Re: What exactly is IWrapModel used for?
Hi Sven Thanks for your explanations. I do now see why there's this wrapper. However, the StringResourceModel appears to break its contract since every LoadableDetachableModel should be loaded using its load() method which cannot be used here! I can fix this by just using delegation instead of subclassing but in my opinion this is just plain wrong that implementors need to know which classes may be overriden and which do not. We have several subclasses of StringResourceModel doing some special stuff like reducing all unresolved properties to the empty string or even returning a completely different String if not all expressions were resolved correctly (for cases where the model object itself is null and thus no properties can be resolved at all) etc... This should either be fixed so that load() can be overriden and works as expected or then it should be made final with a notice why it's not supposed to be overridden. Shall I open a JIRA for that? Regards Matt On 06.08.2012 21:41, Sven Meier wrote: Hi Matt, I don't know about your example but the following makes perfect sense: new Label(id, new StringResourceModel(foo)); This way the message is resolved relative to the label. If the StringResourceModel's constructor is given a component argument, it doesn't make sense to pass it to other components as model, since it will be reassigned anyway. AFAIK this variant is meant to be used ad-hoc without passing it to a component. Maybe it would be better for your OurStringResourceModel *not* to extend StringResourceModel?

Hi,
The LogoutPage in the application I work on is quite simple:
- first we invalidate the session with session.invalidateNow() like you do
- second we throw a RestartResponseAtInterceptPageException with the Page we
want the user to go to after the logout process (actually we use it with the
class of the Page we want, but you can pass it an instance of a Page).
Hope this will help.

Hi
I'm trying to implement a simple logout mechanism with the need of
complete session termination.
For this I created a LogoutPage and mounted it using
mountPage(/logout, LogoutPage.class);
Now this page contains multiple components and a link to change
langugage etc, therefore it is stateful.
But when I perform a session.invalidate(Now)() in the page's
constructor, the user gets redirected to /logout?0 with a new session
ID. Probably though the page was stored in the previous session so it
doesn't exist with the new one, then he gets redirected back to
/logout, back to /logout?0 and so on.
What do I have to do to implement this simple logout page?
Thanks

Wicket 1.5 vs 1.4: StringResourcesModel with properties in the key
Hi
I'm currently migrating a project from 1.4 and am encountering a Problem
with StringResourcesModel:
I've got one defined as:
new StringResourceModel(details.disabled.${disabled}, this.model)
isDisabled returns a boolean naturally.
In 1.4 this worked as expected and the resource keys
details.disabled.true or details.disabled.false were taken.
Unfortunately, there's a default IConverter in place for boolean values
since those usually needs to be displayed as yes and no (or alike in
the other languages).
In Wicket 1.5, the StringResourceModel now does some heavier processing
on the key, thus the boolean value is converted first using the
registered converter and then inserted into the resource key; resulting
in keys like details.disabled.yes or details.disabled.ja etc which
are even language dependent!
Is there a possibility to revert to the previous behaviour except for
overriding the StringResourceModel (and a lot of other classes) and
except for removing the global boolean converter? The latter isn't
doable as it would be nearly impossible to find out where those booleans
are used throughout the pretty huge application
Thanks

Re: Difference b/w SetoutputMarkupId(true) and SetOutputMarkupHolderTag(true?)
Hi setOutputMarkupId sets the id attribute of the HTML tag. This generally must be set if the tag shall be updated by AJAX setOutputMarkupPlaceholderTag has the effect that a *hidden* component is still added to the HTML tree but - hidden. This is used, if the component is initially not visible (isVisible() == false) and would normally not leave a trace in the generated HTML file, thus it cannot be set visible by AJAX since it doesn't have a 'handle' to it. So it generally must be set to true if the component is to be updated by AJAX but is NOT initially visible.

Re: How to clear PageMap in Wicket 1.5?
Hi Martin
Sorry for the delay, I was busy with other things recently.
Of course you're right, that clearing all pages, including the NextPage
isn't a smart thing and I don't wanna do that anyway.
But what I need is away to redirect to a new (non-bookmarkable!)
NextPage while clearing all other stored page instances.
I'll try to illustrate a flow; the user starts on the homepage
HomePage. All pages are stateful:
HomePage click on a link AnotherPage click on the special Link we're
talking about NextPage.
Now, when the user is on the NextPage of course all links on THAT page
do have to work as expected. But all previous page instances (of
HomePage and AnotherPage) must be cleared from the page store, so that
if the user clicks BACK in his browser (and would go back to
AnotherPage), a PageExpiredException must be thrown.
I can achieve that with Session.replaceSession() BEFORE calling
setResponsePage(new NextPage()) - but this method has additional
semantics (change the session ID) which I may not want to have.
That's why I came to
getSessionStore().invalidate(RequestCycle.get().getRequest());
which *appears* to do what I want but due to the lack of knowledge of
the session/pagestore internals I cannot say if it's correct or
sufficient to do that...
So the important bit is, that when calling a usable Session.clear(),
the current page shall not be stored in the session/pagestore anymore...
Thanks

The method you propose results in the next page shown as expected and going

The problem seems to be in the order of events:

2) Then the user is redirected to a new page with setResponsePage(new
NextPage())
3) Then the request ends and if cleaning up is performed at this stage, it
doesn't know to keep the NextPage and its links but clean everything else
No 3 could be addressed in wicket 1.4 using the internal untouch method to
tell wicket NOT to store that page anymore.
One question: what should happen when the user is redirected to
NextPage (because of setResponsePage(new NextPage())) and
the user clicks on a Link ?
Wicket will try to find the page to execute Link#onClick() but since
the page is not stored Wicket will throw PageExpiredException.
The same will happen if the user refreshes the page with F5.
How do you handle that case ?
Session.clear() removes all pages stored so far. If you use
setResponsePage(anInstance) then a new page will be stored afterwards.
If you really want to clear all pages even the NextPage instance then
you can do:
class MyRequestCycle extends RequestCycle {
private boolean fullClean;
public void fullClean() {
fullClean = true;
}
@Override
public void detach() {
super.detach();
if (fullClean) {
fullClean = false;
Session.get().clean();
}
}
}
What appears to work is create a public method in my session which calls:
getSessionStore().invalidate(RequestCycle.get().getRequest());
This seems to work (and is part of what replaceSession() does) but I don't
know the internals of the new PageManager et al so I'm not sure if this is
already enough and correct?

Re: Wicket requests
Hi Yes, wicket usually handles such things internally, saving you the overhead of multiple redirects. However, if you need to modify cookie data and you must rely on getting these infos back in the following request, you need to force a round trip to the client using setRedirect(true). HOWEVER you might well run into trouble with that too, since the default strategy of wicket is to render the next page while still in the context of the previous one, then actually send the redirect and if the next request comes in, it just streams the cached page back. You can change the strategy used somewhere not to use those buffers, but this might have even other effects.. So such a situation is very tricky and you need to be well aware of that pre-rendering and buffering of the next page... Matt On 2011-04-21 09:10, Gabriel Teris wrote: Hi, I am quite new to wicket, and I am trying to better understand how the requests are handled. My problem is this: I have a landing page in my application, where I check if the session is a correct one(I have a parameter called sessionId which dictates the user's session). If the session is null, I create a cookie with the given parameter value, and if the session has an unexpected id I invalidate it and create a new cookie (as above). Cookies are activated between requests, but as I see in Firebug there is only one request while displaying 3 pages! Should I use setRedirect(true) on the page to force redirects? For page rendering I use the setResponse(Page.class) method, not page instantiation. I also tried looking for detailed navigation in Wicket in Action and Pro Wicket books, but I didn't find anything detailed. smime.p7s Description: S/MIME Cryptographic Signature

Hi Martijn Yes I know that, but as I stated, it's still possible to reload that page and perform actions on it (they are *all* stateful pages) - I must know how I can suppress that.

Re: How to remove all previous pages from pagemap
I now found one way to clear all previous pages. I guess the reason is the REDIRECT_TO_BUFFER strategy (or however it's called) which both processes a button's onClick() event AND the next page's full initialization+rendering in one request. Thus the previous page (where the button was) is marked as 'touched' in the Session as well - no matter when I clear all the pagemaps, the previous page will just be re-added at the end of the request. My current solution which solves this problem (although ugly) is the following code in the onClick: // Make sure this page does NOT get stored at the end of the request getSession().untouch(getPage()); // Clear all previous stored pages getSession().clear(); // display the confirmation page setResponsePage(new ConfirmationPage(...)); I still hope there's a better solution but this works for now Does anyone know if there's the possibility to override the REDIRECT_TO_BUFFER strategy for a certain redirect? This would also solve this problem as then the Session.clear() would be executed in the next request after the onClick() thanks Matt On 2011-01-25 18:14, Matthias Keller wrote: Hi List We've got the following scenario: After a user hopped through a wizard, he'll reach a confirmation page in our workflow.

However, that would make the confirmation page bookmarkable, something you probably don't want :) Ugly use case sometimes requires ugly code :-).. I don't think this is ugly, it performs each step you need explicitly. The use case to remove pages from the page map is not that common, so the story for doing that is not as nice. Perhaps something like a @DontStoreInPageMap annotation could be used. This would put the page in the session, ensuring you still have the stateful programming model and are able to work with the page as if it were a normal wicket page. But the page would not be put in the pagestore. I guess this would still work across clusters to support failover: the current page would still be stored in the session, making it available on all buddy nodes. Martijn Hi Marijn Thanks for your reply Well, if the code's ugly or not is one side - the time required to get to that point is the other side - I spent hours trying to figure out why Session.clear() apparently does not work. To understand that, a lot of insight into Request Cycles, PageMaps and Render Strategies is necessary. I'd very much welcome a hook to alter the render strategy just for the next page. setRedirect(true) does not change the strategy and is the default in the (default) REDIRECT_TO_BUFFER strategy: In this case the next page is rendered and stored, then the user is redirected to a new url (to solve the Reload-after-POST problem) - the new url only serves the previously cached HTML code and does not call any hooks on the page itself (because it doesn't even know about it, I guess). So what I'd need would be a kind of setRedirect() which switches to REDIRECT_TO_RENDER. Matt smime.p7s Description: S/MIME Cryptographic Signature

wicket:message and property resolving
Hi
I just disovered by chance that it's possible to use property
expressions in normal wicket:message key=.../ elements which then
get resolved against the next model found in the hierarchy.
Unfortunately it seems to work a bit different to other automatic
resolving like in new Label(property).
Example:
I've got a page with a WebMarkupContainer containing both a normal
(wicket) label and a wicket:message in the HTML.
The page model's object has a method say String getSomething()
Java:
WebMarkupContainer c = new WebMarkupContainer(container);
add(c);
c.add(new Label(something));
HTML:
div wicket:id=container
span wicket:id=something/
wicket:message key=myKey/
/div
Properties:
myKey = Here it is: ${something}
The Label works as expected and displays the return value of the
getSomething() call.
The message fails with a big exception since it tries to get the model
from the WebMarkupContainer and complains, that there's no
getContainer() method...
Shouldn't this work the same way as with labels, by 'finding' the nex
model available?
The quick solution is to give the WebMarkupContainer also the default
model of the page which works but is not very nice...?
Is this a bug? Then I'll file a JIRA
Thanks

How to tackle field labels when using CompoundPropertyModels?
Hi This is an issue I frequently run into and I haven't found a good solution yet: I've got a Form using a CompoundPropertyModel and having lots of fields. The easy way to do these fields is: form.add(new RequiredTextFieldString(name)); The model object has a getter and setter for name, so all works well. Unfortunately, when the user doesn't enter a valid value, the Required error message shows up saying something like Field 'name' is required. I could have a resource key name in my translations but this has the limitation, that all name fields in my whole app are translated the same way. Maybe one name is a human name, the other one is a machine name which have different translations... Is there an easy way to tackle this problem? For example have a prefix prepended to the field name or something else? One thing I want to avoid is to set an explicit label model for every field and if possible I'm hoping to avoid having to create different TextField subclasses for all my pages just prepending that string How do you do this for large applications?

Re: component not visible exception
One other thing to check is, do you have a custom isVisible() override in the container or do you explicitly set it to visible/invisible using setVisible()?

In that case consider to use session.invalidateNow() to immediately destroy the (old) session and then create a new one.

AutoCompleteTextField uses wrong encoding?
Hi I'm using an autocompletefield and it works fine so far. Except that when entering special characters, they don't get encoded correctly. The query String is correct and sends the special character in encoded UTF-8: GET http://localhost:9080/.../...q=%C3%B6random=... %C3%B6 is UTF8 for ö But in: org.apache.wicket.extensions.ajax.markup.html.autocomplete.AbstractAutoCompleteBehavior.respond(AjaxRequestTarget) The following line final String val = requestCycle.getRequest().getParameter(q); returns an incorrect string: ö which would be the %C3%B6 in ISO-8859-1 (which happens to be my platform encoding)... Thus the input parameter to my getChoices() call contains strange characters in this case... It appears that the request isn't read out as UTF-8 somehow..

Re: How to use DateTimeField with java.sql.Timestamp
DateTimeField internally uses a DateTextField which is a normal
TextField initialized as type java.util.Date
You could create a class:
public class TimestampField extends DateTimeField {
protected DateTextField newDateTextField(String id, PropertyModel
dateFieldModel)
{
return new DateTextField(id, dateFieldModel, new
StyleTimestampConverter(false));
}
}
This allows you to create your own converter which results in a
Timestamp object.
you could for example just extend StyleDateConverter to take advantage
of its implementation and in your override of convertToObject() you
could convert the super.convertToObject() Date to Timestamp

AutocompleteTextField in wicket 1.3.6 ?
Hi I just tried to add a AutocompleteTextField to a 1.3.6 application but it doesn't seem to work. I copied the exact example from http://www.wicket-library.com/wicket-examples/ajax/autocomplete and removed the generics for 1.3.6 Yet still no matter if I enter anything or not, no autocomplete shows up and the ajax debug stays completely empty... Is there anything else to try or is there something more required to get it to work in 1.3.6 as opposed to 1.4.x ? Thanks a lot Matt -- matthias.kel...@ergon.ch +41 44 268 83 98 Ergon Informatik AG, Kleinstrasse 15, CH-8008 Zürich http://www.ergon.ch __ e r g o nsmart people - smart software smime.p7s Description: S/MIME Cryptographic Signature
Re: EntityModel
Injection is easy
Just call:
InjectorHolder.getInjector().inject(this);
in your EntityModel constructor.
That's it.
While developing if you hot-redeploy often, you might also want to do a
check in load() like:
if (this.whateverService == null)
InjectorHolder.getInjector().inject(this);

Re: Force page reload/re-render
Hi Pieter
Due to the Java-Nature of Wicket, things done in the constructor are
only executed once for this instance. Since F5 only re-renders the
instance, the expression setVisible(whatever()) is only executed once.
The most dynamic implementation would be to override isVisible() for
every component that changes its visibility dynamically or if that would
lead to lots of code duplication, you could write a behaviour doing
exactly that and add it to every component (or container) as needed.
isVisible() is evaluated during each and every rendering phase, meaning
upon every F5 reload as well.
This is the way we do it for dynamic content.

It seems that there is no way to force the page to re-render using getPage()?

Even if condition getSomeCondition() change, and you re-render MyPanel, or

Check(box) loses checked state after error
Hi I'm using a CheckGroup together with a few Check in a repeater because the number of boxes displayed is dynamic. This works fine and the data gets stored in the model correctly when submitting. However, if another form component fails in the validation, all checkboxes are getting unchecked. It seems the uuid increased after the error and does not match the submitted data anymore. In Check.onComponentTag(), the group.hasRawInput() returns true and contains for example check60, check61 but the uuid variable is much higher then, vor example 120, resulting in no checkbox being checked.

If you have a repeater the redraw event instantiates NEW checkboxes..
so ofcourse you lose the staete.
I have built a reusemanager that copies the old state. Usage sould be
quite straight forward, ask if you need help.
Here is a simple example of usage:
add(reuseManager.rememberOrReuse(rowIndex, custom_id, hoursField));

public class FormComponentReuseManager implements Serializable {
private final MapObject, MapString, Component idMapRow = new

* @param newComponent

public T extends Component T rememberOrReuse(Object rowId, String
componentId, T newComponent) {
MapString, Component rowMap = createOrReuse(rowId);
@SuppressWarnings(unchecked)
T existingComponent = (T) rowMap.get(componentId);
if (newComponent instanceof FormComponent) {
// Never reuse the component itself, just reuse the
rowMap.put(componentId, newComponent);
if (existingComponent != null) {
MarkupUtils.fakeRawInput((FormComponent?)newComponent,
(FormComponent?)existingComponent);
// Transfer also the error messages
for (FeedbackMessage feedbackMessage :
TakpSession.get().getFeedbackMessages().messages(new
ComponentFeedbackMessageFilter(existingComponent))) {
MarkupUtils.replaceReporter(feedbackMessage,
(FormComponent?) newComponent);
}
}
return newComponent;
}
// else
if (existingComponent == null) {
rowMap.put(componentId, newComponent);
return newComponent;
}
// else
return existingComponent;
}
/**
* @param rowId
* @return MapString, FormComponent
*/
private MapString, Component createOrReuse(Object rowId) {
MapString, Component rowMap = idMapRow.get(rowId);
if ((rowMap == null) (rowId instanceof AbstractDTO)
(((AbstractDTO) rowId).getId() != null)) {
rowId = ((AbstractDTO) rowId).getId();
rowMap = idMapRow.get(rowId);
}
if (rowMap == null) {
rowMap = new HashMapString, Component();
idMapRow.put(rowId, rowMap);
}
return rowMap;
}
/**
*
*/
public void clear() {
idMapRow.clear();
}
/**

It supports both MessageFormat style and model-style replacements.

wicket:message key=test /
In Struts something like
mymessage = foo {0}

bean:message key=mymessage arg0=bar/
was possible, which produced foo bar
Is there already a way to do this?
And if not, do you think it is worth being implemented?

Re: How can we display by example the format to be used to input Date in DateTextField ?
Hi Charles
About Question 1: The validation message seems to have its origin in
FormComponent#convertInput():
It will try either IConverter.date class simple name or
IConverter and the used pattern will be available as the variable
format (or ${format} as used in the string resources).
About Question 2: You'll have to subclass the DateTextField and override
getConverter().
You could then just check if the returned super.getConverter() is of
type DateConverter and if yes, call the setLenient() method on it.

used ?
Question 2 . Can we define the format to be used (in the case of a
date) as setLenient() to verify if the date encoded is correct unlike
as the following date 20090230 ?

Re: Is it the best way to code a Link depending on a condition
Hi
As I said in my previous mail, just initialize the link once using the
upper variant.
Use an if before to create the requestFormModel, in case 2, the
requestFormModel can be null - as the onClick is never executed this
will not matter.
Have something like:
final Model requestFormModel;
if (case1)
requestFormModel = new MyModel(...);
else
requestFormModel = null;
// Creating the one and only Link instance.
link = new Link(linkRequest) {
public void onClick() {
setResponsePage(new RequestPage(requestFormModel));
}
}
item.add(link);
if (case1) {
link.add(whatever);
...
} else {
link.add(whatever for case 2);
link.setEnabled(false);
}

Re: Is it the best way to code a Link depending on a condition
Hi
Yes there'll always be some repetition. Depending on your logic you
might also stuff the first block in the onClick event to generate the
model if it's not used anywhere else. That could eliminate the first block.
The problem about reusable components in wicket is that probably you
might end up with some problems when using the same component instance
on two pages unless you re-instantiate your Commons class in every call
which might in turn produce a lot of overhead if you only need a few of
those labels and stuff.
What you could also du is writing a kind of factory method in a base
page class (I always have a BasePage class all my pages extend from with
some common functionality). There you could have a method like
protected Label getIdLabel(String value) { return new Label(id, value); }
Matt
cmoulliard wrote:
Mattias,
OK about what you propose but we repeat the test a second time so the code
still remains very verbose.
Thanks for the suggestion.
I think that this is a general remark that some users make about Wicket. It
is very difficult to reuse part of the code.
Here is another example :
I have a label called id which is used in different page. The way proposes
by Wicket to code it is
Page Request
item.add(new Label(id, String.valueOf(request.getId(;
Page Notification
item.add(new Label(id, String.valueOf(notification.getId(;
When we compare page request and page notification, we see that we repeat
the same code two times.
It could be interesting to set the value of the label in the page and to
declare it separately
e.g
public class Commons {
public static Label labelId = new Label(id);
...
}
Page Request
item.add( labelId.setValue( String.valueOf(request.getId()) );
Page Notification
item.add( labelId.setValue( String.valueOf(notification.getId()) );

How to redirect from a ModalWindow
Hi I've got a ModalWindow which lets the user select some choices. Now I need a button in that ModalWindow allowing the user to enter some new choices. I don't want that target to be another ModalWindow (as it's referenced from other places too), so I need to redirect the user to that new page if he wishes to add a new choice. Basically that works, using a Button or an AjaxButton both works, but since the ModalWindow is still open, I get the ugly browser warning about navigating away from the current page. What can I do to solve that? I tried an AjaxButton using window.close(target); setResponsePage(OtherPage.class); But that doesn't work. Any ideas?

Re: DropDownChoice with Java Enum
Hi
Close but not quite. getDisplayValue gets the catual ELEMENT of the list
- so objDispl is of type ProcessingStatusType already.
So in your case it would be something like:
public Object getDisplayValue(Object objDispl) {
return ((ProcessingStatusType) objDispl).getDescription();
}
public String getIdValue(Object obj, int index) {
return obj.toString();
// or if you prefer to have the value of your enum in the HTML code:
// return ((ProcessingStatusType) objDispl).getValue()
}
Which one of the getIdValue implementations you chose doesn't matter for
wicket, it just needs an ID for every entry which is unique.
In your case you could even return String.valueOf(index) as your
backing List of the Enums will not ever change while deployed.
Be careful though with using index, there are circumstances where no
useful index will be provided (always -1) - That happens when you
externally change the selected value of the DropDownChoice.
you could also just use or extend ChoiceRenderer which might already do
what you want...
For example
new ChoiceRenderer(description, value)

Re: How to redirect from a ModalWindow
Hi Peter You would be right as long as it wasn't for a ModalWindow. When having an open ModalWindow, wicket seems to register an unload javascript event which - when trying to navigate away from the page (be it by following a link, closing the window etc), displays a confirmation message which you have to accept. I need to avoid that message, but the only way to do that probably is by closing that window first so that the javascript event gets unloaded.

Re: Help on wizard solution...
Hi
Well, if you know of all the steps but there's only some small
difference (like you said, Step 6 might be D or F), you might also
consider a normal Wizard, but use the conditional step functionality.
That way you would add ALL pages, but hide those that are not relevant.
Hiding can also be done dynamically, for example if on the first step,
option A is selected, step 6 is visible, else not.
This is done in each step by overriding the evaluate() method. If it
returns true, the step is displayed, if false, not.

John Armstrong wrote:
I've done this in both DynamicWizards as well as regular wizards and

My rule of thumb is If you can gather all of the content together for
your wizard use a regular wizard (eg: non-dependent configuration
directives), if future wizard steps can change based on a specific
wizard step then use a DynamicWizard (eg: If you pick A on Step 5 then
Step 6 shows D, otherwise Step 6 shows F

Re: @SpringBean and IDataProvider
Hi Charles
@SpringBean only seems to work in some wicket base classes. In your own

What I do (maybe there's a better possibility) is to add this line to
that classes constructor to force injection:
InjectorHolder.getInjector().inject(this);
That way, all @SpringBean fields will be injected correctly.

Unfortunately, a column seems only sortable by a single property :-( Is there a possibility to sort a DataTable using the effectively displayed values instead of a fixed property?

Re: Choose one
Hi The implementation tries these keys: getId() + .nullValid nullValid So you could also have a global 'nullValid' entry somewhere in your resources which would be the default for ALL AbstractSingleSelectChoices such as DropDownChoice and RadioChoice Matt Gatos wrote: Is it possible to reuse existing translation - I like 'Choose one'?

StringResourceModel ignores Converters?
Hi I need to use a StringResourceModel to compile a string with multiple parameter substitutions. I have a lot of converters active which should take care of all these values and which do work when using for example a PropertyModel elsewhere. Unfortunately it seems the converters are completely ignored for StringResourceModels when doing the parameter substitution? I always get the data in its raw (.toString) form instead of the converted?! Is this a bug or a feature? Thanks Matt smime.p7s Description: S/MIME Cryptographic Signature
How to use Session.replaceSession() ??
Hi I'm writing our custom internal error handler which is supposed to terminate the current session and create a new one (in order to pass over the locale to the new session). I've stumbled upon the Session.replaceSession() method which, according to the javadoc, should just exactly do that. But when I call this method, nothing happens. The same session continues to be used and no new session is being created at all?! I've got it to work by using: Session newSession = getApplication().newSession(getRequest(), getResponse()); newSession.setLocale(getSession().getLocale()); getSession().invalidateNow(); Session.unset(); newSession.replaceSession(); But I think there must be something easier... ???!

Generic Navigation Panel
Hi I'm creating a new website with wicket which should have a normal navigation bar. I'd like to be able to detect whether a link points to the current page to give the surrounding div a special class. For example on page1: div class=activeLink a href=page1page1/a /div div a href=page2page2/a /div I thought about autolinking which does that automatically, except it adds very ugly spanem tags. I also don't want to change this globally just to have a nicer navigation autolinking going. In addition this would be tricky as I need the divs around the links, but with different CSS classes. I'm thinking about creating a panel (representing the div with the link) which then adds the link and which has to be created by giving the current page via the constructor in order for it to find out if the link represents the current page. But this seems to be very complicated so I think there must be a more elegant solution for that, as this requirement surely isn't anything new?!

Hi,
I am working on date fields and have problems with the validation. I
have referred to the link below which helped me.
http://www.nabble.com/Strict-4-digit-year-for-DateTextField--td18656889.
html
So I have subclassed the PatternDateConverter and have set the pattern
as,
dateFormat = ^(\\d{1,2})/(\\d{1,2})/(\\d{4})$;
I have 2 date fields, start_date and end_date. The start_date is a
required field and the end_date is not.
(...)
This works fine ie it does not allow entry of 03/03/09 or
03/03/-2009
BUT, the end_date becomes a required field. I have to enter the end_date
to click 'Save'. Else it complains that an invalid date has been
entered.
But my end_date is not a required field.
(...)
Possibly the simplest approach would be to use a regular expression that
allows an empty string like making the whole expression optional by
surrounding it with paranthesis and adding the optional operator '?'
after it. This allows the empty string OR a valid date but nothing else:
dateFormat = ^((\\d{1,2})/(\\d{1,2})/(\\d{4}))?$;

Problems using wicket with web.xml security
Hi We have a wicket application which should be completely secured by FORM authentication by the webserver. For that, we have the following in web.xml: security-constraint display-nameSecured pages/display-name web-resource-collection web-resource-nameAll Pages/web-resource-name url-pattern/*/url-pattern http-methodGET/http-method http-methodPOST/http-method /web-resource-collection auth-constraint role-namesomeRole/role-name /auth-constraint /security-constraint login-config auth-methodFORM/auth-method realm-nameSecure Everything/realm-name form-login-config form-login-page/login/form-login-page form-error-page/login/login-error.jsp/form-error-page /form-login-config /login-config security-role descriptionUser security role/description role-namesomeRole/role-name /security-role security-role descriptionUser security role/description role-namesomeOtherRole/role-name /security-role Unfortunately, it seems that every user having ANY role gets access to the wicket pages. For example a user with role someOtherRole will get access to the main page, as its url is for example: http://localhost:7001/app/?wicket:interface=:2 When he tries to access a mounted page though, he gets the Error 403--Forbidden as expected. But he should also get this error when trying to access the home page of the wicket app. I suspect it has something to do with the /* url-pattern not catching the /?wicket:interface=:2 ???

Re: Add a ui lock page over the page while waiting for response
Hi
Thanks for the input. I now used wicketstuff-jquery and wrote a custom
behaviour which adds the code to my form.
For later reference:
public class UIBlockerBehaviour extends JQueryBehavior {
private static final ResourceReference BLOCKUI_JS =
new CompressedResourceReference(UIBlockerBehaviour.class,
jquery.blockUI.js);
public void renderHead (IHeaderResponse response) {
super.renderHead(response);
response.renderJavascriptReference(BLOCKUI_JS);
}
protected void onBind () {
super.onBind();
getComponent().add(
new AttributeAppender(this.attributeName, new
ResourceModel(JQuery.blockUI.code), ;));
}
}
Where the string resource contains:
JQuery.blockUI.code = \
$.blockUI({\
message: 'h1Please wait.../h1',\
css:{\
border: 'none',\
padding: '15px',\
backgroundColor: '#000',\
'-webkit-border-radius': '10px',\
'-moz-border-radius': '10px',\
opacity: '.5',\
color: '#fff'\
}\
});
Thanks for your help

Note that FormValidator is our implementation of AbstractFormValidator

Re: Validate, Navigate Wizards
Hi
Just one note - I just had another look at our FormValidator class - you
might wonder why you won't find the method error (FormComponent fc,
String resourceKey) provided in my example. The reason is, we wrapped
this to provide a direct access to localized error messages in our
custom FormValidator:
/**
* Reports an error against the validatable using the given literal
resource key. This means, no
* class prefix is prepended to the resource key.
*
* @param fc form component against which the error is reported
* @param resourceKey The resource key to use
*/
@Override
public void error (FormComponent fc, String resourceKey) {
fc.error(fc.getLocalizer().getString(resourceKey, fc));
}
Just calling error (Serializable message) inside your form validator
implementation will of course report the error against the FormValidator
and not the failing component.
So make sure you callmyTextFieldThatFailed.error(...) instead of
error(...)
The Wizard will later test, if all contained components were successful
and only advance if none of them had its FormComponent.error() method
invoked.
Good luck
Matt

Re: Validate, Navigate Wizards
Hi
If you only want to require that a radio button is selected, then
myRadioGroup.setRequired(true) already does that job. No need to
implement a custom form validator then.
BTW: RequiredTextField is nothing other than a TextField which calls
setRequired(true) in the constructor.. It's only here for convenience
since it is used very often.
so, .setRequired(true) is your friend as long as you only want to
check if a radio button has been selected.
Matt

Hi,
my intention is to check if special mandatory fields are filled.
What I found in the examples is the RequiredTextField... within the Wicket
lib.
I use a RadioBtnGroup with RadioBtn's, the user has to select one!
Thats all what I validate.
But no matter, with your hint I can solve that problem. Maybe I implement an
own RadioBtnGroup-Komponent who can check this in general, like the
RequiredTextField... :-)
