worked fine for IE7. For Firefox I never found those
problems... There was a note on the web page explaining Droppables that
suggested this idea...
Hope this helps...
Best,
Ernesto

RE: OutOfMemoryError on FilePageSerializingThread
It's sort of a known issue of Tomcat (or Sun JVM? Which one I can't remember exactly). It happens when one does repeated hot redeployment. Tomcat can't clear the permgen space, so the classes get accumulated and eventually permgen space runs out. Something like that :) There's a lot of dicussion about this on Hibernate and Spring forum. It's defintely got nothing to do with Wicket. Passing the JVM option as Igor said is the way to "fix" it.

Re: HybridURLCodingStrategies vs others
mfs, I'm not sure how it works, but the Wicket-based http://papernapkin.org/pastebin/home Pastebin seems to handle URL Coding perfectly clean, the way you describe. The source code is available http://developer.berlios.de/projects/wicketpastebin/ here. It would be sweet if a more experienced programmer than me could explain why and how this works, and possibly document how exactly to replicate the way these smart guys did it.

model inheritence issues :S
Hey guys,
i got this strange issue, what I am doing at the moment is attempting to
pass an objectModel to a child panel thru panel.setModel() but i am getting
a null exception error.
I have run debugger and found that when i retrieve the ModelObject for
imageInfo in Csession, its not null. But when the ContentPanel renders, the
ModelObject IS null :S
any ideas??
public class csession extends Panel
{
Panel content;
public csession (String wicketId, MarkupContainer parent)
{
super(wicketId, parent);
content = new ContentPanel("content", this);
TabModel mod = new TabSessionModel(this);
content.setModel(new PropertyModel(mod, "imageInfo"));
}
}
public class ContentPanel extends Panel
{
Label name;
public ContentPanel (String wicketId, MarkupContainer parent)
{
super(wicketId, parent);
name = new Label("name", this);
name.setModel(new PropertyModel(getModel(), "name"));
}
}

SortableListView and refresh. 2 questions
Hi all,
I am using SortableListView. I can drag and drop and reorder the
items in the list, but I cannot see any ajax message going around. I think I
am missing something as newbie.
SortableListView sortableFirst=crearSortableList("firstlist",
"firstlist_firstlist", listData, "imagenDePerfil", "nombre");
add(sortableFirst);
private SortableListView crearSortableList(String itemList, String item,
List jugadores, final String idImagen, final String idLink){
return new SortableListView(itemList, item, jugadores) {
private static final long serialVersionUID =
1592206924207801984L;
@Override
public void populateItemInternal(final ListItem item) {
final Jugador jugador= (Jugador) item.getModelObject();
RecursosWeb.establecerPerfil2(item, jugador,idImagen,
idLink);
}
};
}
Besides, I added this markup to have the chance to reorder in the list and
with another one, like in this scriptaculous example,
http://wiki.script.aculo.us/scriptaculous/page/print/SortableListsDemo.
I think this already exists but I cant find it, (of course this class is a
mess, I am just testing)
public class MultipleSortableListView extends WebMarkupContainer {
private static final long serialVersionUID = -61199328092575258L;
private SortableListView sortable1;
private SortableListView sortable2;
public MultipleSortableListView(String id, SortableListView sortable1,
SortableListView sortable2) {
super(id);
setSortable1(sortable1);
setSortable2(sortable2);
}
public MultipleSortableListView(String id, String string2,String
string3, List listData, String string4,String string5, List
listData2) {
super(id);
//TODO
}
protected void onRender(MarkupStream markupStream)
{
super.onRender(markupStream);
JavascriptBuilder builder = new JavascriptBuilder();
builder.addLine("Sortable.create('" + getSortable1().getMarkupId() +
"',{dropOnEmpty:true,containment:['" + getSortable1().getMarkupId() + "','"
+ getSortable2().getMarkupId() + "'],constraint:false});");
builder.addLine("Sortable.create('" + getSortable2().getMarkupId() +
"',{dropOnEmpty:true,handle:'handle',containment:['" +
getSortable1().getMarkupId() + "','" + getSortable2().getMarkupId() +
"'],constraint:false});");
getResponse().write(builder.buildScriptTagString());
}
public SortableListView getSortable1() {
return sortable1;
}
public void setSortable1(SortableListView sortable1) {
this.sortable1 = sortable1;
}
public SortableListView getSortable2() {
return sortable2;
}
public void setSortable2(SortableListView sortable2) {
this.sortable2 = sortable2;
}
}
But I got a bug because when one of the list is empty, I can't fill it with
an item anymore.

as i said, what i have shown you is an oversimplification. certainly you can try to load the wicket app first, in reality classes are loaded lazily. so load the wicket app first, use it for a bit to make sure it loads whatever classes it needs, then deploy the first and second ears. that should most likely make it crap out when you start using the last ear's app... -igor On Feb 12, 2008 2:03 PM, Vincenzo Vitale <[EMAIL PROTECTED]> wrote: > It means that if I want to "porove" that Wicket is not the problem, we can > try to load Wicket as the first application and then the others.

Re: Store an object in session
extend wicket's WebSession by your own session class. and add setUserProfile/getUserProvile methods to id. Override Application#newSession method and create your session insteance. Then in your app just do ((MySession)Session.get()).settUserProfile(profile). -Matej On Feb 12, 2008 11:09 PM, Sergey Podatelev <[EMAIL PROTECTED]> wrote: > Hello Wicket people, > > I've a bean containing user information, UserProfile.

Store an object in session
Hello Wicket people, I've a bean containing user information, UserProfile. I want this bean to be accessible for all the pages during user's session, so I guess, I have to store it in the session somehow. There's also a UserProfilePage where UserBean is used as data object for CompoundPropertyModel. And I use Spring along with Wicket in my application. The question is -- what is the best way to store this UserProfile? Should I save it in HttpSessionStore directly through "setAttribute" or configure it as Spring's injected prototype-scoped bean? Or perhaps Wicket has other way to do this which I'm missing? Thanks. -- sp
Re: OutOfMemoryError on FilePageSerializingThread
It means that if I want to "porove" that Wicket is not the problem, we can try to load Wicket as the first application and then the others. Should the problem arise always on the last deployed application? V.

Call for presentations: Wicket Amsterdam Community Meetup 2008 part 1
It is meetup time again! Our last Amsterdam Meetup was a big success and we want to make that a tradition. More than 80 Wicket developers attended the meetup. If you have missed the previous meetup from Nov 30th, 2007 you can see the pictures online [1], or enjoy the presentations [2]. Our next meetup needs presentations to become as successful as the previous one, and we need your help! If you have a nice component library, a business idea, a successful project, written a book or just want to share some ideas concerning Wicket, claim a 30 minute window and share your thoughts! A presentation takes no longer than 30 minutes, and is given in English. Submit your proposal here: http://cwiki.apache.org/confluence/display/WICKET/Wicket+Community+meetups+-+Amsterdam#WicketCommunitymeetups-Amsterdam-program We hope to see you in Amsterdam!

Re: OutOfMemoryError on FilePageSerializingThread
not, this has nothing to do with load. look, your jvm has a preset permgen limit where bytecode is stored. lets say that permgen is allocated 60 megs, and all these numbers are arbitrary. first jboss loads all its jars, which arbitrarily takes 30mb. so after jboss is loaded you have 30mb permgen left. then you deploy the first ear that loads all its jars that take up 15 megs, now you have 30 jboss+15 ear = 15 megs left in permgen then you load your second ear whose jars take up 10 megs, so now you only have 5 megs left in your permgen. then you try to load wicket whose jars need more then 5 megs, so you get an out of permgen error. this is a gross simplification, but basically what happens. permgen is called perm(anent) so it is not cleaned up, once something is loaded it sticks. so really it has nothing to do with load, it has to do with the number of classes you try to load into that jvm. the more libs you use the more different classes are loaded, the more space you need. -igor On Feb 12, 2008 1:17 PM, Vincenzo Vitale <[EMAIL PROTECTED]> wrote: > Hi Igor, > > thanks for your fast answer (as usual)!!! > > So this also means that it's the high load on the bigger applications which > is causing that *only* the smallest (and less used) Wicket app has at the > moment the problem.

You got it. ('late binding' is probably the wrong synonym here, but it's
a
good metaphor anyway.
At least for me ;-) Instead of showing only the number of total albums
which
existed
at creation time of your component, by using this extra indirection step
you
get
your method evaluated each time the component is rendered (which can
happen
quite later
when your album collection changes, e.g. when you use this label on a
page
where you
manage your stuff).

Re: OutOfMemoryError on FilePageSerializingThread
Hi Igor, thanks for your fast answer (as usual)!!! So this also means that it's the high load on the bigger applications which is causing that *only* the smallest (and less used) Wicket app has at the moment the problem. Do you agree? We will try to monitor the usage by all the application deployed. I don't know if Jboss has already something with this value available (ideally an Mbean). Ciao, V.

You got it. ('late binding' is probably the wrong synonym here, but it's a
good metaphor anyway.
At least for me ;-) Instead of showing only the number of total albums which
existed
at creation time of your component, by using this extra indirection step you
get
your method evaluated each time the component is rendered (which can happen
quite later
when your album collection changes, e.g. when you use this label on a page
where you
manage your stuff).

RE: StringResourceModel - how to pass method call instead of bean
Well, the reason why was I didn't know that call existed ;-) Of course I
looked at the JavaDoc, but the examples there didn't show this scenario.
Thanks a LOT for your reply - this addresses exactly what I'm looking
for :-)
One more question - what do you refer to with 'late binding' - I assume
the value would be computed 'late' in the process? Please elaborate or
send me a pointer.
Michael
**
Why dont you simple use MessageFormat's parameter substitution as
desribed
in the JavaDoc, i.e.
.. new StringResourceModel("label.getTotalAlbums",this,null,new
Object[] {
getTotalAlbums() });
with
label.getTotalAlbums=All Albums: ${0}
Alternatively, I you need late binding put
new AbstractReadOnlyModel() {
public Object getObject() { return getTotalAlbums(); }
}
in the object array (instead of getTotalAlbums() directly)

yes, you can subclass a page and put the resource next to it. another alternative is to put the package into the same package as the original page. yet another alternative is to add those keys to your myapplicaiton.properties -igor On Feb 12, 2008 7:49 AM, Wang, Yuesong <[EMAIL PROTECTED]> wrote: > Maybe you can extend the page, or duplicate the external package in your > own code base, and put your localized properties file there?

Re: panel doesn't see page which it create?
add(new CheckBox("openLocationPanelLink") {
oncomponenttag(tag) {

that way your code will execute during render time at which markupid
is available.

Subject: StringResourceModel - how to pass method call instead of bean
I actually have a follow up question regarding StringResourceModel - the
tutorial shows this example, which makes sense:
add(new Label("greetings", new StringResourceModel("label.greetings",
this, new Model(user;
Now, if I want to call a method that returns a String instead, like
so...
add(new Label("greetings", new StringResourceModel("label.allAlbums",
this, new Model(getTotalAlbums(;
^^^
...with my properties file having this entry:
label.getTotalAlbums = All Albums: ${someReference}
Obviously, this doesn't work, since the new Model(xxx) call expects a
bean to be passed in. How can I do this with a simple method call? And
what would my someReference var be?
Hope this makes sense - I just want to avoid passing in/creating a bean.

Re: OutOfMemoryError on FilePageSerializingThread
this memory space is shared by all libs in the vm. so maybe your ears are taking up a ton of space and only a small amount is left to the wicket app...its just not the right way to look at the problem. this is not heap space which is allocated for runtime stuff, this is the space used by VM to hold bytecode for classes...it doesnt matter how small the app is or what load it is under... -igor On Feb 12, 2008 3:27 AM, Vincenzo Vitale <[EMAIL PROTECTED]> wrote: > Hi Johan, > > we proposed the increased memory solution to our IT department but the > answer was: > > " Why this problem is occurring only with the small application using > Wicket?". > > We have three ears deployed on the same Jboss instance.

Re: Hook into RequestCycle ?
The auth-roles project is basically an example, so the fact that you copied it, is a good thing (tm). Even though it is sufficient for a lot of projects, if you need anything beyond the current capabilities, then rolling your own is the way to go. Or use Swarm/Wasp from Wicket Stuff.

There is not way to provide a automatic sign in since this can be only be done via signIn(username,password) on AuthenticatedWebSession. It would be possible if AWS.isSignedIn() wouldn't be final, so one could dynamically check for the cookie (and not only for a previous occured manual authentication). The solution I've chosen right now is to set an own UnauthorizedComponentInstantiationListener in my AuthenticatedWebApplication which copies over 90% of the existing functionality. This is certainly not an ideal solution. In general, I'm a fan of final methods, too in order to restrict unwanted extension points, but for AWS.isSignedIn() it would be probably a good idea to allow overriding or at least to provide and additional hook to relax the restriction to work with manual authentication via AWS.signIn() only.

Switching locales with the same link
Hi,
I've just started with Wicket, and I'm struggling a bit with the
documentation. Google hasn't helped either to provide an answer.
What I'm after is to have a 'switch locale' link in a different
language. Suppose you have an English (default) and a Dutch version, you
would have 'Nederlandse versie' on the English page, and 'English
version' on the Dutch page.
The page is a single HTML page, with the different text labels in
properties files. The locale code that you'd want to switch to ('en' for
English, 'nl' for Dutch) is stored in the properties files as well.
Now, I don't want to make two HTML pages, because this one is going to
be used for the navigation structure, and having two pages is
undesirable because of the maintenance aspect.
I did manage to switch languages, but only by hard-coding the locales in
the Java file, checking what the current locale is, and switching to the
other one. Whilst it works, it's a clumsy solution. I've considered
panels and separate HTML files for the link, but that too looks
needlessly complex.
So, is it possible to make a link that takes the language code from the
properties file as a parameter, and does something along the lines of
getSession().setLocale(new Locale(lc)), where lc is the language code
from the link?
Thanks,
- Peter

Re: panel doesn't see page which it create?
Hi Adr,
The markupid of any component is only assigned when the containing
component is actually added into the page.
The way around this is that the AttributeModifier (and most other
behaviours I believe) class actually renders the "onclick" event during
the onComponentTag(..) method of the panel being rendered at which point
the markup id's are set.
You can just wrap the javascript in a model that will generate the
correct text string when getObject() is called.
My helper class for this case takes in a string and replaces a
placeholder with the desired markupid when the getObject() method of
IModel is called.
e.g. panel.add (new AttributeModifier ("onClick", new
MarkupIDInStringModel ("var panel=document.getElementById('" +
MarkupIDInStringModel.MARKUP_ID_PLACEHOLDER +
"');panel.style.display=this.checked?'block':'none';", addLocationPanel));
so when the onComponentTag method is called the model inserts
addLocationPanel.getMarkupID() into the placeholder value.
Regards,
Mike

Re: Harnessing Data From Components
Data in wicket components is wrapped in models. You can ask a component for its model: getModel() and then ask the model for its data: getObject(). Or you can use the shortcut getModelObject() on a component. Setting data is done in a similar way.

panel doesn't see page which it create?
Hello,
I have Panel on which in constructor I put nested Panel:
public class RegisterUserPanel extends Panel {
public RegisterUserPanel(String id) {
...
final Panel addLocationPanel = new AddLocationPanel("addLocationPanel");
addLocationPanel.add(new SimpleAttributeModifier("style", "display:none;"));
add(addLocationPanel);
add(new CheckBox("openLocationPanelLink").add(new
SimpleAttributeModifier("onclick", "var
panel=document.getElementById('" + addLocationPanel.getMarkupId() +
"');panel.style.display=this.checked?'block':'none';")));
..
}
It's as you see another panel, and the exception is thrown:
WicketMessage: This component is not (yet) coupled to a page. It has
to be able to find the page it is supposed to operate in before you
can call this method (Component#getMarkupId)
It means for me that addLocationPanel.getMarkupId() is not setup yet
(it could be quite obvious, because it's constructor and I haven't
send any info about page to it, and probably it's send after creating
instance). But what can i do in such situation? What is best pattern?

Re: wicket-security, everybodyprincipal and only securepages
Hey William,
How is the ldap integration comming along?
Like i said then, i don't have a solution ready for how you would do
such a thing, and frankly it doesn't bother me enough if sometimes i
have to implement ISecurePage myself.
But i welcome a contribution that could do it :)

problem using DataGridView
Hi There,
I'm trying to add a DataGridView to my page with custom columns, here is what
I've done:
DataGridView table = new DataGridView("rows", columns, new
ReportDataProvider(values));
with this html:
cell content goes here
this is ReportDataProvider:
public class ReportDataProvider implements IDataProvider
{
Vector data;
public ReportDataProvider(Vector data)
{
this.data = new Vector(data);
}
public IModel model(Object object)
{
return new ReportModel((SystemReportBean) object);
}
public int size()
{
return data.size();
}
public Iterator iterator(int first, int count)
{
List vec = data.subList(first,first+count);
return vec.iterator();
}
}
and ReportModel is a plain object with getter setter methods
but I get this exception every time I try to view the page I get this exception:
WicketMessage: Error attaching this container for rendering: [MarkupContainer
[Component id = cells, page = com.laser.monitoring.gui.ReportResultPage, path =
41:rows:1:cells.AbstractDataGridView$2, isVisible = true, isVersioned = false]]

Re: Form/Enter Key Problem
My workaround was this. The idea is to add a submit behavior to the text
field, and it fires that only when user hits enter.
This code is inside the form's constructor.
searchCriteria = new TextField("searchCriteria", new Model(""));
searchCriteria.add(new AjaxFormSubmitBehavior(this, "onkeypress") {
protected void onSubmit(AjaxRequestTarget target) {
//submit code
}
protected CharSequence getEventHandler() {
CharSequence handler = super.getEventHandler();
String check = "javascript: if (event.keyCode == 13) { ";
String endCheck = " return false; }";
return StringUtils.join(new Object[] { check, handler, endCheck });
}
});
What do you think?

RE: wicket-security, everybodyprincipal and only securepages
I still think that a more elegant and non-obtrusive solution would be
mountSecurePage(MySecureWebPage.class)
discussed previously in:
http://www.mail-archive.com/users@wicket.apache.org/msg09129.html
That way you could have one basepage because they would not have to extend
SecureWebPage

If i add an extra method isUserAuthenticated to my

everything in the WaspSession class.
I need to know if a user is logged in before i force the session to bind.
Thnx Johan.

Re: OutOfMemoryError on FilePageSerializingThread
Hi Johan, we proposed the increased memory solution to our IT department but the answer was: " Why this problem is occurring only with the small application using Wicket?". We have three ears deployed on the same Jboss instance. One is using Spring MVC, one CXF and the admin module is using Wicket. Actually the admin module is used by only one person when the other ones have a high load. We are using wicket.1.3.0-beta2 and the wicketstuff-dojo (1.3.0-dojo). We actually cannot reproduce the problem in an easy way and IT is not sure if it's caused by how we are using Wicket. Have you any glue or suggestions on that? Thanks, Vincenzo.

I think you should be able to get into the same session by including a
JSESSIONID
parameter in your jsp url, like "user/include.jsp;jsessionid="
Another possibility would be to have the browser call the jsp url,
maybe with an iframe
or something like that...

Re: Hook into RequestCycle ?
Take a look at wicket-auth-roles. This provides the usual security stuff,
and you can easily also check for a set cookie. Just implement your own
authorisation scheme.

Application.newRequestCycle() ?
Quite easily found by searching references to RequestCycle.

Re: Including dynamic JSP content in Wicket page
Can you attach with debugger to see what is in the Session actually?
Because if you set the User object via Wicket's Session then it prepends
a prefix to the key of all objects in the session. See
o.a.w.protocol.http.WebApplication.getSessionAttributePrefix(WebRequest)

Including dynamic JSP content in Wicket page
I'm trying to include JSP content in my Wicket page. The JSP content depends
on some data that is stored in the HttpSession - in this case the data is a
user object.
I have tried to use the Wicket Include like this:
add(new Include("includedJSP", "user/include.jsp"));
Using the this form always returns a null user object because the underlying
code in the Include class opens a new URL connection that has a different
session, so my user object is not available.
Can anyone suggest a way of getting around this?
Thanks,
Declan
JSP file:
<[EMAIL PROTECTED] import="sg.com.mps.demo.model.persistence.User" %>
<%
System.out.println("Session ID: " + session.getId()); // every call
returns a different session ID
User user = reqHandler.getLoggedInUser(session); // always returns null
System.out.println(null==user?"null":user.toString());
if (user == null) {
return;
}
%>
Logged in as: <%= user.getLoginName() %>
Logout
HTML:
included JSP goes here

Re: wicket-security, everybodyprincipal and only securepages
If i add an extra method isUserAuthenticated to my
WaspAuthorizationStrategy, then yeah i probably could let wasp handle
everything in the WaspSession class.
I need to know if a user is logged in before i force the session to bind.
Thnx Johan.

Re: wicket-security, everybodyprincipal and only securepages
About stackoverflow, cant you do that code in attach() of the session?
(test ofcourse if you want to do it once)

I don't think this is true, consider the following class hierarchy
BasePage extends WebPage (has own markup file, probably containing
wicket:child tag)
MySecurePage extends BasePage implements ISecurePage (has no markup file)
Every other page either extends BasePage or MySecurePage
This way you only need to modify BasePage if you want to make some
layout changes to all your pages

Maybe i am missing the point but why would you have 2 versions of a
page one secure and the other not.
If you are trying to build a page that contains both secure an
insecure content, you have 2 options
-let your page extend BasePage (as designed above) and place all
content on it (both secure and insecure)
If you have a lot of content that needs to be secure (in effect
wicket components) you might want to consider grouping it together in
a Panel.
I'll asume you have a Panel with all you secure content but the same
goes for any type or number of components
Add a ComponentSecurityCheck (or any check you like) to the component
(using SecureComponentHelper)
Then add permissions for the secure part to your policy file
grant org.MyPrincipal "regular user"
{
permission ${ComponentPermission} "org.MyPage:mySecureContent",
"inherit, render";
//the part after the : represents the wicket path to the component
as seen from the page, all components are separated by : so you might
get something like org.MyPage:mypanel:mytextfield
}
Because the page itself is not secure it is always rendered, and
because a ComponentSecurityCheck typically does not check for
authentication a guest will always see the page without the secure
content, a logged in user however (with the correct principals) always
sees all content.
-let your page extend MySecurePage (as designed above), like the
previous option you add a check to content you want to secure.
you add the same permission to your policy file and in addition you
add the page to the general grant block
grant
{
permission ${ComponentPermission} "org.MyPage", "render"; //do not
use inherit here
}
This way the user is required to log in but all user will be able to
see the nonsecure content of the page, only users with sufficient
permissions will see the secure content

If you want a site with a public and restricted area, all you have to
do is let the public pages extend BasePage and the restricted pages
MySecurePage as shown above. All you pages will share the same
(single) markup.

Yep i get where you are going but i would not do it by automatically
signing in people as guests.

Yeah i found those lines. The thing is i added those lines to support
clustering. And the only way you are going to get there is if your
LoginContext specifies multiple logins are allowed, which is probably
what you are doing after reading your story :)
I'll see if i can come up with an elegant solution for this.
In the mean time, i think i have given you a couple of ideas on how to
proceed without automatically logging someone in.
Let me know if you have any more questions.

Re: Multiple panels and back button
Hi Igor, The problem with the back button is that if i dont setResponsePage(), after updating (or removing) a record from the list and pressing the back button, the system displays the exact previous data entry form with the old values of each record(!). If i had made, lets say 10 updates, the system will display all previous 10 forms. I noticed that the url parameters have a format like "?wicket:interface=:1:8:::" where the second number changes every time i save (or remove) a record. If i press the back button then the second count decrements by 1 and the previous form is displayed with obsolete of course data. What the user expects by pressing the back button is to return to the menu (or whichever the caller page was) and not to the previous data entry form which is quite dangerous. This somehow is achieved by setting setResponsePage() inside the onClick code. I am quite sure that it is not wicket's "problem" and maybe i have to setup the whole page in a different way to achieve the behavior i want but i cant figure it out.

Re: wicket-security, everybodyprincipal and only securepages
hi maurice,
thanks for your answers. The reason why I want to avoid to have two
basepages (one implementing ISecurePage) is that if I wanted to change
something, such as markup, in the basepage I'd have to change it at two
places. Even worse if I extend my extended basepages further, there would
always have to be one version that does implement ISecurePage and one that
doesn't. So I'd end up adding two pages with the same markup everytime when
I'd like to add a page.
As you might have noticed my app can't be compared to an app such as an
online-banking-app where you have one loginpage and the rest is behind the
big door on secure pages. In my application there are some pages that are
for registered members only but which do (or at least should) extend the
same basepage as a regular page. So I thought I'll sign any visitor in by
default, without any roles sothat they're able to access and render any
component inside of
grant { ... }
and then if a user logs in with username and password, I'll give 'em a
different role such as user and let them access and render anything inside
grant user { ... }
makes sense?
ah yes, creating a stackoverflow: just call the session.login(LoginContext)
method inside the session's constructor (or inside your application's
newSession method) and let it return a subject, then line 84 of the
logincontainer class calls Session.get() that in turn calls findAndCreate
that in turn calls the session's constructor that in turn calls
Session.get() ... and so on

ok, so the memento's are not incremental? Then only one memento should be enough to restore the order back to the state the user created. That sound good.

Hook into RequestCycle ?
Hi,
what is the best place to hook into the request cycle
before a page gets processed ? I looked through
http://cwiki.apache.org/WICKET/lifecycle-of-a-wicket-application.html but
the
information there seems to be a bit outdated ("the Session returned by the
Application
is asked to create a RequestCycle object using the Session's request cycle
factory",
but there's nothing like a request cycle factory which can be obtained from
a Session in 1.3)
Is there a more accurate documentation of a request's lifecycle somewhere
else ?
My use case is as follows: Before any page is processed I want to look up in
the Session,
whether a user is authenticated. If not, it is checked wheter a certain hash
stored in a Cookie
(if any) is stored in the DB and the associated user then is put into the
session, providing some sort
of 'keep me logged in' functionality. (The 'remember me' feature of the
SignInPanel is not enough for
me, since I want a transparent login without moving over the login page). Of
course, if there is already
support for this kind of feature out of the box somewhere, I would be happy
for getting a pointer, too.
thanx ...
... roland
