Add input in javascript and process value in form?

[Per Newgro]

Hi,

i would like to add some input fields to an ul/li using JS.


  
function add_fields() {
  var d = document.getElementById("items");
  var i = d.childElementCount;
  d.innerHTML += "
";
}
  

  


  

  


  


Currently in Form.onSubmit values are empty.

Is this possible? Is there an example for this?

Thanks for your support

Extend session metadata with user-data-scope after login (spring question)

[Per Newgro]

Hi,

i would like to extend a session (metadata) with scope of user logged in. 
Something like "allowed countries", "allowed companies" and so on.
That scope is provided by a spring bean (UserScopeFinder). This bean is created 
in a Configuration as a @Bean.

What i tried so far is add an ISessionListener to WebApplication and inject the 
UserScopeFinder.


@com.giffing.wicket.spring.boot.context.extensions.ApplicationInitExtension
public class AuthorizationInitializer implements 
com.giffing.wicket.spring.boot.context.extensions.WicketApplicationInitConfiguration
 {

@Override
public void init(WebApplication webApplication) {
IAuthorizationStrategy strategy;
strategy = new ApplicationAuthorizationStrategy(new 
UserRolesAuthorizer());

webApplication.getSecuritySettings().setAuthorizationStrategy(strategy);
webApplication.getSessionListeners().add(new 
UserScopeInjector());
}
}

public class UserScopeInjector implements ISessionListener {

@SpringBean(name = "userScopeFinder")
private UserScopeFinder userScopeFinder;

public UserScopeInjector() {
super();
Injector.get().inject(this);
}

@Override
public void onCreated(Session session) {
System.out.println("Works");
}
}


But in that case i get:


...

Is there an example project for wicket-spring-boot with gradle and webpack?

To built my frontend assets (sass, js, svg minify etc) i like to use webpack.

But if i start my project the assets are not loaded. So i hope to find an

Is there a SOAP resource?

[Per Newgro]

Hello every1,

i would like to migrate some features of an web app to my wicket app.

The web app is a spring boot app that provides access to data using SOAP.
The web service extracts the SOAP request and calls my wicket app by using rest 
resource.

But now i need to replace the additional web app by my wicket app.

So far i do everything using rest resource. So i ask myself if there is a 
similiar component for SOAP.

Aw: Re: Wicket Spring boot - use spring devtools

[Per Newgro]

Hello Martin,

the problem is that i assign a model in request cycle metadata by using the key

public class IdentityInstance extends MetaDataKey> {

public static IdentityInstance KEY = new IdentityInstance();

private IdentityInstance() {
super();
}
}

Page:
getRequestCycle().setMetaData(IdentityInstance.KEY, identityModel);

Widget:
IModel identity = getRequestCycle().getMetaData(IdentityInstance.KEY);

But the model in Widget is always null. While debugging i found that object 
identity is used in Class#equals(Object o), what is ok for me.
But with different classloaders class is loaded multiple times.

I could provide a quickstart for this & create an issue, if you like. (?)

I would like to adapt my configuration so that devtools are still available.

(DCEVM i need to inspect :-).)

Thanks for your support.

Wicket Spring boot - use spring devtools

[Per Newgro]

Hello *,

I migrate my current wicket app to spring boot version 
(https://github.com/MarcGiffing/wicket-spring-boot).

So far it was straightforward. But now i experience a problem with inclusion of


org.springframework.boot

spring-boot-devtools


It seems that the "restart / reload feature" of devtools loads my classes 
multiple times, so that they are not equal anymore (x.class <> x.class).
I understand that this is happening. But i would like to know if there is 
another option for me beside - removing spring-boot-devtools.

Hi,

You can use Link#onClick() to count and then throw
RedirectToUrlException(urlFor(yourResourceReference)) that will lead to a
redirect.

Can I use wicket to emend my markup?

[Per Newgro]

Hello,

i try to render HTML markup with flying saucer to PDF.
In case i render the page by wicket and use that result markup in my flying 
saucer wicket resource, everything is ok.

Because i need to generate some SVG by browser using javascript (d3.js) i would 
like to send the markup from browser to my FS wicket resource.

My main problem is that sending the html by using 
document.documentElement.outerHTML destroys the markup. It cuts of the end-tag 
from my
link element. So the flying saucer complains on a missing link end-tag.

Example

My original html looks like this

http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;>



Apache Wicket Quickstart






Apache Wicket




after sending result of document.documentElement.outerHTML as form-data to 
wicket resource i receive

 
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;>

Apache Wicket Quickstart
http://localhost:8080/style.css; 
type="text/css" media="screen" title="Stylesheet">





...

The meta and link end-tags have been removed (i suspect the browser doing that).

Flying saucer complains then with
1:36:41.764 [qtp2116908859-19] WARN  RequestCycleExtra - Handling the following

Aw: Re: Re: Use Resource to transfer SVG to PNG

[Per Newgro]

My main problem is, that i can not send the svg text to the resource. Doing so 
by request parameters is not an option because the firewall will deny that long 
cryptic content.
Therefor i would like to send the svg content through a form.

So far i have the following:

In my page-markup (containing the svg) i have


  
  



var getSvg = function(element) {
var svgHtml = document.querySelector('#chart-container 
.highcharts-container').innerHTML;
element.querySelector('input[name="data"]').value = svgHtml;
}



In my page i have

add(
  new WebMarkupContainer("svgForm")
  .add(AttributeModifier.replace("action", 
PngResourceReference.url().toString(;


I've registered a resource by reference

app.mountResource("/svg2png", new PngResourceReference());

---

public class PngResourceReference extends ResourceReference {

private static final Key KEY = new 
Key(PngResourceReference.class.getName(), "svg-to-png", null, null, null);

public PngResourceReference() {
super(KEY);
}

@Override
public IResource getResource() {
return new PngResource();
}

public static CharSequence url() {

Aw: Re: Use Resource to transfer SVG to PNG

[Per Newgro]

Thanks for your response Martin.

I tried to make it work the whole day now. But i can not get it to work with 
IE11.
There is always a security error. This is a known problem for IE and canvas.

I ended up:

$("#chart-export").on("click", function() {
var svg = document.querySelector( "svg" );
var svgData = new XMLSerializer().serializeToString( svg );

var canvas = document.createElement( "canvas" );
document.body.appendChild(canvas);
var svgSize = svg.getBoundingClientRect();
canvas.width = svgSize.width;
canvas.height = svgSize.height;

var ctx = canvas.getContext( "2d" );
ctx.clearRect(0, 0, canvas.width, canvas.height);

var img = document.createElement("img");
img.setAttribute("crossOrigin", "anonymous");
img.onload = function() {
ctx.drawImage( img, 0, 0 );
var a = document.createElement("a");
a.download = "chart.png";
a.href = canvas.toDataURL( "image/png" ); 
document.body.appendChild(a);
a.click();
};
img.setAttribute("src", "data:image/svg+xml;base64," + 
btoa(unescape(encodeURIComponent(svgData))) );
});

So i need to go on the other way. But there my problems still occur.

Use Resource to transfer SVG to PNG

[Per Newgro]

Hello *,

I would like to generate a png from a svg. The transcoding is done by using 
Batik.
So far it works as expected.

But i'm not sure how to provide the resulting png (a byte[]) to my frontend.

The svg is generate in browser by using highcharts. I would like to provide a 
button
that downloads the transcoded png by sending a request to the "transcoding 
resource"
and using the svg-dom from browser.

Is there someone who did that already once? Can you please give me a hint how 
this could work?

Thanks for your support

ListViewEnclosurePage$MyListView.java
  public static class MyListView extends ListView {

public MyListView(
String id,

@Override
protected void populateItem(ListItem item) {
  Label label = new Label("bar", item.getModel());
  item.add(label);
  if (item.getIndex() == 1) {
item.setVisible(false);

Aw: Re: Re: ListItem and enclosure problem

[Per Newgro]

But wouldn't this only hide the complete listview when there is no item?
I want to remove markup only for an empty item.

So something like

  1
  2
  3


should become in case foo:1:bar is invisible


  1
  3

Aw: Re: ListItem and enclosure problem

[Per Newgro]

Sorry Ernesto for my bad english. But i can not see how i shall get this to 
work with a panel?
I use a listview because my item count is configurable. So i can not generate a 
"template panel"
and put all items in that. But i admit that i didn't understand your question 
completely.

Aw: Re: ListItem and enclosure problem

[Per Newgro]

Thanks for responding.

Maybe i should have stated my goal clearly. I would like to remove the space 
occupied by empty list items.
Basically i do it with wicket:enclosures. While not displaying the "empty 
element" markup the space is not occupied.

Do you mean that i need to change it that way?

ListItem and enclosure problem

Hello,

i would like to enclose markup of a list item in wicket:enclosure. The 
enclosure is activated based on a child component on list item.
So for i could not find any marker that this is not working. So i need to do 
something wrong. Any work around would be welcome.

Thanks for your support

How can i authorize a 'bot' to access my REST resource?

[Per Newgro]

Hi,

i've extended an org.wicketstuff.rest.resource.AbstractRestResource and mounted 
it in my WebApplication.
Everything works so far.

But i've annotated my Method with a role that shall be extracted from the 
session. I'm not quite sure how to
'login' my import command (CLI) as a user

Find a component corresponding to entity

[Per Newgro]

Hello *,

I'm looking for an elegant solution to determine a component for an entity.

Example:
There is a person and two sub-types of it - Manager and Sportsman.
The Manager can be listed in a listview by using a ManagerViewItem
and the Sportsman by using a SportsmanViewItem.

Currently I'm using a factory producing the appropriate viewitems. But this 
factory is injected by using spring.
I would like to reduce the coupling to spring within my component classes (e.g. 
Page).

So i'm looking for a "wicket way" to determine which component is required to 
list all persons.

Thanks for your ideas.

Hi all,

in my Wicket app I'm using properties.xml files for my i18n texts,
like described in the wiki[1]. The problem I have is that the files
are differently up to date, depending on the language and how
important it was for somebody to translate one exact key for one
special language etc. the only thing I really know is that English is
up to date...

So, does anyone knows a tool which expects translation files in a dir
structure and compares all found to their English base file? In the
end it should simply print which file in which dir is missing which
key compared to the English base.

Such a problem sounds common to me, but I couldn't find any good
software dealing with it yet.

Re: Filtering capabilities in TH (Array Header) or for dataview.

Maybe you can use
org.apache.wicket.extensions.markup.html.repeater.data.table.filter.FilterToolbar

It's in wicket-extension library.

Reanimate project from wicketstuff sandbox

[Per Newgro]

Hello,

maybe someone has some experiences with the topic and can support me.

I would like to update wicketstuff/sandbox/wicket-contrib-jamon.
I already forked the sandbox and transfered code from 1.3 to 1.4 to 1.5 
to 6 and now to 7.
Almost all problems are solved. There are some strange tests which 
checks that something is NOT running for 1.3
Maybe the founder of that project can give me some hints on this. But 
anyway.


I would like to clearify the next steps to publish my work to the community.

So far i've read the wicketstuff-wiki - contribute a new project - while 
it is not new :-).


I firstly need to adapt the project structure and put it unter 
wicketstuff/core. Do i need to fork wicketstuff-core

or can i request write-access to orginal repo?

My current master contains the wicket-7 version do i need to support 
earlier versions to? It would be no big problem.
Do i need to create a branch for every version then or is it enough to 
manage branch 1.3.x, 1.4.x and so on?

Re: Best Practice - Create component by entity type?

[Per Newgro]

This sounds good. I already have a registry where i can register services in a 
decoupled way. With spring and @PostConstruct no Problem :-). I would ASK then 
every factory if it is responsible for my entity type. But i still see a 
problem here. How to prioritize factory if i have more than one factory for a 
Person type. For instance if a boss is a manager. Then i can't use instanceof 
in the manager factory because boss entity would match twice.

Am 03.07.2015 3:14 nachm. schrieb Rob Audenaerde rob.audenae...@gmail.com:

 Hi Per, 

 You can do something like this: 

 Create a set of compontents that will be your panels to display specific 
 Persons. 

 Let's call them PersonPanels. 

 You can introduce a PersonPanelFactory, which might give you the 
 appropriate PersonPanel based on the class of the Person ( 
 person.getClass() ) . This is however not yet nicely extensible, but you 
 decoupled the logic for creating panels from your list-code. 

 Next step: you need to register the classes somehow so you can provide 
 panels for in the factory, so the factory can for example use a map to 
 provide the proper PersonPanel. You can use reflection to call the 
 constructors, which will need to have the same arguments for their 
 constructors. This is the biggest disadvantage I think in this approach. 

 Somewhat like this: 

 class PersonPanelFactory 
 { 
    public PersonPanel getPanelFor( ClassT extends personClass) ... 
   public registerPanelFor ( ClassT extends Person personClass, ClassT 
 extends PersonPanel personPanelClass ... 
 }

 Hi,
 
 ListView have special requirements when being used in a Form. See
 ListView#setReuseItems(boolean) javadoc.
 
 I guess it is better to use another repeater when you want to keep the page
 stateless.

How can i avoid that urls in src attributes are handled by wicket?

Hi *,

we have a page which contains markup like this

...
script type=text/x-handlebars id=template

After rendering the page the markup looks like this
script type=text/x-handlebars id=template
img src=../{{ url }} alt={{ name }} /
/script

Please note the ../ before the {{ url }}

Until now i thought that wicket handles only markup within html tags containing 
a wicket:id.
But it seems that Wicket gone wild here :-).

If i add this input markup

So i'm not able to get a valid form submit with a value of 12.5 because

Because the w3c-spec says

and

Positive floating-point number #
A non-negative floating-point number, with the following restriction:
must be greater than zero

it should be valid to use 0 or 0 as special constant in NumberTextField.

NumberTextField

and


@Override

{
...

if (step != null)
{

}
else

This should do the trick without any change in current behavior.

Is Behavior.beforeRender useful for component configuration?

[Per Newgro]

Hi,

we have an admin menu in our menu bar. All items in admin menu are 
configured by @AuthorizeAction.
I would like to hide the admin item in main menu if no menu item is 
visible in the admin menu (e.g. user is not an admin).


To avoid repeating myself in every onBeforeRender method of the included 
components i've tried to use a behavior.
It tries to hide parent by checking if all items are invisible and 
configure the parent's visibility.


But this is not working (configure(component) and beforeRender(component)).
Configure is not usable because the render permission (setRenderAllowed) 
is determined after the Behavior.onConfigure was called.

So the action takes place before the child is authorized.

Then i thaught let's do it in beforeRender. But there we got a message

org.apache.wicket.WicketRuntimeException: Cannot modify component 
hierarchy after render phase has started (page version cant change then 
anymore)

at org.apache.wicket.Component.checkHierarchyChange(Component.java:3595)
at org.apache.wicket.Component.addStateChange(Component.java:3524)
at org.apache.wicket.Component.setVisible(Component.java:3213)

This is comprehensible for me so far. No change after rendering started. 
But how shall i hide the parent without repeating myself in
every Component.onBeforeRender method? This is working. But i have to 
duplicate my code for ListItem, ListView and AdminPanel.


We use wicket-6.11

Thanks for helping me out of the wood.

Re: Is Behavior.beforeRender useful for component configuration?

[Per Newgro]

Hey Paul,

thanks for your reply.

Sadly i can not use Behavior.configure(Component). The code will be 
executed (see Component.configure)
before the render action is granted to the component by applying the 
isActionAuthorized(Render).

See Component.java line 1030 to 1039 for details.

Do i have another option?

Thanks

Do you want the configuration code to run each time before the component

Then go ahead and place your code there, otherwise if you only want the
configuration code to run only once see the onConfigure() method:

/**
   * Called immediately after the onConfigure method in a component. Since
this is before the
   * rendering cycle has begun, the behavior can modify the configuration of
the component (i.e.

[auth-roles] Design of x-RoleAuthorizationStartegy

[Per Newgro]

Hi,

we had a simple usecase today leading us to confusion on 
AnnotationsRoleAuthorizationStrategy (ARAS).

We tried to protect a button by using two different permissions. So we had to 
use AuthorizeActions.
We did it this way
code
  @AuthorizeActions(actions = {
@AuthorizeAction(action = Action.RENDER, roles = { entity.create }),
@AuthorizeAction(action = Action.RENDER, roles = { document.fillout })
  })
  private static class NewDocumentForNewEntityLink extends 
BookmarkablePageLinkVoid {
public NewDocumentForNewEntityLink(String id, Class? extends WebPage 
pageClass) {
  super(id, pageClass);
}
  }
/code

Ok we don't use the roles as their name would suggest it. We use it more as 
permissions.
But that is not relevant here (IMHO).

In one of our test cases we've found out that only one permission is required 
to get
that link displayed. But we would like to include all permissions. And so the 
story begins.

The first maybe intuitive way to customize the annotation handling was to 
implement our own
IRoleCheckingStrategy. But the first issue we had was the name of the interface 
method we
had to implement (hasAny(Roles)) which suggests an or condition.

= Isn't this to thight for an interface? Shouldn't the name be accepts(Roles)?

With further checks we saw no chance to get an and condition check done by 
the current
ARAS implementation. The only possibility was to overwrite 
code
protected boolean isActionAuthorized(final Class? componentClass, final 
Action action)
/code
and do it by our own. Another problem could be the handling of the deny 
permissions.
If we would like to use an or condition check here this wouldn't be possible 
because
accept and deny checks use the same method (hasAny(Roles)).

= Shouldn't the role check a task of the RoleCheckingStartegy? Shouldn't it be 
a more
configurable implementation? 

I hope my problem got clear. I don't want to snub anybody. The intention of 
this is
only to have a discussion here before we create a ticket with a patch.

What do you think?

Strange behavior on first page request with jetty from Start.class

Hi,

has someone seen the following behavior and can give me a hint?

I do some changes on my project.
Then i use the Start class (provided by quickstart) to start the

And then page loading is really slow  2min
or
Page is rendered but there is no javascript (at least the scripts are 
not executed).


If i reload the page (by pressing F5 in FF) then everything is rendered 
fine and works as expected.

But not on the first request.

Is this only on my side?

 Hi,
 
 Are you saying that the event of clicking the bookmarkable link (the a)
 bubbles to the div ?
 I think it should not happen. Clicking the link changes the document
 location... But I may be wrong.
 
 A simple solution is to add onclick=Wicket.Event.stop(event); return
 true; to the a element.
 This calls event.stopPropagation().

Re: Model for dropdowns in a listview

[Per Newgro]

Hello Rodrigo,

sure i know that the null has to be replaced by a model. But my 
question was

targeted to the object behind the dropdown selected option model.

Let me create a more simple example:

code
MyComponent.java
- in constructor -
IModelReplyOptionsCollectingModel formModel = 
Model.ReplyOptionsCollectingModel of(new ReplyOptionsCollectingModel())

Form? form ...;
form.add(new DropDownChoice(replysForQuestion1, new 
PropertyModelReplyOption(formModel, answerForQuestion1), 
replyOptionsForQuestion1()));
form.add(new DropDownChoice(replysForQuestion2, new 
PropertyModelReplyOption(formModel, answerForQuestion2), 
replyOptionsForQuestion2()));


ReplyOptionsCollectingModel.java
public class ReplyOptionsCollectingModel implements Serializable {
  private ReplyOption answerForQuestion1;
  private ReplyOption answerForQuestion2;

  // ... getter and setter
}
/code

But because i don't know the count of questions i have to use a 
repeating view.


code
MyComponent.java
- in constructor -
IModelReplyOptionsCollectingModel formModel = 
Model.ReplyOptionsCollectingModel of(new ReplyOptionsCollectingModel())

Form? form ...;
ListViewQuestion questions = new ListView(...) {
   protected void populateItem(ListItemQuestion item) {
  item.add(new DropDownChoice(replysForQuestion, new 
PropertyModelReplyOption(formModel, I_dont_know_what_to_add_here), 
replyOptionsFor(item.getModelObject(;

   }
}
form.add(answers);

ReplyOptionsCollectingModel.java
public class ReplyOptionsCollectingModel implements Serializable {
  private MapQuestion, ReplyOption answerForQuestions;
}
/code

Or do you mean that CompoundPropertyModel has more features
handling the indexed-property stuff?

Thanks for your support

Model for dropdowns in a listview

[Per Newgro]

Hi,

i have to implement a questionnaire but i'm not sure how to capture the 
selected values in a model.


My questionnaire has some questions. The questions have some reply options.
The selected reply options will be assigned to an answer. The answers 
are the data i try to capture.


So i put the questions in a listview and a dropdown for the reply 
options on it's item.
But i have no clue how to implement the business model containing the 
answers.

Every answer is related to one selected reply option.

Can some1 please give me some pointers. Thanks for your support.
Per

Here some code

code
public class QuestionListView extends ListViewQuestionBO {

public QuestionListView(String id, IModel? extends List? 
extends QuestionBO model) {

super(id, model);
}

@Override
protected void populateItem(ListItemQuestionBO item) {
item.add(new Label(questionText, new 
PropertyModelString(item.getModel(), QuestionBO.TEXT)));
// TODO the null has to be replaced by a smart model 
assigning the selected reply option to an answer in the business model
item.add(new DropDownChoiceReplyOptionBO(replyOptions, 
null, new LoadableDetachableReplyOptionsModel(item.getModel()), new 
ReplyOptionBORenderer()));

}
}

public class LoadableDetachableReplyOptionsModel extends 
LoadableDetachableModelList? extends ReplyOptionBO {


private final IModelQuestionBO question;

public LoadableDetachableReplyOptionsModel(IModelQuestionBO 
question) {

this.question = question;
}

@Override
protected List? extends QuestionBO load() {
return service.loadReplyOptionsFor(question.getObject());

Re: Wicket integration with Spring

[Per Newgro]

With the 2nd approach you couple the application (in the role as service 
mother) to all your calling components.
Coupling is a bad idea. It's hard to test in separation and almost 
always you end in a hell of small single methods.
But if you inject your beans into the target component you can define 
your required dependeny there were you use them.
Another cool approach in wicket is the event system in 1.5+. So you 
throw events in child components and provide the

services in high ranking components (page, app ...)

Just my 2 ct.

ways on how to inject Spring   Beans into Wicket pages.

public class FormPage extends WebPage

2. The @SpringBean is of course valid and considered a best practice by
many. But there is also *another approach*, where your Wicket Application
has the services you need.

public class YourWicketApp extends WebApplication{
   public static YourWicketApp get(){
 return (YourWicketApp) Application.get();
   }
   private ServiceA serviceA;
   // getter and setter for serviceA here
}

Now in your component, call

YourWicketApp.get().getServiceA();



I want to know which is the best way to integrate spring with wicket.


/However as far as I remember Wicket pages and components aren't managed by
Spring container so you cannot use @Transactional annotation on them (which
is a bad idea anyway - transactions belong to deeper levels)./ *Is this
statement valid?*

Hi,

we had a similar requirement, so we did the following:

instead of throwing a AbortWithHttpErrorCodeException, we throw a
semantic exception. In your case, throw MissingSubsiteException( your
message ).

How to make Wicket aware of such an exception and implement a proper
reaction/response?

In your application's #init()-Method, add a RequestCycleListener (e.g.
extends org.apache.wicket.request.cycle.AbstractRequestCycleListener)
which implements #onException() to dispatch to a particular error page
depending on the exception passed in. AFAIK, this is regular Wicket
stuff and nothing terribly internal (right?).


We have a bunch of error pages which are regular WebPages with
#isErrorPage() returning true. Those are triggered via the mentioned
RequestCycleListener by means of a
org.apache.wicket.request.handler.PageProvider, which can be used to
initialize the page just as you may need it. For example, by passing the
exception's message, or the exception itself to also display the stack
trace.

Such an error page can also set a status code by using #getResponse() in
#onBeforeRender(), i.e. set a HttpResponseCode.SC_BAD_REQUEST for
missing parameters.

I hope this helps,
bye

Re: Why can't CssUrlReferenceHeaderItem have dependencies?

[Per Newgro]

Hi Martin,

i use the UrlResRef like the normal ResRef. A specialiced css is depending
on a base css.
This base css should be guaranteed on special css usage.

public class PortalCssDependingResourceReference extends
UrlResourceReference {

private final String portalId;

public PortalCssDependingResourceReference(String resourceUrl, String
portalId) {
super(Url.parse(resourceUrl));
this.portalId = portalId;
}

protected final String getPortalId() {
return portalId;
}

@Override
public Iterable? extends HeaderItem getDependencies() {
ArrayListHeaderItem dependencies = new ArrayListHeaderItem();
for (HeaderItem headerItem : super.getDependencies()) {
dependencies.add(headerItem);
}
dependencies.add(CssHeaderItem.forReference(new
PortalCssResourceReference(this.portalId)));
return dependencies;
}

@Override
public boolean isContextRelative() {
return true;
}
}

It is included as expected with this (sample) code in my page. And this is
the cause why i'm wondering this is not implemented.

@Override
public void renderHead(IHeaderResponse response) {
final PortalCssDependingResourceReference reference = new
PortalCssDependingResourceReference(resources/special.css, getPortalId());
response.render(new
CssUrlReferenceHeaderItem(reference.getUrl().toString(), null, null) {

@Override
public Iterable? extends HeaderItem getDependencies()
{
return reference.getDependencies();
}
});
super.renderHead(response);
}

Re: Why can't CssUrlReferenceHeaderItem have dependencies?

[Per Newgro]

code
response.render(CssHeaderItem.forReference(reference));
/code

created a css link like this:
link rel=stylesheet type=text/css 
href=../../resources/portal/css/portal.css /

What i've tried to get is this:
link rel=stylesheet type=text/css href=/resources/trauer/css/portal.css 
/

We have all our css in an external folder (apache DOC_ROOT static). So this url 
is required.

But now i'm in doubt that i've misused the ResRef and HeaderItem concepts.
It seems to be more natural to extend the CssUrlHeaderItem and provide the 
dependencies there instead of connecting this to the ResourceReference and 
delegate the call. Maybe that is cause of how this is implemented.

 Hi,
 
 Why do you use  reference.getUrl() to create CssUrlReferenceHeaderItem ?
 Why not just : response.render(CssHeaderItem.forReference(reference));
 
 CssUrlReferenceHeaderItem by itself works with plain Url and there is no
 way how Wicket can know that it may depend on some other dependencies.

Why can't CssUrlReferenceHeaderItem have dependencies?

[Per Newgro]

Hi,

i was wondering why CssUrlReferenceHeaderItem (wicket 6.2.0) is implemented by 
HeaderItem#getDependencies() which returns an empty list.
The CssReferenceHeaderItem has a getDependencies implementation
which uses the dependencies provided by the resource reference.

If i extend CssUrlReferenceHeaderItem (for testing) and provide the 
dependencies of the resource reference (analogoues to CssReferenceHeaderItem) 
everything works fine.

But maybe i miss here something. So my question is: Is it required that 
CssUrlReferenceHeaderItem is not handling dependencies of the resource 
reference?

Thanks for explanation.

Is there a MountedMapper respecting better matching path names?

Hi,

before i do this myself i would like to ask the community if someone has done 
this already.

I want to mount pages at these urls:
mountPage(/pages/${color}/advertise, AdvertisePage.class);
mountPage(/pages/${color}/${niceColor}, ColoredPage.class);

But because they both have 3 matching url path segments the first after sorting 
all available mount mapper wins. But in this case the almost exact url 
/pages/red/advertise is referencing the ColoredPage but should the 
AdvertisePage. Only ordering the mounts is influencing the result. But this is 
not a good option.

So i would like to know if there is already a library providing my required

Re: WicketTester Spring

[Per Newgro]

And the app should know the context in which way? No no you have to set 
the app to wicket tester instance.

code
tester = new WicketTester(new MyApp());
/code

Hi

I have a content area in which I am displaying say PanelA. In PanelA I have
a link to navigate to PanelB. When I click that I replace the content area
with PanelB. When I construct PanelB i pass the instance PanelA via
PanelA.this so that PanelB can show a link to go back to PanelA. When the go
back link in panelB is clicked I do a replace content area with the object
(instance of panelA) I recieved in the construtor.

This works perfectly fine and the to n fro navigation is quick. It does not
reload the whole stuff again. Done. But I need to reload some of the data
changed in backend when coming from PanelB back to PanelA. Right now the
PanelA shows the old data it does not re-load.  I tried using the
LoadableDetachableModel but that does not get triggered.

Any clue please..

Re: help with drag and drop (wicket-dnd)

[Per Newgro]

Hi Dan,

only a shot in the dark - but is your markup valid? validate with w3c.

PS: Is it required to add the ending slash?

Cheers
Per

Thanks for answer.
Yes, in the first td is span but in this forum it was formatted and span
was not visible.
The first td should be:td  span wicket:id=aaa class=aaawww/td
--

But I make little modification and html is:
table
tr
td  span wicket:id=aaa class=aa/td
td  span wicket:id=bbb class=bb/td
td  span wicket:id=ccc class=cc/td
/tr
/table

And in java class was added:
Label bbb = new Label(bbb, bbb);
Label ccc = new Label(ccc, ccc);
bbb.setOutputMarkupId(true);
ccc.setOutputMarkupId(true);
container.add(bbb);
container.add(ccc);



But in the methods is transfer.getData() allways NULL. What should be in
transfer? The target element? Is there any way how to know what element was
targeted (drop)?

Re: get key from resource model

[Per Newgro]

If you mean get the key from ResourceModel, or ... then the answer is 
no not directly.
An ugly solution could be - extend ResourceModel and memorize the key in 
a second attribute.

But that's realy ugly.

class MyResourceModel extends ResourceModel {
  private String key;

  public MyResourceModel(String key) {
super(key);
this.key = key;
  }

  public String getTheKeyOnUglyWay() {
return this.key;
  }
}

But i would do this only if no other solution is possible.

Re: StatelessForm: Cannot login

[Per Newgro]

If i understood your usecase correctly you're app is still stateless if 
you logged in.
Afaik no session is created for stateless pages. So after you've logged 
in the session
is away for your next page. And then the user is away to. You could 
debug it by print the

hashcode of getSession() in the page.

Hello,

I have a strange problem with StatelessForms in combination with login in:
On my MainPage are two stateless forms. One for registration and one for the
login (registration isn't implemented yet). When I try to log in, Wicket
creates a new User() and saves it in the Session (I made this like it's
explained in Wicket in Action). A System.out.print(user created) in the
constructor of User confirms that. Everything seems to be ok. But when the
main page reloads, I am still logged out.
And: When I change from StatelessForm to Form, everything works perfectly.
Something else might be important: When I request a page that requries
authorization and I'm not logged in, i'm being redirected to /login. There
is the same LoginPanel (with StatelessForm) as on the main page - and the
login works! But when I directly open /login it's the same as on the main
page and I can't login.
I also noticed that the login works (with StatelessForm) when I open a page
that requires authorization, then press the back button (back to main page)
and there try to log in.

The question is now, what am I doing worng? I can't find the problem in my

Re: What to add to pom.xml to use hibernate?

[Per Newgro]

Hmm. Firstly you ask the wrong list. Hibernate is off topic.
At second - did you do a search? With maven hibernate i
found this link quickly:
http://stackoverflow.com/questions/3345816/hibernate-projects-and-building-with-maven
See the answer with the green check at the side. I think that will 
anser you question.

You have to exhange the version numbers by 4.0.1...

I'm interested in using hibernate in my wicket application, but I

Is there something other than hibernate that the wicket community uses for ORM?

If not, what can I add to the pom.xml file to include hibernate. I
tried adding this:

dependency

artifactIdhibernate/artifactId
version4.0.1-Final/version
/dependency

but it doesn't work. I an error that it Could not resolve dependencies

I also attempted to add this alongside the other repository that is there.

I get the error about Could not resolve dependencies for project...
but now many other jar files are not found.

I started with the quickstart, if that helps.

Hello, Everyone,

I am trying to build a web app with Wicket, EJB3, and MySQL. My IDE is
Netbeans 6.9.1 and the server is Glassfish 3.1.

I have created two entity beans 'Centre' and 'User', and one Centre has many
User(s). I also created two Facades for them.

The Wicket page used to list the Users is as below:


class ListUsers extends WebPage {

 @EJB(name = UserFacade)
 private UserFacade userFacade;

 public ListUsers(Centre c) {
 ListUser  users;
 if (c == null) {
 users = userFacade.findAll();
 } else {
 users = new ArrayListUser(c.getUserCollection());
 }
 final ListViewUser  list = new ListViewUser(eachUser, users) {

 @Override
 protected void populateItem(ListItem item) {
 final User user = (User) item.getModelObject();
 item.add(new Label(username, user.getUsername()));
 item.add(new Label(fullname, user.getFullname()));
 item.add(new Label(email, user.getEmail()));
 item.add(new Label(centreid, user.getCentre().getName()));
 }
 };
 add(list);
 }
}
-

The page to add a User is following:


 public AddUser(Centre c) {
 user = new User();
 user.setCentre(c);
 FormAddUser  form = new FormAddUser(AddUser) {

 @Override
 protected void onSubmit() {
 userFacade.create(user);
 }
 };

 form.add(new TextFieldString(username,
 new PropertyModel(user, username)).setRequired(true));

 PasswordTextField tf_password = new PasswordTextField(password,
 new PropertyModel(user, hashedPassword));
 form.add(tf_password);

 form.add(new TextFieldString(fullname,
 new PropertyModel(user, fullname)).setRequired(true));

 TextField tf_email = new TextFieldString(email,
 new PropertyModel(user, email));
 form.add(tf_email);

 LoadableDetachableModel centres = new LoadableDetachableModel() {

 @Override
 protected Object load() {
 return centreFacade.findAll();
 }
 };
 DropDownChoiceCentre  ddc = new DropDownChoiceCentre(centreid,
 new PropertyModelCentre(user, centre), centres,
 new ChoiceRendererCentre(name, name));

 form.add(ddc.setRequired(true));

 add(form);
 }
}



The problem is I can't see the newly added User in the list with
getUserCollection() method of Centre, but I do see the new User if I use
userFacade.findAll() method. Could you please help me and point me to the
right direction? I am quite new to Wicket and EJB3. Any comments are welcom.
Thanks a lot.

Re: how to get https port number in Wicket 1.5

[Per Newgro]

Thanks for testing this out. I wasn't aware of that.

I didn't understand the usecase exactly. You want to set the page / 
request secure

if you've added the login form? Or do you want to secure the form only.
For the later a possible answer is this
http://stackoverflow.com/questions/96164/partial-site-ssl-using-asp-net-login-control
It's a .net answer but the issue seems to be the same.

Hi Per,

The documentation for @RequireHttps implies that it only works for pages,
not components, and my (limited) testing shows that to be the case. Is there
a way to use it with components on otherwise insecure pages?

My use case is to secure a form on non-https pages, specifically to secure
that very nice username/password field at the top of Twitter Bootstrap
pages.

What is the cause for log entry ModificationWatcher - Cannot track modifications to resource

[Per Newgro]

Hi,

If i test my app by using Start.java i get the log entry
INFO  - ModificationWatcher- Cannot track modifications to 
resource 
file:/D:/Dokumente%20und%20Einstellungen/per.n/Eigene%20Dateien/workspaces/work/whataschranz/target/classes/ch/newgro/shop/whataschranz/welcome/HomePage.html

If i change the HP Markup it's not reloaded.

Google only pops up an answer by igor
not sure you can do anything about the message...just disable the 
logger for that class/package...


But disabling the log message is not solving the problem, that my markup 
modifications are not re-loaded :-).
As far as i investigated this issue is a problem with the encoded path 
string (%20) used to load the resource by
org.apache.wicket.util.resource.locator.ResourceStreamLocator#locateByResourceFinder. 

I'm not an expert but i think i've read a message that something changed 
here (URI class or servlet-api)

but maybe someone else already solved this.

My question is - Is this a bug or can i configure something to make 
resource modification watcher working?

Hello list

We built a rendering engine in Wicket 1.4 which takes a UI description 
from an XML file and builds an HTML representation from that. 
Everything worked fine in Wicket 1.4.x.


Now I tried to switch to Wicket 1.5.3. Without changing anything from 
the rendering part, I now get this error:


 org.apache.wicket.WicketRuntimeException: The component(s) below
 failed to render. A common problem is that you have added a component
 in code but forgot to reference it in the markup (thus the component
 will never be rendered).

Below that message I get a list with all components.

We mostly use ListViews to build the UI:

ListViewObjectBase listView = new 
ListViewObjectBase(eachGuiElem, formRoot.getChildren())

{
@Override
protected void populateItem(ListItemObjectBase item)
{
ObjectBase ob = item.getModelObject();

item.add(new Panel(...));
}
};

So here is my question. What did change with Wicket 1.5? How can I 
make our renderer work again? Where should I look at to find out whats 
wrong?


Thanks,
Adrian

Re: display artifact version in webpage

But this causes a build / version control system issue.

Guess you use version control like svn or cvs. Once you checked in the 
html markup

and call a build the markup changed and you have to check in markup again.
So that becomes a chicken - egg - problem.
