Re: Why isn't my stateless form recreated from page parameters automatically?
Hi
it seems that
item.add(new TextField("itemId", new
PropertyModel(item.**getModel(),
"itemId")));
should be
item.add(new TextField("itemId", new
PropertyModel(item.**getModelObject(),
"itemId")));

Fragment caching???
Hi is there something equivelant to fragment caching in wicket? I mean , is there any way to cache the generated markup of a component, and on subsequent requests it just render this markup string? if so, how one can store these fragments in external store? how that can be configured or plugged in? to use some central caching like redis or memcached thanks Joe
Re: serialization problem with spring
Hi

actuallly it cannot serialize a JdkDynamicProxy which is the basis for

Re: serialization problem with spring
Hi
i am living on the edge ,using wicket 1.5RC5.1 (the latest)
and also using the newly released Spring data-jpa project for data access
i do not use or reference PersistenceExceptionTranslationInterceptor
directly, actually i never know it is there till i saw that error
based on its name it is an interceptor which translate the jpa or jdbc
exception to spring's counterpart
in AccountManager there is an instance of AccountDAO which use this
persistence technology
i thought it might be a solution to use kryo serialization as it does not
require the object to be serializable, but the site does not recommend using
it in production as it is in its early stages and not yet stable
Any help please?
Thanks

is there any way to externalize wicket-event.js
Hi, I for looking at ways of optimizing a wicket application. And, while a 304 is returned for wicket-event.js requests, the resource content is returned as well. Is there any optimizations that can be applied here? Ideally I would like to host these files (and probably change their name to have the wicket version) directly through Apache. I have poked around in the code and all I can see to do is change HtmlHeaderResolver. But since this is in Application.internalInit I am hesitant to do so. Any suggestions would be appreciated.

Generic Search Form & Results Display
Hi, I am new to wicket and I'm having trouble determining the correct way to
implement a generic search page.
I created a page that contains a custom form panel for the search parameter
input, and a DataTable for displaying the results. The DataTable uses a custom
DataProvider which takes a condition object that is used to perform the find.
The condition is initially null, which causes the DataProvider to return all
objects - this works fine, and so does the navigation toolbar I added to the
table. (I'm attaching example code below.)
My question is: what is the correct way to update the table's contents? I have
the form panel's onSubmit() call onFind(), which creates a new condition
object, but I'm not sure what to do with it.
Should I have the onFind() method add a new DataTable with a new DataProvider?
Or keep a reference to the table and set a new provider? Am I on the right
track or way off base?
SearchPage.java
-
private EntityCondition condition = null;
SearchPage(String entityName) {
add(new SearchFormPanel("find", entityName) {
public void onSubmit(Map searchParameters) {
onFind(searchParameters);
}
});
IColumn[] columns = ...
EntityDataProvider entityDataProvider = new EntityDataProvider(entityName,
condition);
DataTable table = new DataTable("results", columns,
entityDataProvider, 10);
table.addTopToolbar(new NavigationToolbar(table));
table.addTopToolbar(new HeadersToolbar(table, null));
add(table);
}
protected void onFind(Map searchParameters) {
condition = makeCondition(searchParameters);
}
...

Re: Announcing the Topicus Dashboard
@Martijn - I work at Atlassian and was one of the organizers of the campaign. Thanks for your *awesome* entry and I appreciate your critiques below. :) We did think about the problem of the community vote favoring the early entries. Our rationale for having submissions and entries end at the same time included a couple factors: * Timing: Due to internal timing constraints we knew the 4 week contest was going to bump up against Thanksgiving, where a lot of US-based participants would be out of town. * Inevitability: Even a week or two extra could be too little to overcome an early leader. So, like any community vote (e.g. http://musicmachinery.com/2009/04/27/moot-wins-time-inc-loses/ Moot's gaming of the Time Poll ), it's often an imperfect balance. * Non-voting categories: We made the community prize the least significant and included two other judge-ranked categories to incentivize entrants and reduce the impact of community voting / timing. * Simplicity: We felt that entrants would most excited about sharing their entry when they submitted it, and for those not interested in a vote rush, it could've dragged out the campaign. As for how it ended up - the winner of the community award Walle-D entered the contest about halfway through and upset early favorite Willow Creek (who had a two week head-start). So the simultaneous deadline didn't end up being a impossible barrier. That all said, we're listening to everyone's feedback and promise to do a better job next time. Feel free to hit me up @ jlambe at atlassian dot com with any other thoughts. P.S. It doesn't look like you filled out the https://atlassian.wufoo.com/forms/the-ultimate-wallboard-tshirt/ Ultimate Wallboard t-shirt form - I'd be willing to let you enter late if you want a shirt - but you'll have to hustle and get it in today! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Announcing-the-Topicus-Dashboard-tp3058300p3092976.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: strange problem with redirect to buffer and URL encoded query string
Thank you very much for the response, Igor.
After looking into this further it seems we might be having problems
with MobileAware. AFAICT their implementation of encodeRedirectUrl
and sendRedirect perform URL encoding differently. Thanks again.

strange problem with redirect to buffer and URL encoded query string
Hi,
I am using a AjaxFallbackButton within a form. In this case the
response is saved to a buffer in the session and supposed to be
retrieved in the next page request.
The problem that I am facing is that the second request is providing
URL encoded query string and I can't figure out why... Here is what I
have tracked down:
The redirect is set by the listener interface request target:
boolean issueRedirect = (strategy ==
IRequestCycleSettings.REDIRECT_TO_RENDER || strategy ==
IRequestCycleSettings.REDIRECT_TO_BUFFER);
* I am set to REDIRECT_TO_BUFFER
In WebApplication.addBufferedResponse, we are properly adding the
buffered response to the map with the key of "wicket:interface=:0"
In the BufferedWebResponse, we are calling
httpServletResponse.sendRedirect(url) with the value of
"wicket:interface=:0"
* note: the value is URL encoded but even after encoding does not
change from "wicket:interface=:0"
On the next call, the query string retreived in WicketFilter (String
queryString = servletRequest.getQueryString();) is
"wicket%3Ainterface=%3A0%3A%3A%3A%3A"
This causes the call to webApplication.popBufferedResponse to execute
with the wrong key which of course finds no buffered response.
* I have verified at this time that the valid buffered response is
still there under the key of "wicket:interface=:0"
* I do get a response back except that all component error messages do
not show up because they were rendered to the buffer.
Can anyone please help me understand what is gong on here? I have
tried evaluating this in firebug to see where this strange URL
encoding is coming from but all I see in Firebug when I look at the
response is "Failed to load source for:
{context}?wicket:interface=:0:wizard:form::IFormSubmitListener::. I
am using Wicket version 1.4.12 on Ubuntu and have tried this in both
Chrome and FireFox with the same result.
Any help would be greatly appreciated. Thanks.

RE: sanity check request for fix regarding the dreaded PageExpiredException
Thanks Igor and Alex for the feedback. It is very much appreciated!

So your "lost url" bullet can be fixed if you use some url creation strategy that solidifies in it enough of the path that you can recreate your "last page" location Then maybe add the important parts of the user state to the same strategy and you are there.

sanity check request for fix regarding the dreaded PageExpiredException
Hi, I know there have been several existing topics around this issue (http://apache-wicket.1842946.n4.nabble.com/debugging-PageExpiredExceptions-td1882040.html) for example. The reason that I am asking for a sanity check is because I plan to use an alternative approach to solving this issue and would like feedback to make sure there isn't a reason I shouldn't be doing this. The common approach is to catch the exception and return a new instance of the requested page. This seems to have some key drawbacks IMHO: 1) this only works with bookmarkable links 2) you lose any modifications to the model that happened after the page was originally loaded but before the exception occured 3) any data on the client may potentially be out of sync with the server state if not updated by the request that caused the exception (because the new page was loaded but that client representation is still a picture of the previous page with the previous model). Although this would be resolved by a form submit behavior - you would still have problems in the exceptional cases where the model is updated individually by input field ajax change events. It seems that the page version number is only necessary for a stateless application and in an ajax-oriented application you would always want to work with the latest page version. We seem to hit these issues when multiple ajax requests that target a particular page happen concurrently because the page version is incremented when the initial ajax request is made but all other ajax requests that are initiated before the initial ajax request response reference a now outdated page version number. So, after all that background - do you think this is a valid fix for an ajax-oriented application: Override the default SecondLevelCachePageMap and as long as the requested page id matches the page id of getLastPage() just return the last page. Your thoughts would be appreciated and sorry for the long email but I wanted to provide background to make sure that the fix was valid for my particular solution (because I know the fix would not be appropriate for a stateless application). Thanks Joe Hudson
rendering Wicket components to HTML
Hi,
First of all, before I get flamed - I've seen many topics about this since I've
been looking into this:
http://www.mail-archive.com/users@wicket.apache.org/msg27512.html
http://www.danwalmsley.com/2008/10/21/render-a-wicket-page-to-a-string-for-html-email/
http://apache-wicket.1842946.n4.nabble.com/Wicket-PDF-Page-Project-td1934168.html
My problem is that I am trying to get the rendered contents of a Page to
hopefully post process it and make a PDF out of it (using Flying Saucer) -
because of this I need to reference the currently running application for the
WicketTester (otherwise the application properties aren't available)
So, the standard WicketTester approach looks like this as far as I can tell:
public static String toString(Class pageClass) {
final WicketTester renderer = new WicketTester((WebApplication)
Application.get());
renderer.startPage(pageClass);
String renderedSource = renderer.getServletResponse().getDocument();
return renderedSource;
}
The problem with this approach is that the init method of the application now
runs twice (once when the app starts and once when this code runs). This is
causing an error because we are mounting resources which don't like being
mounted twice.
I have tried the other approach suggested from Dan Walmsley and haven't had any
luck with this either - can anyone get this to work? Am I just making this
terribly hard on myself - is it really this complicated to render a Page to a
String? Thanks very much for any feedback you might be able to offer.

Re: efficient resource downloading
Hi dear
actually , access control and dynamic file generation requires using
services which is injected by spring
this cannot be easily done in pure servlet
my current solution using spring @Controller and write diretly to the
servlet response is somethingvery similar to writing a servlet
but as i am planning to deploy on appengine, the startup time for spring
especially when using spring mvc cannot be accepted (more than 30 sec)
so i am tring to figure out a pure wicket solution
thanks for your help

efficient resource downloading
Hi
i want to know if this is an efficient way to download some files
i want my users to be able to download certain files just to registerd users
only so i can put that logic in the page constructor
but is this efficient way to do this as this may be called thausands of
times per hour (the files generated dynamically)
does the construction of a page and all the other bits is heavy for such a
task
i am using spring MVC right now with its rest style model and annotation but
it seems to me too heavyweight for the task
so is this appropriate?
is there another way more efficient?
public class DownloadManagerPage extends WebPage{
private static final long serialVersionUID = 1L;
public DownloadManagerPage(PageParameters parameters) {
super(parameters);
if (registeredUser(parameters)) {
getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(new AbstractResourceStreamWriter() {
private static final long serialVersionUID = 1L;
public void write(OutputStream output) {
output
}
public String getContentType() {
return ..;
}
}));
}
}
private boolean registeredUser(PageParameters parameters) {
return ;
}
}
thanks in advance

about serialVersionUID in all components
Hi all what are the side effects of setting serialVersionUID on all page classes and components private static final long serialVersionUID = 1L; i am developing an application which will be deployed on appengine appengine handle sessions by storing them in the memcache and data store as there is no local filesystem for its memcache everything must be Serializable, and as the session is stored in the datastore , your session may last for several weeks even if the web container expires it Ok, when i develop my classes may change a lot hence the auto serialVersionUID changes, making appengine complain as its session does not expires anyway , i think setting private static final long serialVersionUID = 1L; on every component will resolve it on appengine side, but ,what about wicket side? does it have any implications or side effects? thanks Joe

GAE serialization issues
Hi everybody i am developing an application on the GAE/J platform using wicket as i read through this list ,it seems that it is not a recommended combination due to some issues , specially the serialization issue BUT i have to deploy on appengine, so what is there any recommendations? OK, the real question is: does anyone used the custom PageStore implementation described in: http://letsgetdugg.com/2010/02/07/clustering-wicket-for-fun-and-profit/ or in: http://www.mail-archive.com/users@wicket.apache.org/msg46421.html in production and found that of real help? if so which one is better? what are the side effects of using each? can i have an implementation that fallback to normal sessionStore? Another question as its related to seialization, can using JBoss serialization lib make difference in GAE case? as it is much faster if so where are the hooks , or the interfaces to replace the default serialization BTW. i know it cannot be used in the core wicket due to its LGPL lic. Thanks Joe
using selenium
Hi all i am building an application which use ajax heavily so i have to use component.setOutputMarkupId(true) this generate unique dom id for the components which changes every time i load the same page when using selenium , specially with its Firefox ide , it depends mainly on the id attribute value and as this is dynamically generated by wicket ,it cannot work smoothly i can use xpath, but i then will lose some of the benefits of both selenium and wicket, selenium , i cannot use its code generation capability as it generate code based on the the id of wicket(designer friendly markup) as i cannot freely change my markup, otherwise it will break my tests what is your experience thanks in advance Joe

how to have an html id in markup and support ajax behavior?
Hello, I need a component to have an html id that I set in markup because I'm referencing it in other places. I also need to have the setOutputMarkupId(true) on the component because I need to support ajax behaviors. The problem that I am facing is that when I call setOutputMarkupId(true) it overrides the static id I set in the markup. Is there any way I can deal with this? Thanks. Joe

RE: is it possible to somehow create a url to return the contents of a panel
So, it is looking like I could do something like this:
Link link = new AjaxLink(componentId, new
Model("View Details")) {
@Override
public void onClick(AjaxRequestTarget target) {
String resultHTML = convertPanelToHTML(); // I
understand this
// how can I override the target response with the
result HTML?
}
};
1) I just want to return straight HTML (not contents within the
node)
2) I need the link to return the contents directly (not handle the contents
with the Wicket ajax javascript code)
Is type of behavior possible? If not, does anyone have any other ideas as to
how I could show a dynamic tooltip with data retrieved using ajax? Thank you
very much.

RE: is it possible to somehow create a url to return the contents of a panel
Thank you so much for the response, that was very helpful.
So, I've got half of the equation figured out but now, I have the issue of how
to generate a URL that call a component that allows for a straight HTML
response.
Here is the issue now:
Component someMadeUpAjaxComponent = ... {
onClick(AjaxRequestTarget target) {
// return the component output
}
}
1) Is there a component (the someMadeUpAjaxComponent) that I can get a URL for
which will trigger the onClick method
2) I need to attach the URL for the component to a link - not add the component
directly - is this possible?
3) Given an AjaxRequestTarget, is there any way I can write out the HTML
response (as opposed to adding components for rendering)?
Because, the result will look something like this:
View
Details
I will then attach a tooltip to this link which will know that it can take the
href attribute of the link to obtain the tooltip content.
Thank you very much for any help you could offer.

is it possible to somehow create a url to return the contents of a panel
Hi - hopefully I can explain this clearly...
I understand that I can use the AjaxEventBehavior to refresh the contents of
any components that I have on the screen or add new components.
I am trying to use a tooltip to display additional details for grid data. I
plan to use a tooltip library which supports retrieving content via an ajax
call. The question is: how (or is it possible at all) can I take a Panel and
get a url that would return the contents of that Panel. I'm probably not
explaining this well so, here is an example:
AbstractLink link = createLink(IModel rowModel);
Private AbstractLink createLink(IModel rowModel) {
// I need to return a URL which would contain the contents of
the additional details panel
// for this particular row in the grid
// the tooltip library will use the href attribute of this link
to dynamically retrieve the contents of the tooltip when displayed
}
Any help or ideas would be greatly appreciated. Thanks.

Form Data Not Available When Testing a TextArea component
I have a very simple Wicket web page with one TextArea for data entry on a
form. This is contained in a NavomaticBorder. The form works properly, as the
data is successfully saved to the database when the Submit button is clicked.
My JUnit test fails however, because the data is null. I am using the setValue
method of the FormTester object, and when I step through the code can see the
value being saved. However, when I execute clickLink() and get into the form
submit method, the data is null. I even tried stepping through the Wicket
source code, but I can't figure out where the data gets lost.
Can someone help with this? Here is my test code:
WicketTester tester = new WicketTester(partSelectLicenseWeb);
tester.startPage(LicenseDataReplace.class);
FormTester formTester =
tester.newFormTester("navomaticBorder:licenseDataReplaceForm");
formTester.setValue("licenseCode", "xyz");
tester.clickLink("navomaticBorder:licenseDataReplaceForm:submitButton");
tester.assertRenderedPage(LicenseDataReplaceResult.class);
Page resultPage = tester.getLastRenderedPage();
numLicensesSaved = resultPage.get("numLicensesSaved").toString();
Here is my form HTML:
Copy and paste a license
code:
Here is my (simplified) web page code:
public class LicenseDataReplace extends WebPage {
TextArea licenseCode = new TextArea("licenseCode", new Model());
public LicenseDataReplace() {
class LicenseDataReplaceForm extends Form {
protected void onSubmit() {
String enteredCode = LicenseDataReplace.this
.getLicenseCode()
.getDefaultModelObjectAsString());
... save enteredCode to database
... navigate to next page
}
public LicenseDataReplaceForm(String id) {
super(id);
}
};
NavomaticBorder navomaticBorder = new
NavomaticBorder("navomaticBorder");
navomaticBorder.add(new Image("logo"));
navomaticBorder.add(new Image("message"));
Form form = new LicenseDataReplaceForm("licenseDataReplaceForm");
form.add(licenseCode);

is it possible to include script resources using the HeaderContributor above the WebPage component script references
Hello, I would like for the script included using a HeaderContributor to be
above references within the WebPage component head node. Is this
possible. The reason I would like to do this is because I would like to be
able to reference code from the script file which is included using the
HeaderContributor. For example:
--- Application class ---
// inside init method
addComponentInstantiationListener(new IComponentInstantiationListener()
{
public void onInstantiation(Component component) {
if (component instanceof WebPage) {
component.add(new HeaderContributor(new
IHeaderContributor() {
public void renderHead(IHeaderResponse response) {
response.renderJavascriptReference(new
JavascriptResourceReference(MyReferenceClass.class, "scripts/example.js"));
}
}));
}
}
});
// WebPage component template
<head>
<script type="text/javascript">
...
// I can't reference anything from the scripts/example.js because
the source reference appears below this in the rendered output
By the way, please tell me if this is bad code and there is a better way as I
am very new to Wicket. All code criticism is welcomed :)
Thanks.

using behaviors as borders - how to?
Hello,
I would like to add a behavior to a component which alters the HTML output
related to that component. I know that you can use setComponentBorder but I
saw a posting that mentioned behaviors were the more appropriate way to do this
as explicit component borders might become deprecated.
I am trying to do something simple like wrap a form component with a label.
For example:
Instead of a form component rendering as:
I would like the behavior to help the component to render as
Some Label
So, the label component would be responsible for wrapping the inner content
with:
Some Label {inner content}
Here is where I am at:
- I know I probably want to extend AbstractBehavior
- I know I probably want to use the beforeRender and afterRender
methods to do this
Would anyone be able to give me some pointers to get started on this? Thank
you very much.
Regards,
Joe
RE: javascript effects before an ajax call
How can you make the script sources that you reference in your web page show up
after the component & wicket script includes? (assuming you don't want to do
this inline)
I would like to override the Wicket.replaceOuterHtml function because I would
like to do some jquery dom post processing. But whenever I include javascript,
it is above all other script includes in the rendered output. To override, it
must be included below the Wicket script includes. Thanks.

Subject: Re: javascript effects before an ajax call
Here's the more readable version - corrected with help form Richard at
JWeekend... This is the easiest way to do the animation either side of
the Wicket replace function that I know of... If someone would like to
wrap this up into a nice behaviour for the Scriptaculous wicketstuff
library be my guest :) I probably will eventually if we get back to
the project that uses it.
<!--
var oldF = Wicket.replaceOuterHtml
Wicket.replaceOuterHtml=function(element, text) {
var parent = $(element.id).parentNode;
// the disappear animation
$(element.id).fade({ duration: 0.4, afterFinish: function(effect) {
// call replace function
oldF(element, text)
// render the appear animtion on the replaced element
$(element.id).appear({ duration: 0.4});
}});
}
-->

how to include head resources below generated component additions to head
Hello,
I would like to override some of the styles of components I am using in my
page. However, when I include a CSS resource at the head of my WebPage
component, the incude occurs above all of the component includes. Is there any
way I can specify for an include to be below component includes that I am using
inside my WebPage component?
For example:
Here is example markup for the web page component
Using some component here
The output is something like this:
http://localhost:8080/wicket/styles/style.css>"/>
http://localhost:8080/wicket/resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js</a>>">
http://localhost:8080/wicket/resources/org.apache.wicket.ajax.WicketAjaxReference/wicket-ajax.js</a>>">
http://localhost:8080/wicket/resources/org.apache.wicket.ajax.AbstractDefaultAjaxBehavior/wicket-ajax-debug.js</a>>">
...
...
The output that I would like to achieve is something like this:
http://localhost:8080/wicket/resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js</a>>">
http://localhost:8080/wicket/resources/org.apache.wicket.ajax.WicketAjaxReference/wicket-ajax.js</a>>">
http://localhost:8080/wicket/resources/org.apache.wicket.ajax.AbstractDefaultAjaxBehavior/wicket-ajax-debug.js</a>>">
...
http://localhost:8080/wicket/styles/style.css>"/>
Is there some kind of component or application setting for this? Thanks very
much for the help.

Re: Spring ROO & wicket
Hi deari think possibilities for integration is limited for the following reasons: ROO is using spring MVC for the web tier ROO utilize the REST pattern which is stateless by default while wicket strength is its ststeful nature ROO depends heavily on aspectj and spring tools if u use spring tools or eclipse , and u want use the data layer features of ROO , go ahead, this part is compatible with very much every web framework Joe On Sun, Jun 21, 2009 at 12:22 AM, Objelean Alex wrote: > Recently, I've discovered Spring ROO: a user customizable tooling that > enables rapid delivery of high performance enterprise Java > applications.

Re: Conversation scope in wicket
Hi dearfirst of all, why add another dependency,just for conversation handling, while we have in wicket a strong ground for it note: jsr299 is a big spec with a somehow complex lifecycle(which may not be compatible with that of wicket) and really complicated bean resolution strategy second: wicket components are not 299 beans, wicket is an unmanaged framework , u must create the components urself, not by the framework, which is a requirement for jsr299 what can be done with web beans, is to inject its objects in wicket components BUT u cannot manage wicket components as web beans , and for example inject them or handle there lifecycle Joe On Fri, Jun 19, 2009 at 10:43 AM, janneru wrote: > hi james&joe, > > which are the issues with clint popetz's current work on the > webbeans-wicket > integration (already contained in the webbeans preview) that you would > write > your own? > > cheers, uwe. > > > On Thu, Jun 18, 2009 at 8:05 PM, James Carman > wrote: > > > JSR-299 is somewhat of a moving target right now, so it's hard to stay > > up-to-date with it.

in your last code line , do you mean pmap.getName() instead of pmap.getId()
as i cannot find a public getId() in ipagemap

Hi alli am working on a prototype which i think will convince you that
conversation is an important concept, it is very onject oriented as wicket
is and has many use cases

yes, u r right, wicket can'nt be everything for everyone ,but the question
is how much this hook thing is the responsibility of wicket
do you really think wicket is only ui framework?with no scopes so why u
support sessions? conversation is much like sessions, it is just narrowwer

Re: Conversation scope in wicket
Hiyou mean: injecting webbeans conversation component in wicket component at
construction time
this is only what we can achieve with webbeans, as wicket component cannot
be webbeans components (wicket is unmanaged framework)
my idea is about native conversation support, which enable wicket component
to be the component and the target for injection in a natural wicket way
beside, why depending on external project when we have all the functionality
we need as wicket is stateful and each pagemap is a conversation(long one
which may be easily break down to smaller pieces)

Re: Conversation scope in wicket
Hican this functionality added to the standard wicket?
actually much of seam popularity came from supporting conversation scope...,
so i think that adding explicit wicket support will have momentum
i think that having just a store for conversation objects will be a good
begin
then we may add apis like beginConversation, endConversation
,joinConversation,mergeConversation ,suspendConversation,resumeConversation
and other concepts like workspace
what do u think?

Conversation scope in wicket
Hi alli need to implement something like a conversation scope in wicket i know that wicket is stateful by default and i can pass object o from page A -> page B But if Object o in page A which -> page B -> page C -> page D -> page E and i need Object o in page E ,that will be very tedious to pass o all throught the way from A > ..E also if i need to pass a large number of objects between a set of pages ,this will be a nightmare so How can i implement a Conversation object ala Session and store these objects there i thought of using the IPageMap as a key in this situation as it represent an open browser window or tab ie. conversation, but in a previous mail ,i 've been tald that it cannot be extended easily, and i cannot provide my own factory for one so, any ideas about the conversation scope? what do u think about the pageMap ? will it work? is it reliable? can the core team provide some hooks to implement something like IPageMapFactory? thanks Joe

status of the PageMap
Hi alli was wondering , what is the status of the pageMap? i saw in the wiki some articles talking about it will be deprecated, so is that true? i can see it in the 1.4 docs, is that for backward compatability or it still a essential part of the platform? How can i plug my own custom subclass of PageMap and make the framework use it instead of the stock ones thanks Joe
Re: IRequestTarget not serializable
hi dearu have to process the target during its lifecycle time and store that
result into something serializable for future use
so u have to make the decision during the first request where the request
target is valid not the second

302 vs. 301 Redirect
When you setRedirect(true), wicket does a 302, temporary, redirect. The basic rule of thumb in SEO is if you want to pass all authority to a different page use 301 (permanent). http://www.seotoday.com/browse.php/category/articles/id/477/index.php Thoughts on adding something to Wicket to support this functionality? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Matt Raible's ApacheCon presentation
Compare the java code to something in velocity/jsp like...
href="/path/to/something.jsp?id=${draft.id}"
...I know, I know...you really can't compare the 2 because wicket's
version can have a lot more functionality easily. But, your ABSOLUTELY
POSITIVELY right about paying with maintainability, except you still
have to maintain the HTML file, yuck.
99.9% of the time I am very very happy with Wicket and wish that
everyone used it. I hate working on JSP/JSF projects because "it's the
standard and blah blah crap crap".
I liked the last "Con" though. "Everything has to be done in Java" - I
know what you meant, but its still funny. I wish everything could be
done in Java, even the design. And I don't mean HTML+CSS, but some
magically awesome design engine that would output HTML+CSS.
With a Wicket application its A LOT easier to figure out where
everything is and how it gets there. OO w00t. Ah, the days of PHP/JSP
hell.

Re: Matt Raible's ApacheCon presentation
I agree with the "Too much java" statement. Sometimes you have to
create a bunch of stuff that would be a lot easier to do in a velocity
template. It only takes a couple of seconds more to do it, but it just
makes everything 'seem' bigger.
Example would be a link on a table...
columns.add(new LinkPropertyColumn(new Model("Delivery"), new
Model(
"change")) {
@Override
public Link createLink(final Item item, String
componentId,
final IModel model) {
return new Link(componentId) {
@Override
public void onClick() {
ReportStatistic reportStatistic
= (ReportStatistic) model
.getObject();
DraftProduct draft =
productService
.getDraftProduct(reportStatistic.getReportId());
setResponsePage(new
ReportDelivery(draft));
}
};
}
});

Re: Cache Panel
How would I render the component and stick the contents into a label?
If possible, I would like to do something like the following...
String render() {
String markup = cache.get();
if (cacheExpired || markup == null) {
markup = render();
}
return markup;
}
I know there is no "String render()" method, but this just shows what I
would like to accomplish.
Thanks!

Re: Cache Panel
There are some operations that are kind of complicated, rather than dig into those operations and try to cache things, it would be A LOT easier to just stick a cache in front of it all.

This is a Hibernate question, but Eelco's 'class reloading' post
reminded me to ask on this list. I asked in the Hibernate forums, but

thoughts/ideas.
* The Problem
Ok, so you have IoC where you inject services you want to use in other
services. Well basically I want to do something similar with my domain
model.
I have 3 different maven modules. (I have a lot more, but for
simplicity's sake)
1. user-module - Which contains a User.class with fields like
emailAddress, password, address information, etc.
2. accounting-module - which depends on user-module and need to keep
track of a user's pending account balance, posted balance, etc
3. mywebapp-module - which depends on accounting-module
Currently
If I want to get a user's account balance I have to
User user = userService.getUser("id");
UserBalance bal = accountingService.getBalance (user);
It gets very cumbersome trying to write a ton of different queries to
retrieve data from the different tables. For instance if I want to get
someone's account balance via their e-mail address a query exists in the
userService.findByEmailAddress(), but I have to write another method in
the accountingService to do this again.
* What Hibernate offers
1. Hibernate offers dynamic mode where you can persist fields via a
Map, but you have to set the mode on a 'per session' basis.
a. This solution could work if you could have POJO and DYNAMIC-MAP
in the same session. (which I don't see why this wouldn't be possible)
2. Hibernate offers dynamic components, but User.class has to know
about the dynamic components and they cannot be dynamically wired up.
* What I've been working on
Modules contributing fields to models of other modules.
Instead of UserBalance becoming its own class its now an interace that
'contributes' its fields (via getters/setters) to the User.class so I
can do this.
User user = userService.findByEmailAddress("[EMAIL PROTECTED]");
UserBalance balance = (UserBalance) user;
The only way I can think of to accomplish this is by creating new
classes via javassist/cglib.
1. I take User.class and see if there are any interfaces that want to
contribute their fields to User.class
2. I create a new class that extends User.class with the new fields,
User$Enhanced.class
3. Then for each class with a field User.class I replace it with the
newly generated class
There is one big downfall to this approach. You can't create classes via
the new operator.
User user = new User();
UserBalance balance = (UserBalance) user; <-- User does not implement
UserBalance, throwsClassCastException.
balance.setPending(0.0);
session.save(user); <-- Hibernate does not know about a User entity,
only the new User$Enhanced.class!
You have to create objects via a factory so the object is actually of
type User$Enhanced
User user = factory.create(User.class);
This is where class reloading would come in handy!
* Conclusion
I have not finished a prototype of this yet as there is a big learning
curve of (byte code engineering) playing with javassist.
I spent a whole day playing with this when I have other priorities, but
this could speed up development immensely.
Whoever read this, can you give me some feedback?
Think its a good idea?
Think a slippery slope of problems will unfurl once I get a prototype
running?
Are there any other existing solutions?
Thanks everyone!

Hi Everyone, We just launched http://beTurtle.com/ - A 'green' social networking site. If your interested in healthy living, sustainable practices, have 'green' questions or just want to make some new friends, stop on by. Let us know what you think, we would really appreciate it. It runs on Spring2, Hibernate3, Wicket 1.3 plus many other open source projects. Without Wicket and the other frameworks I wouldn't have been able to develop the entire site so quickly. Thank you so much everyone for the great framework and answering any questions I had. Joe Toth - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
FormComponentPanel and CompoundPropertyModel
I have a FormComponentPanel, I want it to get and set a property from the Form it belongs to who's model is a CompoundPropertyModel. When the FormComponentPanel is loaded, how can I get the backing model's object whether someone passes in a Model or it should get it from the parent? If my FormComponentPanel only has a (String id, IModel model) constructor this is easy. But I want it to also support CompoundPropertyModels from the parent. (String id) I have to initialize a couple of DropDown's with data from the model. Any thoughts? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
