The code above creates context-absolute url.

I'd suggest to rework it to:
String relativeUrl = urlFor(new PackageResourceReference(Anchor.class,
LOGO_NAME), pp);
String fullUrl =
requestCycle.getUrlRenderer().renderFullUrl(Url.parse(relativeUrl));

But usage of full url is not recommended when your application runs behind
proxy server.

RE: Page's Mounted URL

[Colin Rogers]

I did! But as I said - urlFor() only deals in relative paths.

So if I'm on page X and ask for the path of X I always get "./" which isn't 
useful for determining anything! :)

(and using getUrl() of the request gives me the ajax URL for the link I just 
requested - " ?2-3.ILinkListener-settings-myLink")

I'm using something like the following (in 6.7.0):

String url2 = RequestCycle.get().getUrlRenderer()
.renderFullUrl( Url.parse(urlFor(Page.class, newPps).toString()));

Hi,

On 01/05/2013 10:57 PM, smallufo wrote:

String url2 = RequestUtils.toAbsolutePath(urlFor(Page.class ,
newPps).toString() , "");
System.out.println("url2 = " + url2); // full in 1.4 , but relative in 6.0
The Javadoc says "Calculates absolute path to url relative to another 
absolute url." so that's expected.

It means , if I need to get full url (including host / context-path) , I
have to write :
*String fullUrl =
getRequestCycle().getUrlRenderer().renderFullUrl(Url.parse(getRequestCycle().urlFor(new
RenderPageRequestHandler(new PageProvider(Page.class , newPps);*

It is so lengthy and cumbersome . Is there any shortcut for this ?
That's what I use, but I wrapped it in a public static util method 
somewhere...

Re: even issue switching from development to deployment mode

[Bertrand Guay-Paquet]

Hi,

I believe Wicket uses a minified version of jQuery in deployment. Maybe 
this causes problems with that library?


Otherwise, check all callers to Application#usesDevelopmentConfig() and 
replace them one by one to the deployment value until you get the same 
error.

Any thoughts on this please, what is different in wicket between deployment

Resource Path

[Hemen]

I have an image that I access by using the following code:

String fullUrl = (String) "/" + RequestCycle.get().mapUrlFor(new
PackageResourceReference(Anchor.class, LOGO_NAME), pp).toString();

Logo path on my dev ==>
http://host-name/wicket/resource/package.Name.ClassName/logo.png
Resource Path on Test ==>
http://host-name/app-ame/wicket/resource/package.Name.ClassName/logo.png

The logo get displayed on my dev but when deployed on test, it appends the
/app-name/ and wicket fails to find it. 

Here is the build config inside pom.xml for the project 


app-name


src/main/resources


src/main/java

**


**/*.java




How can I correct this? 

Thank you

Hemen

What's a simple substitute for CancelEventIfNoAjaxDecorator in Wicket 6.x

[Paul Bors]

 

I'm migrating from 5.x to 6.x and I have a few classes that make use of the
older IAjaxCallDecorator and I was wondering what's a simple substitution
for code like this:

 

add(new AjaxEventBehavior("onclick") {

  protected void onEvent(AjaxRequestTarget target) {

ISortState state = stateLocator.getSortState();

  if (!defaultSortAsc && state.getPropertySortOrder(property) ==
SortOrder.NONE ) {

state.setPropertySortOrder(property, SortOrder.ASCENDING);

  }

  onClick();

  onAjaxClick(target);

  }

  protected IAjaxCallDecorator getAjaxCallDecorator() {

return new CancelEventIfNoAjaxDecorator(decorator);

  }

});

 

I have this for my own AjaxFallbackOrderByBorder I use for the sortable
headers in most of the table.

Re: Disabling Individual Checkboxes in CheckGroup

[Paul Bors]

See the examples for form input and the use of CheckGroup:
http://www.wicket-library.com/wicket-examples/forminput

If you want to "uncheck" or "check" one of your component, either insert or
remove from your collection the element you want checked or not.

~ Thank you,
   Paul Bors
PS: If by now you haven't put together a quick start for yourself to
understand how CheckGroup works in Wicket, then I suggest you do so.

Re: file listing in the browser

[Paul Bors]

No one replie to you because this has nothing to do with Wicket.

You might want to get familiar with Java's File IO:
http://docs.oracle.com/javase/tutorial/essential/io/walk.html

Once you get to iterate over your folder you may choose to show that in
Wicket via a repeater or a data table etc.
For that you can look up the Wicket examples at:
http://www.wicket-library.com/wicket-examples/ajax/tree/simple;jsessionid=E02464D70A1FD689C3E20641746C002E?0

Good luck!

Wicket-Bootstrap error when deploying to JBoss AS 7

[David Beer]

Hi All

I have a web project which uses Wicket-Bootstrap for styling and various 
other functions. Everything appears to run fine in Tomcat, but I am 
starting to add more Java EE stuff and looking at using JBoss As 7. I 
can deploy a normal wicket Quickstart with out errors but when I try and 
deploy a project with Bootstrap added I get the following error:

even issue switching from development to deployment mode

[saty]

I am using JQuery multi select by Eric Hynds in my current wicket application
in few places.
http://www.erichynds.com/examples/jquery-ui-multiselect-widget/demos/

This works great in a Wicket application (using ListMultipleChoice) in
wicket development mode,  but when i change wicket mode to deployment
surprisingly the onclose even (close multiselect) does not get fired, the
onchange event (when you select/deselect) continue to work, no issues with
that.

Any thoughts on what might be going on here and how to fix this problem,
within Wicket.

Appreciate your help.

Thanks

How to get rid of -ver-blah-blah-blah.gif versioning ?

[smallufo]

I am upgrading from 1.4 to 6.7

I try to redeploy and the appended string is identical !?

Now I am stuck by how to get rid of image/resource versioning , and enable
caching ...
I use general Image ,
or override shouldAddAntiCacheParameter (return false)
But I still cannot get rid of the versioning string...

Anyway to disable that ?

Re: Get data from External application.

[chrome1235]

Bertrand thanks for your quick reply.

I will call it from a page (incluedes form and fields). then returned value
fill a form text element. lastly user submit all values.

If I can not succeed by this method, I will do with your suggestion.

Assuming you want to mount this under the "activate" path.

I just noticed your example uses the root app mount. I think you might 
run into some problems with mappers if you use a path like "/#{code}" 
instead. Incoming requests for other pages could be confused with the 
ones for barcodes.

Hi,

Sure you can!

In BarcodePage, use the PageParameters to extract the code. If the code 
is there, show its associated content.

StringValue codeValue = getPageParameters().get("code");
if (!codeValue.isEmpty())
...

In your app init code, mount your page like this:
mountPage("/activate/#{code}", BarcodePage.class);

Localized urls

[Bertrand Guay-Paquet]

Hello,

I'd like to localize the urls generated by my app like so:
/en/account/settings   -> AccountSettingsPage, locale EN
/fr/compte/parametres   -> AccountSettingsPage, locale FR

I already have urls prefixed with the locale base on the 
LocaleFirstMapper from Wicket examples, but they are all mapped the same 
way after the locale segment, like this:

/en/account/settings
/fr/account/settings

I could think of 2 potential approached to this, but neither seem easy 
to implement...


1- In my LocaleFirstMapper, have one "set" of localized mappers for each 
locale. I would need to duplicate the built-in mappers (link listeners, 
forms, etc.) manually for the extra sets of mappers.


2-Create a new RequestMapper class based on MountedMapper which allows 
custom dynamic parts in urls, somewhat like the page parameter 
placeholders make a url dynamic.


Any ideas or comments? Has anybody done this before?

Thanks!
Bertrand

Re: Question regarding exceptions in Apache Wicket

[Behrooz Nobakht]

Thanks for the reply.

The purpose is that when it's determined that exception comes from Wicket,
the error page (1) can reduce the cause chain (which can be independent of
Apache Wicket of course), and (2) based on this information provide the
user to report a bug or email the stack trace to a set of stack holders.
That's why I was thinking using "instanceof" as less as possible is more
preferred and indeed cleaner instead of checking "package names".

I generally agree that this could be done independent of how Apache Wicket
exceptions are designed and it's more categorized in the "convenience"
zone.

for what purpose? an unhandled exception is an unhandled exception...

because we could not come up with a good usecase for having a common
parent. in any case there would have to be two parents - one for
checked and one for unchecked exceptins. which means that both would
have to implement some kind of a tagging interface to allow a single
instanceof check. but without a valid usecase why do this?

if you really want to know you can see if the exception class lives in
the org.apache.wicket.* package, and if it does its a wicket
exception.

Re: Question regarding exceptions in Apache Wicket

[Behrooz Nobakht]

More clearly, the intention is to be able to distinguish exceptions from
Apache Wicket and other frameworks and not really handle them. For
instance, there can be two exceptions: MarkupException and
CouldNotLockPageException. Both are in the context of Apache Wicket,
however, we actually need to "two" checks to determine either. If they
inherited a common parent class, it needed "one" check.

I do not want to say that Apache Wicket should have done this. I first want
to understand why this design decision has been made.

Re: Question regarding exceptions in Apache Wicket

[Igor Vaynberg]

what is the purpose of knowing whether an exception is a wicket
exception or something from further down the stack?

eg how would you handle a runtime exception that came from within
java.lang.String differently then the one that came from Wicket or the
one that came from the servlet api?

Question regarding exceptions in Apache Wicket

[Behrooz Nobakht]

Hello,

I've been working on an error page in Apache Wicket and came across a
general pattern in Apache Wicket and I'd like to understand the reason for
it.

Exceptions in Apache Wicket do not have a single class hierarchy; i.e.
there are exceptions that eventually extend "WicketRuntimeException" but
they are also many others that start either from "RuntimeException" or
"Exception". I could guess for the reasons for "checked" exceptions but why
 did *not* Apache Wicket introduce exception classes that all inherit from
a single exception class?

A direct side effect of this design decision is that the check (e
instanceof WicketRuntimeException) cannot give an indication if the
exception is actually an exception raised by Wicket and need separate
checks for different concerns.

Thanks in advance for your explanations.

Regards,
Behrooz
