ahh ok change this
new ListView(list, new ArrayListMap.EntryIKey,Integer(map.entrySet()))
{

thats wrong you can't keep Map.Entry objects in a arraylist.
why not keep the map yourself?

new ListView(list, new Model(map) {

Maps are not serializable. Now I'm confused.

btw: I didn't make the variable final to use it in an inner class. It
was just a leftover of cp.

Re: [Wicket-user] 1.2.x trunk stack overflow


that seems to be a problem yes
what i did was change the Settigngs one:

contextPath =
((WebRequest)RequestCycle.get().getRequest()).getHttpServletRequest().getContextPath();

so that i directly call the context path of the http servlet request.

i think that should work fine, or does some have WebRequest.getContextPath()
overwritten so that they supply there something else??

I notice ServletWebRequest.getContextPath implmentaton changed:

in 1.2.6:
public String getContextPath()

}

in 1.2.x trunk
public String getContextPath()
{
String contextPath = Application.get
().getApplicationSettings().getContextPath();
return contextPath != null ? contextPath :
httpServletRequest.getContextPath ();
}

so the problem is caused by additional 
Application.get().getApplicationSettings().getContextPath();


I know wicket has a bamboo to build trunk continuously, but I can't find
it to check trunk's health.

this only works if you have a seperate method:

 if (orders == null)

 orders = DAO.getOrders()
 }
}

iterator()
{
  return getOrders().sublist(x,y).iterator()

size()

detach()
{
 orders = null;

I tried with customresourceloading from wicket-examples its working but the
problem is with markup cache.

I am having to different markups for the same page(java file) so when I
start my server and hit that page it with criteria that selects markup
dynamically it displays that page with that markup but when I hit it one
more time (without restarting server) with different criteria which should
change the markup but it is showing first(old or previous) markup. 
After doing google, I came across this markup cache thing. but didnt get any
solution.

Could you please suggest on this problem?

 Yep, see PageWithCustomLoading from that example. Also note that the
 application scoped setting is a strategy, so with a bit of thinking
 you can bend it every way you want it.

Re: [Wicket-user] Bug in 1.3? HeaderContributor.forCss(String)

2007-05-30 Thread Al Maw

Relative URLs are good - they make the page work properly behind proxy
servers. Why do you want an absolute one? Do your resources live in a
different context or something?

If you're trying to serve resources relative to your context root, just
add it with:
add(HeaderContributor.forCss(resources/styles/global.css));

And that should work just fine (generating a relative URL).

Arguably we should strip off the first / if you put in an absolute 
path, so this is more transparent to the end user. I'm not convinced 
that enough people want to serve their resources from a different 
context path that we should provide absolute URLs - they're obviously 
open to people using them then wondering why it's broke behind a mod_proxy.

Regards,

Al

 I consider this a bug, and was wondering if you do as well...  If so, I

 In my 1.2.6 app, I have the following line:
 add(HeaderContributor.forCss(/resources/styles/global.css));
 
 which generates this in the markup (correctly):
 link rel =stylesheet type=text/css href=/resources/css/global.css 
  /link
 
 
 In 1.3, it generates this in the markup (incorrectly):
 link rel =stylesheet type=text/css 
 href=../../..//resources/styles/global.css /link
 
 This is because of the change to have everything with relative URLs, I 
 am assuming.  But, I don't want a relative URL, I want an absolute one.  
 I'm thinking that the following change would be appropriate:
 
 HeaderContributor.java (26)
 if (location.startsWith(http://;) || location.startsWith(https://;))
 
 changed to:
 
 if (location.startsWith(http://;) || location.startsWith(https://;) || 
 location.startsWith(/))
 
 
 Thoughts?

[Wicket-user] [BUG]script tag evaluation in IE

2007-05-30 Thread Alex Objelean


Probably it is well known bug for most of you, but I think it worth to
mention again about it and its workaround. 

The bug appears when the ajax response contains a script which normally
should be evaluated (and it does in gecko browsers) but the script is not
evaluated in IE (any version, including IE7) I found two workarounds for
this issue:

1) Wrap the script into the form tag. But it has a drawback, you must be
careful to not have embedded forms. Not very convenient solution..

2) Wrap the script into the  tag, like this:


  script
//your script
  /script


The style=display:none is important because embed object itself should not
be visible, it is just a container which simply makes the script tag
evaluation work in IE...And this is the best choice to make it work in
XBrowser fashion.

Alex.

Re: [Wicket-user] Implementing a PopupPanel

2007-05-30 Thread John Krasnay

One way to solve the abstract method from the constructor problem (or
more precisely, the non-final method from the constructor problem) is
to use a Model, e.g...

public class PopupPanel extends Panel {
public abstract String getTitle();
public PopupPanel(String id) {
add(new Label(foo, new AbstractReadOnlyModel() {
public Object getObject(Component component) {
return getTitle();
}
}
}
}

The model's getObject is only called some time after the object has
been constructed.

Re: [Wicket-user] [Nuub] Best practise: Navigation Component

2007-05-30 Thread John Krasnay

One idea would be to create a class that represents the logical idea of
a link, e.g

public class NavEntry {
private String title;
private Class pageClass;
private PageParameters parameters;
...
}

Pass a list of these to the constructor of your panel, which then
renders these into actual links and labels.

If this is too restrictive, e.g. if you want different kinds of links,
not just BookmarkablePageLinks, you can defer creation of the link to
the NavEntry object:

public class NavEntry {
...
public abstract WebMarkupContainer createLink(String id);
}

public class BookmarkablePageNavEntry extends NavEntry {
private Class pageClass;
private PageParameters parameters;
public WebMarkupContainer createLink(String id) {
return new BookmarkablePageLink(pageClass, parameters);
}
}

A similar technique is used in the tabs package in wicket-extensions.

 Hi,
 
 I am new to Wicket and I really like the things I have seen so far. But 
 I also have a few questions.
 At the moment I create a small page. Therefore I have created a 
 NavigationComponent (extends Panel) with its own markup file and some 
 other resources (css, images).
 
 Can anybody describe me the best way to add Links (most of them are 
 BookmarkableLinks) and the corresponding Labels to this component?
 At the moment I create a List of Links. Each of those links has a Label 
 added. Those links are then provided to a DataView and given to the 
 NavigationComponent.
 I don't like this because I have to create the components manually 
 (Links and Labels) with the correct ids. What approach would a wicket 
 expert take?
 
 Later I might reuse the NavigationComponent within another application. 
 But therefore I would like to modify/replace the CSS and replace some 
 images. What is the Wicket way to achive this?
 
 
 Thanks in advance,

Re: [Wicket-user] Implementing a PopupPanel

2007-05-30 Thread Ravindra Wankar






Thanks John. I was suspecting no one to reply to a long mail.

Unfortunately, in my case the getTitle() returns a component not the
label text. The component returned by the child can either be a "label"
or an "image" component. The derived class gets the label text in its
constructor which it uses to construct the label but the parent calls
getTitle() too soon.

As there are 2 components within the parent (title and contents) that
the child needs to fill, I could not use markup inheritance.

Thanks,
Ravi.

  }
 
  in 1.2.x trunk
  public String getContextPath()
  {
  String contextPath = Application.get
  ().getApplicationSettings().getContextPath();
  return contextPath != null ? contextPath :
  httpServletRequest.getContextPath ();

  so the problem is caused by additional 
Application.get().getApplicationSettings().getContextPath();
 
 
  I know wicket has a bamboo to build trunk continuously, but I can't
  find it to check trunk's health.

[Wicket-user] Stable URLs (Was: Bookmarkable pages and transparent login)

2007-05-30 Thread Thomas Singer

OK, I've tried to create an unversioned page to keep the URL stable using 
following page code:

 public class DownloadFile extends TemplatePage {
 
   // Constants 
 ==
 
   private static final String FILE_PARAMETER = file;
 
   // Static 
 =
 
   public static BookmarkablePageLink createLinkToPage(String id, String 
 file) {
   final BookmarkablePageLink pageLink = new 
 BookmarkablePageLink(id, DownloadFile.class);
   pageLink.setParameter(FILE_PARAMETER, file);
   return pageLink;
   }
 
   // Setup 
 ==
 
   public DownloadFile(PageParameters parameters) {
   final String file = parameters.getString(FILE_PARAMETER);
   if (file == null) {
   throw new 
 RestartResponseAtInterceptPageException(Download.class);
   }
 
   if (!getOurSession().isLicenseAgreed()) {
   addContent(createLicenseFragment(contentPanel, 
 parameters));
   throw new RestartResponseAtInterceptPageException(this);
   }
 
   addContent(createDownloadFragment(contentPanel, file));
   }
 
   // Utils 
 ==
 
   private Fragment createDownloadFragment(String id, String file) {
   final Fragment fragment = new Fragment(id, downloadFragment);
   fragment.add(new Label(file, file));
   return fragment;
   }
 
   private Fragment createLicenseFragment(String id, final PageParameters 
 parameters) {
   final Fragment fragment = new Fragment(id, licenseFragment);
   fragment.add(new PageLink(accept, new IPageLink() {
   public Page getPage() {
   getOurSession().setLicenseAgreed(true);
   return new DownloadFile(parameters);
   }
 
   public Class getPageIdentity() {
   return DownloadFile.class;
   }
   }));
   return fragment;
   }
 
   public boolean isVersioned() {
   return false;
   }
 }

Every page is mounted with QueryStringUrlCodingStrategy. On the Download 
page a link to this DownloadFile page is created using the above 
createLinkToPage() static method call which creates a link to 
http://localhost:8080/smartcvs/download-file.html?file=win32jre;
Curiously, when I click on it, the browser displays 
http://localhost:8080/?wicket:interface=:2::; as URL. The accept-link 
occurs pointing to 
http://localhost:8080/?wicket:interface=:2:border:contentPanel:accept::ILinkListener;.
 
When I click it, the browser displays 
http://localhost:8080/?wicket:interface=:3::; as URL. Clicking the 
back-button shows the http://localhost:8080/?wicket:interface=:2::; page 
with the accept-link, no matter whether I try it with Opera or FireFox.

 Regarding the back-button: it would be the best if the intermediate license
 agreement page would not occur when pressing the back-button, but instead
 the previous page (if any). Is something like that possible?
 
 What you need to achieve is that the URL stays stable. One way to
 achieve this is to use panel replacement. E.g. when you click the
 download page, you replace the main panel on your page with a panel
 that displays the license agreement. If you turn off versioning for
 that page, the URL will stay stable and thus if you push the back
 button later, your browser will return to the first version of the
 page. I think this should work for most browsers (maybe only not with
 Opera). There are alternative ways to do this, including throwing
 RestartResponseExceptions, using custom page factories and custom url
 coding strategies. Or you can trick the browser using JavaScript, of
 which I don't know too many details.

Re: [Wicket-user] Chicken-and-egg w/ Data Provider

2007-05-30 Thread kroekle


The size() method was one of my biggest stumbling blocks when I started using
DataProvders, but for slightly different reasons (i.e. just having a size
method makes it less maintainable, perform worse, less scalable and gives
less accurate results).  But when I tried to work around the size method, I
found it was very deeply embedded in the inner workings of DataTable.  I
also think DataTable is too nice of a component to not use.  So I came up
with a solution that doesn't require the DataProvider to have a size()
method, but leaves it in DataTable.  I've submitted this to JIRA
(https://issues.apache.org/jira/browse/WICKET-579), but since it requires
changing core classes, I wouldn't suggest anybody implement it before it is
an accepted patch.  (but maybe some support from others will help it get
accepted).

 I'm trying to use a provider class for a DataView so I can do

 It works if size() makes a call to the database to get a count of
 records...but I'm trying to use a global field to prevent that data call.

 Any suggestions?

Re: [Wicket-user] Implementing a PopupPanel

2007-05-30 Thread John Krasnay

Ah, I see.

If your popup functionality is pure client-side Javascript, couldn't you
just turn it into a Behavior that you attach to a Label, Image, or
whatever, that sets the onclick attribute of whatever you attached it
to?

Thanks John. I was suspecting no one to reply to a long mail.
 
Unfortunately, in my case the getTitle() returns a component not the label
text. The component returned by the child can either be a label or an
image component. The derived class gets the label text in its
constructor which it uses to construct the label but the parent calls
getTitle() too soon.
 
As there are 2 components within the parent (title and contents) that the
child needs to fill, I could not use markup inheritance.
 
Thanks,

  To use it, new LabelLinkedPopupPanel(...) and override the getContent()

  1. Have a setTitle() and setContent() method that is called by the

  2. Have PopupPanel constructor take in components for title and content.
  The sub classes then just act as wrappers.
  3. Replace the subclasses with PopupPanelFactory with 2 methods

  I don't think a border suits this requirement but I'm not sure. Is there

[Wicket-user] How To Test with getApplication method

2007-05-30 Thread tma tma


Hi

I am not native English speaker.
sorry for poor English.

I use wicket 1.2.6 .
I have question to use WicketTester.

i want to make Global object ,create instance in WebApplication Class and
create method to access the instance.
In WebPage class ,access the instance like this

SingleClass class = ((FooApplication)getApplication()).getSingleClass();

'FooApplication' extends WebApplication and 'SingleClass' is Global object's
class.

To test the above WebPage class, make the class 'FooApplicationTester' that
extends WicketTester and
Copy  Paste the FooApplication's method .

when run the test code, ClassCastException happens.
I declared interface IFooApplication and implement at FooApplication and
FooApplicationTester.
I changed the WebPage class like this

SingleClass class = ((IFooApplication)getApplication()).getSingleClass();

This way, I can run without exception.
But I don't want to create interface.
Is there other way to solve ?

best regards

[Wicket-user] Best Practices for accessing/repainting sibling/cousin components?

2007-05-30 Thread dukejansen

I have some state which backs two panels, Panel A and Panel B, that may be
included as part of other panels. Ultimately they are both on the same page,
and their backing state is shared via the model class that backs both of
them. Panel A has an Ajax event handler which modifies the backing model
state, after which I want to force Panel A and Panel B to repaint.

I've dealt with this in a few different ways so far, and they all bother me:

1. Walk up the containership tree and back down again until I find the panel
with a known ID or which implements a specific marker interface, finding it
that way. (Or do a full DFS of the tree to be thorough.)

2. Assume how my Panel is included and how the other Panel are included, and
explicitly walk up and back down the containership tree. This is fragile
because if I decide to rework panel containership, the method could fail.

Is there some better way of doing this that I'm missing? A best practice for
reaching out to siblings and cousins?

Or something more fundamental to trigger refreshes of all componets backed
by that model? Seems like a common use case. A component updates some state
as part of ajax event, then wants to use ajax to repaint any other
components backed by that state.

Interested to hear how others have solved this problem.

Subject: Re: wicket scriptaculous drag and drop

Thanks for the feedback.  This question might be applicable to the

SortableListView for users that can drag/drop and a normal ListView
for users that can not sort.

something like:
if (canSort) {
  add(new SortableListView());
} else {
  add(new ListView());
}

I think this should be possible.

you need the acegi-framework from

http://www.acegisecurity.org/

and the spring.jar (acegi needs this for it's configuration - nothing else!).

if all libs/classes are in place, you can change the role-example to use
AcegiWebApplication and AcegiWebSession. make sure, that you have your Roles
configured in the acegi.xml! :-)

i think it's not 100% bulletproof but it's already usable. and you can
authenticate to what you like. :-)

if it's good enough and interesting for others, your welcome to add this to
the wiki.

best regards, --- jan.

Re: [Wicket-user] Chicken-and-egg w/ Data Provider

2007-05-30 Thread V. Jenks


I prefer not to do it that way because it requires a potentially large list
of records to be pulled up initially whereas now, I'm only pulling the
records on the current page, making it much faster.  I pass the x  y right
through to the data access layer.

 It works if size() makes a call to the database to get a count of

 Any suggestions?

[Wicket-user] DateTimeField surviving Ajax updates

2007-05-30 Thread Aaron Hiniker

I have a AjaxTabbedPanel that contains the Yahoo DateTimeField from 
extensions.  The calendar works fine on a page refresh, but when 
clicking to other tabs with Ajax loading each tab, the DateTimeFields 
quit working.  Has anyone else experienced this and found a workaround 
or fix?


Thanks

[Wicket-user] Adding more onclick script to ajax link?

2007-05-30 Thread Tremelune


I'm looking to add an additional script to the onclick of a (paging) ajax
link. I stumbled on this thread:

http://www.nabble.com/Appending-to-AJAX-Submit-Button-onclick-tf1695285.html#a4600751

I can't seem to find the additional code in 1.3. The thread is a year old,
perhaps the code was discarded. Is there a new and better way to add
additional onclick scripting somewhere else?

Re: [Wicket-user] Best Practices for accessing/repainting sibling/cousin components?

It shouldn't be hard to write the method you're talking about. To find all
the components using the same model as a given component, just walk the
component hierarchy using visitChildren() and add any component which
returns true for sameInnermostModel(component).

There is a more general case of this problem though where one area of a web
page may need to be updated because some completely unrelated area changed.
This I'm handling by hand right now, but I was asking a day or two ago if
there was a way to add a component to every ajax request (Eelco answered
that you can do this by implementing a request processor, I think). It
seems to be pretty common in an AJAX request to want a global feedback
component to update. Maybe we could have a poor-man's version of this where
if you override some boolean method, your component will get
auto-ajax-updated on every AJAX request. For many problems, this would be
convenient because it's easier to just update the thing every time than to
think about all the places it might need to be updated.

I have some state which backs two panels, Panel A and Panel B, that may be

both of them. Panel A has an Ajax event handler which modifies the backing
model state, after which I want to force Panel A and Panel B to repaint.

I've dealt with this in a few different ways so far, and they all bother
me:

1. Walk up the containership tree and back down again until I find the
panel with a known ID or which implements a specific marker interface,
finding it that way. (Or do a full DFS of the tree to be thorough.)

2. Assume how my Panel is included and how the other Panel are included,
and explicitly walk up and back down the containership tree. This is
fragile because if I decide to rework panel containership, the method
could fail.

Is there some better way of doing this that I'm missing? A best practice
for reaching out to siblings and cousins?

Or something more fundamental to trigger refreshes of all componets backed
by that model? Seems like a common use case. A component updates some
state as part of ajax event, then wants to use ajax to repaint any other
components backed by that state.

Interested to hear how others have solved this problem.

Re: [Wicket-user] Best Practices for accessing/repainting sibling/cousin components?

Maybe another way to auto-ajax-update a component would be to have it do
that whenever its model changes. There are a lot of caveats with model
change notifications, but that seems to be a pretty clean idea if the rules
for model changes were respected. Might make a good RFE for next Wicket
version.

[Wicket-user] Is it possible to remove something from a page?

2007-05-30 Thread Lowell Kirsh

I making a web page which contains some markup that I'd like to remove
(sometimes). I imagine it would look like:

...
span wicket:id=removeMeHello bW/borld/span
...

Is it possible to remove this markup?

+1. It can be tedious sometimes figuring out how to update
components that are on the other side of the tree from the onClick.

[Wicket-user] How to position the panel tab

I need some guidance. By default, normally we will see either a panel tab or
multiple tab appear on the far left of the screen. How do we position them (
the panel tabs ) in such a way that they will appear on the far right rather
than the left?
