Re: Closing of tags
I get an ugly error message in the Safari Web Inspector saying "Unmatched
encountered. Ignoring tag"
Not sure why it flags it up as an error as I'm using the XHTML 1.0 Transitional
DTD and the closing tag must be valid, I'd just rather use the shorthand for
neatness.

Re: HttpsRequestCycleProcessor not immediately redirecting to https
Apologies, I now see it's exactly the same problem as described here:
http://old.nabble.com/%40RequireHttps---forms-misbehaving-ts26845496.html
I can reproduce this in a quickstart, I just want to check before creating a
jira:
- In my quickstart I'm calling setRedirect(true) within the form submit
button's onSubmit(), is this the correct place to force a redirect?
- SignInPage has the @RequireHttps annotation, *should* the code below result
in immediate redirection to the https page or am I missing something?
Button submitButton = new Button("submit") {
@Override
public void onSubmit() {
setRedirect(true);
setResponsePage(new SignInPage());
}
};

HttpsRequestCycleProcessor not immediately redirecting to https
As part of a product purchase workflow I require users to sign-in or register a
new account in order to continue.
In my purchase page I'm checking if the user is already signed-in and if not I
send them to a SignInOrRegisterPage which has the @RequireHttps annotation.
BookingPage dest = new BookingPage(product);
if (signedIn) {
setResponsePage(dest);
} else {
session.getDefaultPageMap().put(dest);
PageReference destPageRef = dest.getPageReference();
setResponsePage(new SignInOrRegisterPage(destPageRef));
}
@RequireHttps
public class SignInOrRegisterPage extends StandardBasePage {
private PageReference destination;
public SignInOrRegisterPage(PageReference finalDest) {
..
In MyApplication:
@Override
protected IRequestCycleProcessor newRequestCycleProcessor() {
HttpsConfig config = new HttpsConfig(MyApplication.get().getHttpPort(),
MyApplication.get().getHttpsPort());
return new HttpsRequestCycleProcessor(config) {
@Override
protected IRequestCodingStrategy newRequestCodingStrategy() {
return new CryptedUrlWebRequestCodingStrategy(new
WebRequestCodingStrategy());
}
};
}
The initial redirection to SignInOrRegisterPage does not go to https, only when
I submit the form on the http SignInOrRegisterPage does it then redirect to
https.
Any ideas why it's not going immediately to https?
Thanks

Redirect to bookmarkable page from self - broken in 1.4.6?
I've mounted a bookmarkable page as follows:
mount(new IndexedParamUrlCodingStrategy("destinations",
DestinationGuidePage.class));
Then I've got a drop-down menu with an ajax behaviour to redirect to the same
page with different parameters:
destinationChoice.add(new AjaxFormComponentUpdatingBehavior("onchange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
onUpdateSelection(target);
}
});
protected void onUpdateSelection(AjaxRequestTarget target) {
PageParameters params = new PageParameters("0=" +
selectedCountry.getId());
setResponsePage(DestinationGuidePage.class, params);
}
In 1.4.5 this works fine and the relative redirect is ../destinations/
DEBUG org.apache.wicket.Page - ending request for page [Page class =
com.myapp.webapp.destguide.DestinationGuidePage, id = 3, version = 0], request
[method = POST, protocol = HTTP/1.1, requestURL =

/URC107/, pathTranslated = null]
DEBUG org.apache.wicket.protocol.http.WebResponse - Redirecting to

This no longer works in 1.4.6 as it redirects to "destinations/"
which results in the full URL /myapp/URC107/destinations/destinations/

I can't see any indications in the 1.4.6 release notes to say this behaviour
may have changed, is this a bug?

IndexedSharedResourceCodingStrategy - shared resource not found
I'm mounting a shared resource with
IndexedSharedResourceCodingStrategy and in my Application class I've
got:
init() {
...
// DynamicCss extends DynamicWebResource
Resource dynamicCssResource = new DynamicCss();
getSharedResources().add("dynCss", dynamicCssResource);
mount(new IndexedSharedResourceCodingStrategy("style", "dynCss"));
...
}
I can access the shared resource fine if I obtain it via the
ResourceReference constructor e.g. in Page -
add(CSSPackageResource.getHeaderContribution(new
ResourceReference("dynCss"), "screen"));
But if I try to access the resource via the mount point I get the
following error in the logs:
http:///context path>/style
o.a.wicket.request.target.resource.SharedResourceRequestTarget -
shared resource dynCss not found or not allowed access
Is this a bug in IndexedSharedResourceCodingStrategy or am I missing
something?
Any suggestions much appreciated.

Re: Prefix URL for skinnable site

Re: validation message-keys differences on m3 to rc2
ComponentStringResourceLoader's javadoc is very helpful here: assume a component hierarchy like page1.form1.input1 and your are requesting a key named 'Required'. Wicket will search the property in the following order: page1.properties => form1.input1.Required page1.properties => Required form1.properties => input1.Required form1.properties => Required input1.properties => Required myApplication.properties => page1.form1.input1.Required myApplication.properties => Required What it doesn't mention is that if the form component is nested in another container such as a border then the border id needs to be included in the key. e.g. if I have page1.form1.border1.input1 then in the form's properties file I have to include the border component in the key - border1.input1.Required, it would be cleaner just to be able to use input1.Required. -Gianni On 18/mar/09, at 21:09, Gianni Doe wrote: https://issues.apache.org/jira/browse/WICKET-2159 On 10/mar/09, at 15:55, Igor Vaynberg wrote: jira, quickstart, you know the drill -igor On Tue, Mar 10, 2009 at 3:15 AM, gilberthuph wrote: I'm having exactly the same problem after moving from 1.4-rc1 -> 1.4-rc2 Here's the extract from my properties file TaxiBookingPage.xml. http://java.sun.com/dtd/ properties.dtd"> key="generalDetails.numberOfVehiclesRequired.Required">You must enter the number of vehicles .. snip ..

FormComponentPanel and specifying tabindex for form input
I've got a custom date picker component that extends FormComponentPanel and I include it in my markup with. [date picker] The component uses a hidden form field to store an ISO formatted date value and a display field to show the localised full date. It's the hidden field that is used as the component model. I'd like to somehow be able to specify the tabindex attribute for the date display field in the page markup, so that this can be controlled by the page designer. I tried setting a tabindex attribute on the with the intention of removing it and then setting it on the date field, but the attribute is immutable and can't be removed from the . Any ideas?

Custom validator variablesMap() - Value of variable [[input]] could not be resolved
Hi
I've written a custom validator and error message and I'm adding my
own variables to the error message by overriding variablesMap().
My error message looks like thie:
${input} must be between
${startDate} and ${endDate}
As I understand 3 default variables should be substituted by the
validator for ${label} ${input} and ${name}; if I use ${label} and $
{name} they get substituted fine but ${input} is not:
WicketMessage: Exception 'java.lang.IllegalArgumentException: Value of

{input} must be between ${startDate} and ${endDate}]]' occurred during
validation com.resprompt.webapp.validation.LocalDateTimeValidator
$LocalDateTimeRangeValidator on component
0:carHireSearchForm:dropoffDate
I've had a look through the source for the Wicket built-in validators
and I can't seem any instance of 'input' being added explicitly to the
variablesMap, any ideas why this isn't being set for me?
public abstract class LocalDateTimeValidator

Add AJAX behaviour to embedded custom form component
I've developed a custom form component (FormComponentPanel), a date
picker, that makes use of 2 fields - a display TextField and a
HiddenField for the model data. I'm then adding this to the page with
a span tag:
[dropoff date picker]
Then in the java :
DatePicker dropoffDatePicker = new DatePicker("dropoffDate", new
PropertyModel(this, "dropoffDate"),
(new LocalDate()).minusDays(0), (new
LocalDate()).plusYears(3));
I'm after some advice on the best way to attach an AJAX behaviour to
the component. If for example I add an AJAX behaviour directly to the
date picker component then it's attached to the span tag and obviously
doesn't work. The only way I've found to get around this is to expose
the date display field with a public getter so I can then attach the
onchange event.
dropoffDatePicker.getDateDisplayField().add(new
AjaxFormComponentUpdatingBehavior("onchange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
..
}
});
Any suggestions for a better way to do this that doesn't involve
exposing the innards?

Re: LoadableDetachableModel for drop-down menu selection
Thanks Igor, I've already got my entity model LoadableRefDataModel
which is similar to your example and I can see how to make use of this
when I've actually got the entity object or id. My problem is I'm not
clear on how I go about creating the entity model when a value is
selected from my drop-down menu.
private Country selectedCountry;
countryChoice = new DropDownChoice(
"country", selectedCountry, countryModel,
countryRenderer);
In the above example selectedCountry is populated when a value is
selected from the drop-down, what I'd like to do is replace
selectedCountry with a LoadableDetachableModel.
i.e.
private LoadableRefDataModel country;
But I can't work out where to put the instantiation code. Is there
some method of DropDownChoice I can override to do this or would I
wrap my entity model in another model, overriding setObject() to
instantiate my entity model.
What would be the recommended way?

but I'm not clear on where and how I should instantiate it.
i.e. for the example below where do I put the "new
LoadableRefDataModel(selectedCountry);".
I'd appreciate some suggestions, I think I'm getting the hang of the
Model idea but can't see the wood for the trees at the moment.
public class LocationSearchPage extends WebPage {
private DropDownChoice countryChoice;
private DropDownChoice locationChoice;
private Country selectedCountry;
private List locations = new ArrayList();
private Location selectedLocation;
@SpringBean
private RefDataService refDataService;
public LocationSearchPage() {
Form searchForm = new Form("searchForm") {
@Override
protected void onSubmit() {
//...
}
};
add(searchForm);
ChoiceRenderer countryRenderer = new
ChoiceRenderer("description", "id");
IModel> countryModel = new
LoadableDetachableModel>() {
@Override
protected List load() {
return refDataService.getCountries();
}
};
countryChoice = new DropDownChoice(
"country", selectedCountry, countryModel,
countryRenderer);
countryChoice.add(new
AjaxFormComponentUpdatingBehavior("onchange") {
protected void onUpdate(AjaxRequestTarget target) {
this.selectedLocation = null;
locationChoice.setChoices(new
ArrayList(selectedCountry.getLocations()));
target.addComponent(locationChoice);
}
});
ChoiceRenderer locationRenderer = new
ChoiceRenderer("description", "id");
locationChoice = new DropDownChoice(
"location", new PropertyModel(this,
"selectedLocation"), locations, locationRenderer);
}
}
public class LoadableRefDataModel extends
LoadableDetachableModel {
@SpringBean
private RefDataService refDataService;
private Class type;
private Serializable id;
public LoadableRefDataModel(Class type, Serializable id) {
InjectorHolder.getInjector().inject(this);
this.type = type;
this.id = id;
}
public LoadableRefDataModel(T domainObject) {
super(domainObject);
InjectorHolder.getInjector().inject(this);
this.type = (Class) domainObject.getClass();
this.id = domainObject.getCode();
}
@Override
protected T load() {
return refDataService.load(type, id);
}
}

ContextImage not generating path relative to context root
I'm a bit confused about ContextImage; according to the javadocs the
image path "will be prefixed such that the image is relative to the
context root".
In my markup I've got:
Then I add the Context image to my WebPage:
add(new ContextImage("logo", "images/logos/mylogo.gif"));
... and I end up with:
My application is deployed with a context root of /myapp and this
doesn't work, it will only work if the application is deployed with a
context root of /. I've checked the source which ContextImage uses to
get the context root and in org.apache.wicket.Request it says:
/**
* Gets a prefix to make this relative to the context root.
*
* For example, if your context root is http://server.com/myApp/ and
the request is for
* /myApp/mountedPage/, then the prefix returned might be "../../".
*
* For a particular technology, this might return either an absolute
prefix or a relative one.
*
* @return Prefix relative to this request required to back up to
context root.
*/
public abstract String getRelativePathPrefixToContextRoot();
To me this just seems plain wrong, here it clearly states that the
context root is "http://server.com/myApp/"; but the example prefix of
"../../" relative to "/myApp/mountedPage/" does not take you to the
context root of /myApp/ but to /.
This is very confusing as I've always considered the context root of a
java web application to to be the path upon which it is deployed on
the application server, whether that be /, /myApp or /apps/myApp and
in the above case I do not end up with an image path relative to the
context root.
Without hard-coding the name of my context root in the image path (bad
idea for portability) how can I reference static images stored in an
images directory under the context root?
Should I file this as a bug or am I missing something?
Thanks
Gianni
