Wicket pages are stateless by default. It is just that it is very easy to
become stateful.

Or set a fresh instance as a model object of the Form.

Hi,

You can use Wicket Events -

Andrea - thanks, but how can I access the panels from a child panel within the 
component hierarchy of a page without having to put them in the constructor of 
each child panel?

Re: Empty form values after successful onSubmit?

[Sven Meier]

Hi,

I don't think you're doing something weird, you're just seeing the 
normal Wicket behavior:


>I debugged a bit

Good!

>that "success" calls though to some logic which marks my page as dirty
>generated a new version number, stores the changed page in the session

All pretty normal.

>I don't see anything to interfere with that

Why should you?

> the ctor of my page is not called again
> the same with onInitialization

Why should it?

Wicket is stateful by default, so it will keep the current page as long 
as the user doesn't navigate away from it.


After form processing the input of all form components are cleared, but 
after that you see the model values instead.
You can navigate to a new page instance 
(#setResponsePage(this.getClass()) if you want to start over with empty 
input *and* an empty model.

Sven

Re: swap panels from child element

[Sven Meier]

Hi,

replacing is really easy:

  this.addOrReplace(panel);

... as long as all your panels have an identical Wicket id.

I often prefer this approach over changing visibility because of smaller 
session size (i.e. not keeping unused panels in the component tree) and 
simpler markup (i.e. not requiring a  for each panel).


Your mileage may vary.

Sven

I debugged a bit and can verify that "success" calls though to some
logic which marks my page as dirty, generated a new version number,
stores the changed page in the session and such. I don't see anything

I do see the success message AND the values of the input which have

So, you tell me that I'm doing something wrong? I only have a form and
use it as a compound one as the default model. Any ideas on where I
should look at to find the problem?

Re: Wicket JQuery Selectable Sortable combined

[Sebastien]

Hi Chris,

You're welcome!

The list is already the Sortable's model object, if you are able to send
the item hash, you are able to retrieve the item, then you just have to
invoke
Sortable#onRemove(target, item) [1] and this should be all fine...

Hope this helps,
Sebastien.

Re: put Javascript in HTML body

[Chris]

Hi Martin, Shengche,

thanks a lot!

I used the approach as explained in 
http://wicket.apache.org/guide/guide/resources.html#resources_7 
 by providing 
a custom IHeaderResponseDecorator and using the Wicket container tag. Then I 
used the OnDomReadyHeaderItem.forScript() method to include the specific 
JavaScript code:
@Override
public void renderHead(IHeaderResponse response) {
response.render(OnDomReadyHeaderItem.forScript();
}
Because of the HeaderResponseDecorator set in the init method of the 
application, the JS-code of all pages will be placed in the body. 

How can I adapt this method, so that by default, all JS-code is placed in the 
header, and only that of a certain page is put in the body tag?

Thanks, Chris

Hi Sebastien,


thanks a lot for your example, it works fine!
One question remains: how is it possible to add the ListModel as Ajax target so 
that when I delete a selected element, the displayed elements are updated? 

@Override
public void onSelect(AjaxRequestTarget target, List items) {

Re: Plans for further wicket classes with generics

[Martin Grigorov]

Hi,

There is a discussion about this since Wicket 1.4 (the first version of
Wicket built against JDK 1.5).
The main stopper is that using generics makes the code even more verbose.
And many people don't like this.
So there are few Generic*** versions of the most used components.

Plans for further wicket classes with generics

Hi,

Already in Wicket there is GenericPanel, GenericWebPage,
GenericFragment, IGenericComponent, and IModel of course is already
generic.

But there is still IBehavior without Generics and several standard
components which do not implement IGenericComponent such a Label.

Are there plans to further promote APIs with generics, also maybe
deprecating the APIs which do not use generics (classes Panel, Page,
etc.)?

Or is there a good reason not to use Generics?

Re: Having Wicket manage resources outside classpath

[Tobias Soloschenko]

It would be good to change the Wicket implementation here so that several 
ICssCompressor could be added. With an ArrayList for example - then you could 
add a css compressor to the beginning of the chain with 
getCssCompressors().add(0,myCoolNewCssCompressor)

Re: Having Wicket manage resources outside classpath

[Martin Grigorov]

Additionally we used preloading of static resources.
At app start time (i.e. MyApp#init()) we fired an artificial request to all
registered CSS/JS bundles. The response has been cached (by a
specialization of ConcatBundleResource) and later all real/runtime requests
were using the cache.
This way the compression (CSS & JS) has been done just once. By default
Wicket would do it for each request.

 We typically put our resources at the root of the context:
 /assets/css
 /assets/js
 /assets/images
 /WEB-INF/
 
 This way we can reference images from within our style sheets using
 'background:url(../images/logo.png);'

Hi Tobias,

I imagine it with a regex that parses for "url(...)" and replaces the old
url with a new one.

Re: Having Wicket manage resources outside classpath

Hi,

would be a good to see such an implementation out of the box. (CSSCompressor) 

I try to do it soon - maybe with a varags of URLs which are going to be passed 
into the CSS file.
