WICKET-2213: At the very beginning of Wicket we introduced FormComponent.setPersistence() with the idea to make creating Login panels very easy. Basically Wicket would deal with the Cookie handling for the login details. Now some years later it is evident that this feature is not very useful:
- It basically is used for login panels only
- Even in our examples Password.setPersistence is false which means that "rememberMe" doesn't really work. Only the user name is stored in a Cookie
- Forcing formComponent.getPageRelativePath() as the Cookie name is too restrictive
- You can not combine username and password into a single Cookie and e.g. decrypt it for safety reasons
So we removed that feature and introduced IAuthenticationStrategy. A default implementation has been provided and the examples have been updated. As usual it gets registered with ISecuritySettings.

StringResourceModel#setLocalizer() was removed, if needed you can override #getLocalizer() instead.

AbstractSingleSelectChoice now uses an empty String instead of NO_SELECTION_VALUE ("-1"), allowing negative values for choices. See WICKET-933.
AbstractChoice.setType() now throws an UnsupportedOperationException as type-conversion is performed by the assigned IChoiceRenderer. See WICKET-3745.
Component rendering
We used to have different entry points to render a Page, a Component for a web request and a Component for an AJAX request. That is history. Whenever you want to render a component, simply call component.render().
...
- ITab.getPanel() now returns WebMarkupContainerWithAssociatedMarkup instead of Panel so it is now possible to create tabs using Fragments or Panels rather then just Panels.
- TabbedPanel.setSelectedTab() is now chainable
- TabbedPanel now takes a List<? extends ITab> rather then List<ITab>
Wizard
- Wizard no longer invokes IWizardStep#init(IWizardModel), this is now the responsibility of the IWizardModel itself. WizardModel and DynamicWizardModel do it already, but you have to take care of this for yourself if you have a custom IWizardModel implementation.
MarkupContainer.isTransparentResolver() removed

Page mounting
In 1.4 a custom IRequestCycleProcessor is needed:.x the parameters of mounted pages where encoded in the path of the URL by default:
Code Block |
---|
public class MyApplication extends WebApplication { @Override protected IRequestCycleProcessor newRequestCycleProcessor() { return new HttpsRequestCycleProcessor(new HttpsConfig()); } } http://server/mount/path/parameter1/value1/parameter2/value2 |
But now pages are mounted with MountedMapper instead, which leads to the following URLs:
Code Block |
---|
http://server/mount/path?parameter1=value1¶meter2=value2
|
To get the previous 1.4.x URLs you have to configure the mapper with a UrlPathPageParametersEncoder:
Code Block |
---|
mount(new MountedMapper("/mount/path", MyPage.class,
new UrlPathPageParametersEncoder()));
|
See Request mapping#MountedMapper for further mount options.
Switching to/from secured communication over https
In 1.4 a custom IRequestCycleProcessor is neededIn 1.5 this is re-implemented with the new HttpsMapper:
Code Block |
---|
public class MyApplication extends WebApplication { @Override publicprotected voidIRequestCycleProcessor initnewRequestCycleProcessor() { return new HttpsRequestCycleProcessor(new HttpsConfig()); } } |
In 1.5 this is re-implemented with the new HttpsMapper:
Code Block |
---|
public class MyApplication extends WebApplication { @Override public void init() { super.init(); super.init(); setRootRequestMapper(new HttpsMapper(getRootRequestMapper(), new HttpsConfig())); } } |
...
In Wicket 1.4 it was needed to extend org.apache.wicket.RequestCycle.onRuntimeException(Page, RuntimeException).
Wicket 1.5 gives even better control:
- add your own org.apache.wicket.request.cycle.IRequestCycleListener (AbstractRequestCycleListener) with org.apache.wicket.Application.getRequestCycleListeners().add() and implement its #onException(RequestCycle, Exception)
- or override org.apache.wicket.Application.getExceptionMapperProvider() - the IExceptionMapper is used if none of the configured IRequestCycleListeners doesn't know how to handle the exception.
For information on how the request cycle handles exceptions see RequestCycle in Wicket 1.5 for more information
ImageMap removed
ImageMap was deprecated in 1.4.11 and in 1.5 it was replaced with ClientSideImageMap component

And do something like this:
...
In case the markup file contains an xml decl such as <?xml version="1.0" encoding="utf-8" ?>
, it'll only be used for properly reading the markup. It'll never be used for the response and it's presence or absence will no longer determine whether an xml decl gets added to the response or not.
The response encoding is determined via Application.getRequestSettings().getResponseRequestEncoding()
and applies for all your pages.
WebPage.renderXmlDecl(response) and WebApplication.renderXmlDecl(response) have been introduced to control the xml decl contribution. The behavior can be changed per Page or for your whole application. It can generally be enabled, disabled or determined via a rule. The rule currently is simple: if the page mime-type is application/xhtml+xml
and the HTTP_ACCEPT header allows for the same, then insert the xml decl.decl.
Redirect to non wicket or external page.
Now when you need to redirect to a non Wicket managed URL or external link you can use RedirectRequestHandler instead of
Old code
Code Block |
---|
getRequestCycle().setRequestTarget(new RedirectRequestTarget("/usage.html"));
// or
page.getRequestCycle().setRequestTarget(new RedirectRequestTarget("http://www.facebook.com/"));

And post 1.5 version:
Code Block |
---|
getRequestCycle().scheduleRequestHandlerAfterCurrent(new RedirectRequestHandler("/usage.html"));
// or
page.getRequestCycle().scheduleRequestHandlerAfterCurrent(new RedirectRequestHandler("http://www.facebook.com/"));
