Add input in javascript and process value in form?
Hi,
i would like to add some input fields to an ul/li using JS.
function add_fields() {
var d = document.getElementById("items");
var i = d.childElementCount;
d.innerHTML += "<li><input name=\"item:" + i + ":value\" /></li>";
}
Currently in Form.onSubmit values are empty.
Is this possible? Is there an example for this?
Thanks for your support

Extend session metadata with user-data-scope after login (spring question)
Hi,
i would like to extend a session (metadata) with scope of user logged in.
Something like "allowed countries", "allowed companies" and so on.
That scope is provided by a spring bean (UserScopeFinder). This bean is created
in a Configuration as a @Bean.
What i tried so far is add an ISessionListener to WebApplication and inject the
UserScopeFinder.
@com.giffing.wicket.spring.boot.context.extensions.ApplicationInitExtension
public class AuthorizationInitializer implements
com.giffing.wicket.spring.boot.context.extensions.WicketApplicationInitConfiguration
{
@Override
public void init(WebApplication webApplication) {
IAuthorizationStrategy strategy;
strategy = new ApplicationAuthorizationStrategy(new
UserRolesAuthorizer());
webApplication.getSecuritySettings().setAuthorizationStrategy(strategy);
webApplication.getSessionListeners().add(new
UserScopeInjector());
}
}
public class UserScopeInjector implements ISessionListener {
@SpringBean(name = "userScopeFinder")
private UserScopeFinder userScopeFinder;
public UserScopeInjector() {
super();
Injector.get().inject(this);
}
@Override
public void onCreated(Session session) {
System.out.println("Works");
}
}
But in that case i get:
...
Caused by: java.lang.RuntimeException: error while injecting object

But now i need to replace the additional web app by my wicket app. So far i do everything using rest resource. So i ask myself if there is a similiar component for SOAP.

Aw: Re: Wicket Spring boot - use spring devtools
Hello Martin,
the problem is that i assign a model in request cycle metadata by using the key
public class IdentityInstance extends MetaDataKey> {
public static IdentityInstance KEY = new IdentityInstance();
private IdentityInstance() {
super();
}
}
Page:
getRequestCycle().setMetaData(IdentityInstance.KEY, identityModel);
Widget:
IModel identity = getRequestCycle().getMetaData(IdentityInstance.KEY);
But the model in Widget is always null. While debugging i found that object
identity is used in Class#equals(Object o), what is ok for me.
But with different classloaders class is loaded multiple times.
I could provide a quickstart for this & create an issue, if you like. (?)
I would like to adapt my configuration so that devtools are still available.
(DCEVM i need to inspect :-).)
Thanks for your support.

Can I use wicket to emend my markup?
Hello, i try to render HTML markup with flying saucer to PDF. In case i render the page by wicket and use that result markup in my flying saucer wicket resource, everything is ok. Because i need to generate some SVG by browser using javascript (d3.js) i would like to send the markup from browser to my FS wicket resource. My main problem is that sending the html by using document.documentElement.outerHTML destroys the markup. It cuts of the end-tag from my link element. So the flying saucer complains on a missing link end-tag. Example My original html looks like this http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;> Apache Wicket Quickstart Apache Wicket after sending result of document.documentElement.outerHTML as form-data to wicket resource i receive http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;> Apache Wicket Quickstart http://localhost:8080/style.css; type="text/css" media="screen" title="Stylesheet"> ... The meta and link end-tags have been removed (i suspect the browser doing that). Flying saucer complains then with 1:36:41.764 [qtp2116908859-19] WARN RequestCycleExtra - Handling the following exception org.xhtmlrenderer.util.XRRuntimeException: Can't load the XML resource (using TrAX transformer). org.xml.sax.SAXParseException; lineNumber: 6; columnNumber: 4; Elementtyp "link" muss mit dem entsprechenden Endtag "" beendet werden. at org.xhtmlrenderer.resource.XMLResource$XMLResourceBuilder.transform(XMLResource.java:222) ~[flying-saucer-core-9.1.6.jar:?] at org.xhtmlrenderer.resource.XMLResource$XMLResourceBuilder.createXMLResource(XMLResource.java:181) ~[flying-saucer-core-9.1.6.jar:?] at org.xhtmlrenderer.resource.XMLResource.load(XMLResource.java:84) ~[flying-saucer-core-9.1.6.jar:?] at org.xhtmlrenderer.pdf.ITextRenderer.setDocumentFromString(ITextRenderer.java:161) ~[flying-saucer-pdf-itext5-9.1.6.jar:?] What i would like to know is - can i send the markup to a "wicket class" and emend the corrupt tags?

My main problem is, that i can not send the svg text to the resource. Doing so

Aw: Re: Use Resource to transfer SVG to PNG
Thanks for your response Martin.
I tried to make it work the whole day now. But i can not get it to work with
IE11.
There is always a security error. This is a known problem for IE and canvas.
I ended up:
$("#chart-export").on("click", function() {
var svg = document.querySelector( "svg" );
var svgData = new XMLSerializer().serializeToString( svg );
var canvas = document.createElement( "canvas" );
document.body.appendChild(canvas);
var svgSize = svg.getBoundingClientRect();
canvas.width = svgSize.width;
canvas.height = svgSize.height;
var ctx = canvas.getContext( "2d" );
ctx.clearRect(0, 0, canvas.width, canvas.height);
var img = document.createElement("img");
img.setAttribute("crossOrigin", "anonymous");
img.onload = function() {
ctx.drawImage( img, 0, 0 );
var a = document.createElement("a");
a.download = "chart.png";
a.href = canvas.toDataURL( "image/png" );
document.body.appendChild(a);
a.click();
};
img.setAttribute("src", "data:image/svg+xml;base64," +
btoa(unescape(encodeURIComponent(svgData))) );
});
So i need to go on the other way. But there my problems still occur.

Use Resource to transfer SVG to PNG
Hello *, I would like to generate a png from a svg. The transcoding is done by using Batik. So far it works as expected. But i'm not sure how to provide the resulting png (a byte[]) to my frontend. The svg is generate in browser by using highcharts. I would like to provide a button that downloads the transcoded png by sending a request to the "transcoding resource" and using the svg-dom from browser. Is there someone who did that already once? Can you please give me a hint how this could work?

Aw: Re: Re: ListItem and enclosure problem
But wouldn't this only hide the complete listview when there is no item?
I want to remove markup only for an empty item.
So something like
1
2
3
should become in case foo:1:bar is invisible
1
3

Aw: Re: ListItem and enclosure problem
Sorry Ernesto for my bad english. But i can not see how i shall get this to
work with a panel?
I use a listview because my item count is configurable. So i can not generate a
"template panel"
and put all items in that. But i admit that i didn't understand your question
completely.

Aw: Re: ListItem and enclosure problem
Thanks for responding.
Maybe i should have stated my goal clearly. I would like to remove the space
occupied by empty list items.
Basically i do it with wicket:enclosures. While not displaying the "empty
element" markup the space is not occupied.
Do you mean that i need to change it that way?

ListItem and enclosure problem
Hello,
i would like to enclose markup of a list item in wicket:enclosure. The

So for i could not find any marker that this is not working. So i need to do
something wrong. Any work around would be welcome.

Find a component corresponding to entity
Hello *, I'm looking for an elegant solution to determine a component for an entity. Example: There is a person and two sub-types of it - Manager and Sportsman. The Manager can be listed in a listview by using a ManagerViewItem and the Sportsman by using a SportsmanViewItem. Currently I'm using a factory producing the appropriate viewitems. But this factory is injected by using spring. I would like to reduce the coupling to spring within my component classes (e.g. Page). So i'm looking for a "wicket way" to determine which component is required to list all persons. Thanks for your ideas.

Re: Tool for finding missing translations in properties.xml
I wrote my own tool as my search wasn't successful. But it is simply a main method loading the files and compares keys.

Re: Best Practice - Create component by entity type?
This sounds good. I already have a registry where i can register services in a
decoupled way. With spring and @PostConstruct no Problem :-). I would ASK then
every factory if it is responsible for my entity type. But i still see a
problem here. How to prioritize factory if i have more than one factory for a
Person type. For instance if a boss is a manager. Then i can't use instanceof
in the manager factory because boss entity would match twice.

Hi Per,
You can do something like this:
Create a set of compontents that will be your panels to display specific
Persons.
Let's call them PersonPanels.
You can introduce a PersonPanelFactory, which might give you the
appropriate PersonPanel based on the class of the Person (
person.getClass() ) . This is however not yet nicely extensible, but you
decoupled the logic for creating panels from your list-code.
Next step: you need to register the classes somehow so you can provide
panels for in the factory, so the factory can for example use a map to
provide the proper PersonPanel. You can use reflection to call the
constructors, which will need to have the same arguments for their
constructors. This is the biggest disadvantage I think in this approach.
Somewhat like this:
class PersonPanelFactory
{
public PersonPanel getPanelFor( ClassT extends personClass) ...
public registerPanelFor ( ClassT extends Person personClass, ClassT
extends PersonPanel personPanelClass ...
}

How can i avoid that urls in src attributes are handled by wicket?
Hi *,
we have a page which contains markup like this
...
script type=text/x-handlebars id=template
img src={{ url }} alt={{ name }} /

...
After rendering the page the markup looks like this
script type=text/x-handlebars id=template
img src=../{{ url }} alt={{ name }} /
/script
Please note the ../ before the {{ url }}
Until now i thought that wicket handles only markup within html tags containing
a wicket:id.
But it seems that Wicket gone wild here :-).

Is Behavior.beforeRender useful for component configuration?
Hi,

I would like to hide the admin item in main menu if no menu item is

It tries to hide parent by checking if all items are invisible and
configure the parent's visibility.
But this is not working (configure(component) and beforeRender(component)).
Configure is not usable because the render permission (setRenderAllowed)
is determined after the Behavior.onConfigure was called.
So the action takes place before the child is authorized.
Then i thaught let's do it in beforeRender. But there we got a message

Sadly i can not use Behavior.configure(Component). The code will be
executed (see Component.configure)

[auth-roles] Design of x-RoleAuthorizationStartegy
Hi,
we had a simple usecase today leading us to confusion on
AnnotationsRoleAuthorizationStrategy (ARAS).
We tried to protect a button by using two different permissions. So we had to
use AuthorizeActions.
We did it this way
code
@AuthorizeActions(actions = {
@AuthorizeAction(action = Action.RENDER, roles = { entity.create }),
@AuthorizeAction(action = Action.RENDER, roles = { document.fillout })
})
private static class NewDocumentForNewEntityLink extends
BookmarkablePageLinkVoid {
public NewDocumentForNewEntityLink(String id, Class? extends WebPage
pageClass) {
super(id, pageClass);
}
}
/code
Ok we don't use the roles as their name would suggest it. We use it more as
permissions.
But that is not relevant here (IMHO).
In one of our test cases we've found out that only one permission is required
to get
that link displayed. But we would like to include all permissions. And so the
story begins.
The first maybe intuitive way to customize the annotation handling was to
implement our own
IRoleCheckingStrategy. But the first issue we had was the name of the interface
method we
had to implement (hasAny(Roles)) which suggests an or condition.
= Isn't this to thight for an interface? Shouldn't the name be accepts(Roles)?
With further checks we saw no chance to get an and condition check done by
the current
ARAS implementation. The only possibility was to overwrite
code
protected boolean isActionAuthorized(final Class? componentClass, final
Action action)
/code
and do it by our own. Another problem could be the handling of the deny
permissions.
If we would like to use an or condition check here this wouldn't be possible
because
accept and deny checks use the same method (hasAny(Roles)).
= Shouldn't the role check a task of the RoleCheckingStartegy? Shouldn't it be
a more
configurable implementation?
I hope my problem got clear. I don't want to snub anybody. The intention of
this is
only to have a discussion here before we create a ticket with a patch.
What do you think?
Thanks for your opinion

Hi,

Hi,
Are you saying that the event of clicking the bookmarkable link (the a)
bubbles to the div ?
I think it should not happen. Clicking the link changes the document
location... But I may be wrong.
A simple solution is to add onclick=Wicket.Event.stop(event); return
true; to the a element.
This calls event.stopPropagation().

public class ReplyOptionsCollectingModel implements Serializable {
private ReplyOption answerForQuestion1;
private ReplyOption answerForQuestion2;
// ... getter and setter

repeating view.

Re: Wicket integration with Spring
With the 2nd approach you couple the application (in the role as service
mother) to all your calling components.
Coupling is a bad idea. It's hard to test in separation and almost
always you end in a hell of small single methods.
But if you inject your beans into the target component you can define
your required dependeny there were you use them.
Another cool approach in wicket is the event system in 1.5+. So you
throw events in child components and provide the
services in high ranking components (page, app ...)
Just my 2 ct.

Hi,
we had a similar requirement, so we did the following:
instead of throwing a AbortWithHttpErrorCodeException, we throw a
semantic exception. In your case, throw MissingSubsiteException( your
message ).
How to make Wicket aware of such an exception and implement a proper
reaction/response?
In your application's #init()-Method, add a RequestCycleListener (e.g.
extends org.apache.wicket.request.cycle.AbstractRequestCycleListener)
which implements #onException() to dispatch to a particular error page
depending on the exception passed in. AFAIK, this is regular Wicket
stuff and nothing terribly internal (right?).
We have a bunch of error pages which are regular WebPages with
#isErrorPage() returning true. Those are triggered via the mentioned
RequestCycleListener by means of a
org.apache.wicket.request.handler.PageProvider, which can be used to
initialize the page just as you may need it. For example, by passing the
exception's message, or the exception itself to also display the stack
trace.
Such an error page can also set a status code by using #getResponse() in
#onBeforeRender(), i.e. set a HttpResponseCode.SC_BAD_REQUEST for
missing parameters.
I hope this helps,
bye

Re: Why can't CssUrlReferenceHeaderItem have dependencies?
Hi Martin,
i use the UrlResRef like the normal ResRef. A specialiced css is depending
on a base css.
This base css should be guaranteed on special css usage.
public class PortalCssDependingResourceReference extends
UrlResourceReference {
private final String portalId;
public PortalCssDependingResourceReference(String resourceUrl, String
portalId) {
super(Url.parse(resourceUrl));
this.portalId = portalId;
}
protected final String getPortalId() {
return portalId;
}
@Override
public Iterable? extends HeaderItem getDependencies() {
ArrayListHeaderItem dependencies = new ArrayListHeaderItem();
for (HeaderItem headerItem : super.getDependencies()) {
dependencies.add(headerItem);
}
dependencies.add(CssHeaderItem.forReference(new
PortalCssResourceReference(this.portalId)));
return dependencies;
}
@Override
public boolean isContextRelative() {
return true;
}
}
It is included as expected with this (sample) code in my page. And this is
the cause why i'm wondering this is not implemented.
@Override
public void renderHead(IHeaderResponse response) {
final PortalCssDependingResourceReference reference = new
PortalCssDependingResourceReference(resources/special.css, getPortalId());

Re: Why can't CssUrlReferenceHeaderItem have dependencies?
code
response.render(CssHeaderItem.forReference(reference));
/code
created a css link like this:
link rel=stylesheet type=text/css
href=../../resources/portal/css/portal.css /
What i've tried to get is this:
link rel=stylesheet type=text/css href=/resources/trauer/css/portal.css
/
We have all our css in an external folder (apache DOC_ROOT static). So this url
is required.
But now i'm in doubt that i've misused the ResRef and HeaderItem concepts.
It seems to be more natural to extend the CssUrlHeaderItem and provide the
dependencies there instead of connecting this to the ResourceReference and
delegate the call. Maybe that is cause of how this is implemented.

Hi,
Why do you use reference.getUrl() to create CssUrlReferenceHeaderItem ?
Why not just : response.render(CssHeaderItem.forReference(reference));
CssUrlReferenceHeaderItem by itself works with plain Url and there is no
way how Wicket can know that it may depend on some other dependencies.

Why can't CssUrlReferenceHeaderItem have dependencies?
Hi, i was wondering why CssUrlReferenceHeaderItem (wicket 6.2.0) is implemented by HeaderItem#getDependencies() which returns an empty list. The CssReferenceHeaderItem has a getDependencies implementation which uses the dependencies provided by the resource reference. If i extend CssUrlReferenceHeaderItem (for testing) and provide the dependencies of the resource reference (analogoues to CssReferenceHeaderItem) everything works fine. But maybe i miss here something. So my question is: Is it required that CssUrlReferenceHeaderItem is not handling dependencies of the resource reference? Thanks for explanation.

Re: AutocompleteTextField and object (not just String)
Hi Daniele, while I don't have the answer to your question, here's a recent blogpost about how we implemented a reusable wicket autocomplete field. We were not entirely satisfied by the solutions we found about a year ago, so we cooked our own. There might be better solutions by now, and it's not a 100% native solution (uses jQuery UI, and a JSON action), but we keep using it a lot in our application for various use-cases, and it's been a huge help.

Is there a MountedMapper respecting better matching path names?
Hi,
before i do this myself i would like to ask the community if someone has done
this already.
I want to mount pages at these urls:
mountPage(/pages/${color}/advertise, AdvertisePage.class);
mountPage(/pages/${color}/${niceColor}, ColoredPage.class);
But because they both have 3 matching url path segments the first after sorting
all available mount mapper wins. But in this case the almost exact url
/pages/red/advertise is referencing the ColoredPage but should the
AdvertisePage. Only ordering the mounts is influencing the result. But this is
not a good option.
So i would like to know if there is already a library providing my required
behavior.

Re: Page/Session persistence on AppEngine
Hi Chris, we encountered similar problems, and wrote two blogposts: One about tweaking all the components, one about zipping the session. http://www.small-improvements.com/blog/technical/tuning-wicket-session-size http://blog.small-improvements.com/2012/02/19/reducing-wicket-session-size-to-one-third/ You should use a proper profiler (e.g. JProfiler) to figure out the size of your pages and objects, much more efficient than logging stuff youself. And then also you can also write a custom IPageMapEvictionStrategy that takes session size into consideration when evicting pages (e.g. you evict so many pages until the session size is below 1MB again). That's the last resort only, but helps avoiding the nasty blank exception page. All combined, you should be able to work around the session size issue.

Re: Performance optimization
Hi Martin, some of the things we did was (as mentioned by others) to generate HTML, this saved a lot of memory. But also to look really hard at the component tree and decide if everything was needed *all the time*. For instance, we had plenty of AJAX links that were rarely used (5 per row or so). We decided to make them load on demand only (click for admin actions). This saved some 500 bytes per row. Also, some optimisations like replacing setVisible(false) by an empty component saved us some space. Some component use more memory than others, and can be replaced. Etc. It's really crucial to use a profiler to see where all the bytes go. I wrote a blogpost over here: http://www.small-improvements.com/blog/technical/tuning-wicket-session-size a few months ago. You may even want to create your own eviction-policy that collects certain pages more aggressively than others (if applicable). Many options. But yeah, it's tough, it's one of the things I found most challenging about Wicket. I'd love to hear how you end solving with the problem, maybe there's something else to be learned! Good luck!

We've been using LDMs and all sorts of optimisations, but we were still reaching the limits when a user viewed long lists, or used many tabs, and as a result pages often got evicted while still needed, resulting in ugly page expired errors. Turns out, you can zip the session's attributes on the way out, e.g. on the fly, with minimal latency introduced. In over a year of squeezing bytes out of the object graph, this had never occurred to me. But now it's kind of obvious, and really easy to code as well... Check out our blog if you ever had this problem. http://smallimprove.wordpress.com/2012/02/19/reducing-wicket-session-size-to-one-third Cheers, Per -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Shrinking-the-session-size-simply-by-zipping-it-Saved-my-day-tp4402980p4402980.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: get key from resource model
If you mean get the key from ResourceModel, or ... then the answer is
no not directly.
An ugly solution could be - extend ResourceModel and memorize the key in
a second attribute.
But that's realy ugly.
class MyResourceModel extends ResourceModel {
private String key;
public MyResourceModel(String key) {
super(key);
this.key = key;
}
public String getTheKeyOnUglyWay() {
return this.key;
}
}
But i would do this only if no other solution is possible.
Cheers

Hello,
My displayed texts are localized using ResourceModel('my.key').
Is it posible to get the key for ResourceModel, or an object from whom I can
extract the key?
Thanks.

Re: StatelessForm: Cannot login
If i understood your usecase correctly you're app is still stateless if
you logged in.
Afaik no session is created for stateless pages. So after you've logged
in the session
is away for your next page. And then the user is away to. You could
debug it by print the
hashcode of getSession() in the page.

Hello,
I have a strange problem with StatelessForms in combination with login in:
On my MainPage are two stateless forms. One for registration and one for the
login (registration isn't implemented yet). When I try to log in, Wicket
creates a new User() and saves it in the Session (I made this like it's
explained in Wicket in Action). A System.out.print(user created) in the
constructor of User confirms that. Everything seems to be ok. But when the
main page reloads, I am still logged out.
And: When I change from StatelessForm to Form, everything works perfectly.
Something else might be important: When I request a page that requries
authorization and I'm not logged in, i'm being redirected to /login. There
is the same LoginPanel (with StatelessForm) as on the main page - and the
login works! But when I directly open /login it's the same as on the main
page and I can't login.
I also noticed that the login works (with StatelessForm) when I open a page
that requires authorization, then press the back button (back to main page)
and there try to log in.
The question is now, what am I doing worng? I can't find the problem in my
code, I have been trying a lot to find out what's worng but everything seems
to be correct. I couldn't find anything in the mailing list / on the web, I

This change prevents IChoiceRenderer#getIdValue() being called with -1

I assume you are using a custom IChoiceRenderer which doesn't use the

Try overriding #getModelValue():
@Override

final Foo object = getModelObject();

Re: ListView not refreshed after a new row is inserted with EJB3 as its backend data
Use a LoadableDetachableModelListUser in the ListView Constructor.
Put all the load loading into the load method and see what happens.

Hello, Everyone,
I am trying to build a web app with Wicket, EJB3, and MySQL. My IDE is
Netbeans 6.9.1 and the server is Glassfish 3.1.
I have created two entity beans 'Centre' and 'User', and one Centre has many
User(s). I also created two Facades for them.
The Wicket page used to list the Users is as below:
class ListUsers extends WebPage {
@EJB(name = UserFacade)
private UserFacade userFacade;
public ListUsers(Centre c) {
ListUser users;
if (c == null) {
users = userFacade.findAll();
} else {
users = new ArrayListUser(c.getUserCollection());
}
final ListViewUser list = new ListViewUser(eachUser, users) {
@Override
protected void populateItem(ListItem item) {
final User user = (User) item.getModelObject();
item.add(new Label(username, user.getUsername()));
item.add(new Label(fullname, user.getFullname()));
item.add(new Label(email, user.getEmail()));
item.add(new Label(centreid, user.getCentre().getName()));
}
};
add(list);
}
}
-
The page to add a User is following:
public AddUser(Centre c) {
user = new User();
user.setCentre(c);
FormAddUser form = new FormAddUser(AddUser) {
@Override
protected void onSubmit() {
userFacade.create(user);
}
};
form.add(new TextFieldString(username,
new PropertyModel(user, username)).setRequired(true));
PasswordTextField tf_password = new PasswordTextField(password,
new PropertyModel(user, hashedPassword));
form.add(tf_password);
form.add(new TextFieldString(fullname,
new PropertyModel(user, fullname)).setRequired(true));
TextField tf_email = new TextFieldString(email,
new PropertyModel(user, email));
form.add(tf_email);
LoadableDetachableModel centres = new LoadableDetachableModel() {
@Override
protected Object load() {
return centreFacade.findAll();
}
};
DropDownChoiceCentre ddc = new DropDownChoiceCentre(centreid,
new PropertyModelCentre(user, centre), centres,
new ChoiceRendererCentre(name, name));
form.add(ddc.setRequired(true));
add(form);
}
}
The problem is I can't see the newly added User in the list with
getUserCollection() method of Centre, but I do see the new User if I use
userFacade.findAll() method. Could you please help me and point me to the
right direction? I am quite new to Wicket and EJB3. Any comments are welcom.
Thanks a lot.

Re: how to get https port number in Wicket 1.5
Thanks for testing this out. I wasn't aware of that. I didn't understand the usecase exactly. You want to set the page / request secure if you've added the login form? Or do you want to secure the form only. For the later a possible answer is this http://stackoverflow.com/questions/96164/partial-site-ssl-using-asp-net-login-control It's a .net answer but the issue seems to be the same. Per Am 15.01.2012 01:41, schrieb armhold: Hi Per, The documentation for @RequireHttps implies that it only works for pages, not components, and my (limited) testing shows that to be the case. Is there a way to use it with components on otherwise insecure pages? My use case is to secure a form on non-https pages, specifically to secure that very nice username/password field at the top of Twitter Bootstrap pages.

Re: how to get https port number in Wicket 1.5
Stupid question. Is @RequireHttps at Form class working?

Assuming that the http/https port number have been set in WicketApplication

obvious solution is something like:
public class WicketApplication {
public int getHttpPort() { return 8080; }
public int getHttpsPort() { return 8443; }
public void init () {
// ...
setRootRequestMapper(new
HttpsMapper(getRootRequestMapper(), new HttpsConfig(getHttpPort(),
getHttpsPort(;
}
}
And then in my components:
((WicketApplication) getApplication()).getHttpsPort();
But I am wondering if there is a cleaner way to get this information,
perhaps from the RequestCycle.
Why am I asking? I'd like to create a Form subclass that always uses https.
Thanks
