SV: Bug of Wicket when iterate the form using iterator()?
The only problem right now is the cast to Component[]. The fix is easy, just change it to Object[]. The optimization makes a lot of sense and there is reason why it can't really be simple. The simplest explanation is that the (synthetic) array classes both extend Object but are not in the same inheritance tree: [L.../Component; / java.lang.Object \ [Ljava/lang/Object; Thus the casting fails (at runtime). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
SV: How to update base page panel from child page?
My question is how to ask the cart section to updates its state (and redraw it) from a child page? Just add the superclass element to the AjaxRequetTarget parameter. This means either holding a reference to it (e.g. a protected instance field) or better, use get(path:to:cart) to get at it. Remember that all elements that should be updated via Ajax needs to have called setOutputMarkupId(true) on them so that the Javascript libraries can adddress them. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Please Please Portlet
(using Netbeans, wicket 1.4rc2, glassfish v3, portlet-container from open-portal project) I thought the portlet-container in effect was dead since the Sun Portal is dead? They have ditched that in favor of a solution based on Liferay 5.2 called Web Space (codename WebSynergy during development): https://webspace.dev.java.net/download.html - note that it uses Glassfish v2.1 in case you require features from v3. Around here we use a patched snapshot of 1.4 (using an adapted version of the older portlet 2.0 patch) for Wicket portlets. (Or have I been sleeping and we get real Portlet 2.0 out of the box in 1.4 now?) I noticed some differences between what we do (which works :) ) and what you posted: 1) In web.xml we have a filter mapping for each portlet: filter-mapping filter-namebookmark/filter-name url-pattern/basic/*/url-pattern dispatcherREQUEST/dispatcher dispatcherINCLUDE/dispatcher dispatcherFORWARD/dispatcher dispatcherERROR/dispatcher /filter-mapping 2) We also declare the application in the filter element: init-param param-nameapplicationClassName/param-name param-valueno.nsb.intranet.bookmark.wicket.BookmarkApplication /param-value /init-param 3) You also seem to be missing an init-parameter for viewPage, in our case e.g. init-param namewicketFilterPath/name value/basic/value /init-param init-param nameviewPage/name value/basic/list/value /init-param though in theory it should use the application's getHomePage(), I guess... 4) We do not have anything in sun-web.xml, though I guess we would benefit from a shared classloader with Web Space. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

SV: How can I share text resources with multiple web applications?
There is no sane reason why anyone would put the html, js, css and properties resources in any place except *next* to the corresponding.java file. Your .java file can not function without the .html file. Your component will fail if the .properties file is not available. When the js file can't be found your component is useless. Correct for the *runtime* view of files, and a Maven build will combine the packages in src/main/java and src/main/resources so that the two are merged. What Maven likes, however is that at *coding* and *building* time that the Java source files, and their related resources, are in different root folders. The main reasons I have seen for this is resource filtering and support for multiple resource folders (sharing resources between projects for instance). Wicket goes beyond the call of duty to provide developers with the means to encapsulate your components, bringing Object Oriented design and programming to the web tier. Yes, but that's salesman talk. :) And is not at all affected by Maven's preferences. Moving the necessary resources outside the package folder into a separate directory structure breaks this encapsulation is definitely not the Wicket Way (tm). It retains the package structure, but the packages start out in two (or more) different root folders when coding, being merged in the build process. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Not any more than you can e.g. go to Ford Motor Co. and demand they make this and that modification to the design of the Mustang, for instance.

(Walton's famous the customer is always right has a corollary: If someone is wrong they simply is not a customer. :) ) It's up to the core committers to do the best job they can to make sure their consumers are getting what they need... Not unless you want to start paying them to do so, becoming their boss in the process. As they have pointed out, Wicket is not their job but their hobby of sorts. However: Since it is an OSS product you can download the source and modify it as much as you like (like I did when I applied the portlet 2.0 patch to the 1.3 and 1.4 trees locally), even creating your own fork of it if you so desire. You see, the consumers are also the potential workers in the OSS world: if only a group of users want a feature it falls on them to implement it. just because it's an OS project that we don't have to buy, doesn't mean that the project doesn't depend on people using it. It does, but if it does not suit people's need they will look elsewhere. There is a ton of web application frameworks out there to choose from.

- when loading the page from the browser, the URL is returned including the page parameters; Yes, that would be a GET-method request. - when updating through AJAX, the URL is returned without the page parameters.

Shouldn't the AJAX call incorporate these page parameters such that the results are consistent? Not necessarily: the programmer normally picks up the parameters on the other side of the HTTPServletRequest which deals with such differences.

Real solution: Use a hidden token that you use to check whether the
particular form already has been posted, and in that case just skip the
form processing and work on the already processed object, something like
this in onSubmit():
// MapString, DataObject objectmap...
// FormDataObject
String tokenvalue = form.get(token);
DataObject obj = objectmap.get(tokenvalue);
if (obj == null) {
// Not already handled
obj = this.getModelObject();
// TODO Persist or whatever
// Put in map
objectmap.put(tokenvalue, obj);
}
// TODO Operate on obj

AutoCompleteTextField, IConverter and required
I have an AutoCompleteTextField with a POJO model; I override getConverter() to return a converter that looks up the field value in the same list that getChoices() uses for filtering. Which works fine if you actually put something into the field that matches. However, if you type a non-mathing value, the converter returns null; this is AFAICS the correct way to deal with failed conversion, and I expected a validation message to that effect. However, instead the null value is accepted, and even though the field is declared to be required, the form is submitted, and when re-rendered the field is of course blank due to the null model value. Any ideas? Problem occurred in 1.4.0 and 1.4.2 (noticed I was using an old version and upgraded, but same behavior). Would it be better to use the TextField/AutoCompleteBehavior combo manually?

Re: Hello World Portlet
What I find unclear, is the way it functions. It extends a wicker portlet, but the application is ran from WebApplication instance that mounts EditPage, HeaderPage, and doesn't seem to have any direct link to the WicketPortlet. The link is via the filter mapping and page mounting. Case in point: 1) You use a WicketFilter in web.xml as normal, this is the one that knows of the Application. However, for the portlet case you need to add init-param param-namedetectPortletContext/param-name param-valuetrue/param-value /init-param to the filter definition so that it can detect the portlet API things like PortletRequest etc. 2) In portlet.xml you use WicketPortlet, but need at least two things : 2.1) To tell the portlet of the path. This would be the same path that the associated filter-mapping in web.xml: init-param namewicketFilterPath/name value/foo/value /init-param 2.2) Tell it the paths to use for the various modes, at least VIEW; These need to be bookmarkable, mounted Pages: init-param nameviewPage/name value/foo/view/value /init-param in this case the Application needs to have mountBookmarkablePage(/view, SomePage.class); Note that you normally either need one Application per portlet, or few ones with multiple Pages mounted for the various portlets. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

As for the options: * Restlet: Implemented the REST ideas in a custom way before JAX-RS was specced, spec support seems crowbared in * RestEasy: Is a JBoss project, and there is as always a certain danger of the fish hook that leads you into the rest of the JBoss stack. Now, we are probably going to use JBoss ESB for some service orchestration, but their ESB will not support REST-based services (I think only Mule and ServiceMix do at the moment) until the 5.0 release which is a way off. * CXF: Axis and Xfire had a child, but it might be that it ends up as a bloated mess since they are trying to implement all sorts of services in one library. We do use it for SOAP services though. What you need to be aware of is that the JAX-RS spec is purely server oriented, and each implementation adds its own extension (like client libraries and proxying, content type support, JAXB/JSON magic etc.) so you do run the risk of vendor lock-in whichever you pick. But can you really have vendor lock-in over free stuff? :) Wicket could conceivably be morphed into a top layer to REST services (human-oriented interaction using forms and resource links), but to work seamlessly you probably end up with some very hairy URL coding strategies, resource models etc. that could make wicket-rest break Wicket for ordinary MVC purposes if running in the same webapp... - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Breadcrumbs and raw URLs
We have an issue where we are using a CMS that provides an API for getting article components in a peculiar way: Links are sent over as a raw HTML element followed by a link element followed by the rest of the HTML. So a link like a href=http://foo/fie; is sent as 1. HTML: a href= 2. Link: EXTERNAL, http://foo/fie 3. HTML: Now, some of these links are article ids that we want to turn into wicket-extensions breadcrumb links in a BreadCrumbBar. Using the BreadCrumbLink does not work since we don't actually have a HTML template element to apply the Link to. Is there a way to use urlFor() or the like to create links that updates the breadcrumb model with our BreadCrumbPanel subclass for the linked id, i.e. IBreadCrumbModel.setActive(new ArticlePanel(...))?

Re: Breadcrumbs and raw URLs
Is there a way to use urlFor() or the like to create links
that updates the breadcrumb model with our BreadCrumbPanel
subclass for the linked id, i.e.
IBreadCrumbModel.setActive(new ArticlePanel(...))?
*crickets*
Anyway, I finally found the likely answer in the form of an extended
PageRequestTarget.
However, it seems the call to urlFor() returns a link that does not
invoke the code as expected; it just re-renders the same page and panel
instead of invoking my object. Am I doing something wrong regarding the
urlFor call? Does the request target object need to be registered
somewhere?
// ...
CharSequence urlFor = RequestCycle.get().urlFor(new
ChangeArticleRequestTarget(getPage(), token.getLinkData()));
public static class ChangeArticleRequestTarget extends
PageRequestTarget {
private String articleId;
public ChangeArticleRequestTarget(Page page, String
articleId) {
super(page);
this.articleId = articleId;
}
@Override
public void respond(RequestCycle requestCycle) {
Page page = getPage();
BreadCrumbBar bar = (BreadCrumbBar)
page.get(breadCrumbBar);
try {
ArticlePanel newPanel = new
ArticlePanel(articlePanel, bar, new
ModelInteger(Integer.valueOf(articleId)));
page.replace(newPanel);
bar.setActive(newPanel);
page.dirty();

SV: Wicket SWFObject
I just figured out that the deal is that SWFObject doesn't like to be set visible false on page load then visible true via Ajax. Any thoughts on how to get around this? Ajax in Wicket needs the page DOM to have an element with the id it is supposed to replace with the output of a (now visible) component; by default an invisible Wicket component has no output at all. The traditional way to overcome this is to call setOutputMarkupPlaceholderTag(true) on the (initially invisible) component when you add it; that will make Wicket insert an empty element with the required id. (It also implicitly calls setOutputMarkupId(true) which is something else that the Ajax support needs to work properly.) - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
SV: Component creation and initialization
2 - A constructor is for constructing - your object should not be in an incomplete state when the constructor is finished (such a state that methods such as isVisible can not be called) Tha language ensures that the object is complete when the constructor exits, but with the exception of immutalbe objects, as a component it is not complete. People are e.g. adding to lists at runtime, leading to possible subcomponent initialiation later on in the relevant method of a Loop or ListView for instance. It could also be argued for instance that a LoadableDetachableModel is /intentionally/ incomplete when the constructor exits. Overriding methods like isVisible() is also a form of hack to postpone a property value to a later time (basically the component stops having a real property called visible since the setter modifies a variable that the getter does not care about). The desire to have completeness after constructor completion also runs afoul with modern ideas like IoC where it is left to an outside agent to complete configuration of a component. However, I agree that the attention of the thread originator should be on the models. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Custom FeedbackPanel in portlets
I made a FeedbackPanel to apply the Portlet 2.0 CSS classes to relevant messages. In my naïvetè I assumed I could just override getCSSClass(FeedbackMessage), but that is called both to set a style on the li item AND on the contained span element. Is there any reason for this, especially since the HTML template has class attributes on both of them and thus applies it to both? I ended up making a HTML template leaving out the class attribute on the span, but still...

Re: inserting urls in script variables
param name=file value={{URL HERE}}
Put some wicket:id on that, then add a WebComponent for it that you add
an AttributeModifier to, which sets the value attribute.
When I try to do the obvious, replace the {{URL_HERE}} part
with span wicket:id=downloadMsf/span it complains
about non-valid XML and such.
There are basically two groups of web frameworks:
The strict group parses the HTML in the templates and (if they use
their own tags) requires the templates to conform to XHTML syntax. Tags
and attributes specific to the framework form parts of proper XML
namespaces. Wicket, Facelets and Tapestry belong to this group as far as
I know. These are the more powerfuil since they can manipulate the DOM
at render time while maintaining a designer-friendly template without
too much mess.
The lenient group only bothers with its own tags/commands etc. and
treats the rest of the template as just text that should be outputted to
the stream without a question about structure. JSP, Velocity, Webmacro
and many others belong to this group, which is large because it is far
easier to write parsers for this approach, for some definitions of
easier :). This is the reason you can do e.g. a href=%= url % in
JSP because JSP turns that into outputting of the string a href=\,
the value of url, then the string \. It never sees the a element.
However, since it deals with JSP and JSTL tags in the same step, you
cannot do e.g. c:if test=%= somevariable % but need to use EL
instead.
(Did I mention that JSP is a horrid mess and EL is just mascara on a
pig? Well, consider it mentioned. :) )

Does anyone know of a simple way to have more than one option

Well, how would you disambiguate between them? Null usually means
unset in the context of DDC, but here you have semantic meanings to
the choices, so they should be real objects.
A better solution is to have constant values that you treat specially,
e.g. if the domain objects are of type Name, add two elements at the top
of the list for the DDC.
public class Name {
public static final Name ANY_VALUE = new Name(-1, --- Any Name

How do I redirect to a mailto: url?

Re: Wicket pages as actions
http://localhost:8080/web/?wicket:interface=:3:logout::ILinkListener:: I don't see the need to expose implementation details (i.e. ?wicket in the URL) at this point. Therefore, does it make more sense that the LogoutPage (the response page) itself performs the logout action? The link for logging out would then simply become a bookmarkable link to the logout page. For some reason, this doesn't really feel right to me, though. It does make sense to me; in that case you just mount(/logout, LogoutPage.class); in your app, and sign out in a suitable method. Having it as a separate page you can also give a goodbye message to the user. I'd much rather keep the functionality as is and, instead, have the URL disguised. I do understand the basics of URL mounting and encoding but don't understand how I can use it to disguise this particular scenario.

SV: Portlet and ... 2.0 (How to pass parameters?)
But it will be the portlet class the responsible for handling processing. So the only way to pass information from the onClick function to the portlet application for rendering (for example) is using the portlet session. But why would you want to go via the Application? The WicketPortlet is mostly just the front controller responsible for mapping between the portlet world and the Wicket world: Either use a custom WebSession for the portlet app, or pass the values you need in the PageParameters you send to the response page in your onClick()/onSubmit(). This assumes the onClick() is for a link on a Page that is part of the portlet application. Rendering is left to these Pages. I also saw that in the portlet example, the examples structure is initialized by the WicketExamplesMenuPortlet and sent to the WicketExamplesMenuApplication using the servlet context. But this will overbloat the servlet attributes storage space. Also this should be solved if webpages could access to the portlet class directly. Why to do this way? The Examples portlet is a bit strange compared to how you would normally do things it seems. 1.- Onclick: Put the Id on the session like above. 2.- Portlet.DoView: Recover id from session and store it in shared render params. 3.- Delete it from session. Is this the correct way to do it? You could try making normal PortletURLs instead of using Wicket Link elements; use setProperty()/addProperty() to set the portlet parameter. Presumably Wicket's Portlet API implementation will deal with the mapping just as it does today with mapping to and from PageParameters. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Hi, I'm trying to use an upload progressbar, the problem is that it does not appear whent I use an ajaxsubmit button but appears when i used the form onSubmit method. what could be the problem. Possibly it starts out invisible, and in that case you need to call progressbar.setOutputPlaceholderTag(true) in order to have something there for Ajax to update. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
SV: Question on close button of modal windows
You could do it with JQuery directly, or implement WiQuery dialog. The latter is preferrable, because if you close a ModalWindow in the browser with no roundtrip then the server side state will not be notified that it is closed, and thus might reappear if the page is refreshed as a whole. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

SV: DropDownChoice problem
After adding the dropdown to the form, i am able to save the record properly. However, when i display a form with an existing record, the DropDownChoice is not showing the current 'nationality' and it is only showing Choose One; Sounds like Wicket gets confused regarding value/id, try setting an IChoiceRenderer, e.g. lstNationality.setChoiceRenderer(new ChoiceRenderer(name, id)); - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

i meant where do you expect the localized message to be rendered into? if wicket:message is attached to the table tag? Well, since he is using the attribute version of wicket:message, I guess he expects the output from table wicket:message=summary:myresource to be table summary=localized message with key myresource - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
SV: Error out in middle of page without filling in remaining components
Let's say you encounter an error halfway through the constructor of a page, and you want to display error(error message) and then return without processing rest of components? It doesn't seem like this is possible in wicket because it makes you fill in all components or else it barfs. Am I wrong, or is there a way to do this in wicket? 1) Ideally, a constructor does NOTHING other than - validate arguments, and throw necessary exception if they are wrong - set properties (no side-effects) that will be used by other business methods later In Wicket, Swing etc., the latter also covers setting up component hierarchies. So actual errors should only appear later, e.g. as a consequence of a LDM failing to connect to a database at render time. 2) If that is not an option, the way to interrupt a constructor is the same way as for any other method, throw and exception. For instance a WicketRuntimeException. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
TinyMCE + TextArea + Jackrabbit
Using wicketstuff tinymce 1.4.1 attached to a TextArea, it seems I cannot get it to stop escaping the resulting HTML: TextAreaString textArea = new TextAreaString(threadSubjectTextInput, new ModelString()); textArea.setEscapeModelStrings(false); TinyMCESettings settings = new TinyMCESettings(); settings.setToolbarLocation(TinyMCESettings.Location.top); TinyMceBehavior behavior = new TinyMceBehavior(settings); textArea.add(behavior); Obtaining value: String article = getForm().get(threadSubjectTextInput).getDefaultModelObjectAsString(); Setting property on JCR node: articleNode.setProperty(articleText, article); Rendering the output from the Jackrabbit Node: articleItem.add(new Label(forumArticle, article.getArticleText()).setEscapeModelStrings(false)); Is there some other code which might escape the HTML?

SV: Best practises question
Well, I think that's quite obvious when you consider that each page is the root of a tree (not directed, acyclic graph) of components. Each component can have at most one parent. But you can pass a component to a different page/component without adding it; like in the example of having a back link which wants a page to navigate back to. If you keep that Page in an instance variable in the back-from Page you will needlessly serialize that, too, unless you use a PageReference. - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

https://localhost:8080/test Typically, a container will have a HTTPS-enabled connector on a different port; in Glassfish by default it is 8181, on Tomcat it is by default disabled but seems to have the value 8443 in a default server.xml (443 being the assigned port that you need root/admin privileges to open).

Null from urlFor() on
We are trying to tunnel some images from a content system, and run into a
problem trying to make URLs for them via UrLResourceStream: Stepping through
the code we see some instanceof-testing but none which deals with this
particular resource type. Is there some missing code somewhere or a better
approach to use?
WebMarkupContainer cont = new WebMarkupContainer(image);
try {
URL image = new
URL(http://servername/servletname/path?parameter=velue;);
UrlResourceStream stream = new UrlResourceStream(image);
ResourceStreamRequestTarget target = new
ResourceStreamRequestTarget(stream);
CharSequence link = urlFor(target); // RETURNS NULL
cont.add(new SimpleAttributeModifier(src, link));
} catch (MalformedURLException e) {
e.printStackTrace();
}
this.add(cont);

SV: Very interesting question... my boss complain about one of my implementations...
My boss said that it is not a good practice and he recomended to use something like in Struts called Timers, do we have something like that in wickets¿? Try looking into Quartz, a library for such things. The lack of a standard scheduling framework outside of JMX is a problem in JEE in general... However, the Struts Timer seems to measure rendering time, so I am not sure why your boss thought that would help. http://struts.apache.org/2.0.11.1/struts2-core/apidocs/org/apache/struts2/util/Timer.html - Tor Iver
SV: DropDownChoice behaviour
I would like to know what's the outcome of setting setNullValid(true) - - is it that the choices will start with an empty string choice? The empty choice is there for null model objects whether nullValid is true or false, the difference is that if you call setNullValid(false), then the option will be removed for non-null model values, and if you try and submit the form using a null value it will fail validation. - Tor Iver
