[Wicket-user] setResponsePage() to a mounted link
I have links that allow to change the locale, like so:
add(new Link(toEnglishLink)
{
public void onClick()
{
getSession().setLocale( Locale.ENGLISH );
}
});
In principle, this works fine. The only problem is that it messes up my
bookmarkable links (mounted). For instance, instead of pointing to
/some/mounted/path
as intended, it ends up pointing to:
/app?someParameterStuff
What is the best way to provide functionality to a link component
without messing up mounted links? Would I absolutely be required all the
time to pass in the locale as a paramter?

[Wicket-user] Newbie question: applying dynamic form component with ListView
Hi,Which type should I define in POJO Model to hold the value of the array of TextField/DropDownChoice when populated by ListView? Should I define it as String[] or ArrayList or something else? I have attached the following example to explain my situation: public class DetailForm extends Form { private java.util.List ageList = Arrays.asList(new String[]{ "10", "20", "30" }); public DetailForm(String string){ super(string); DetailModel dm = new DetailModel(); setModel(new CompoundPropertyModel(dm)); ListView listView = new ListView("detailList", new
PropertyModel(this, "detailData")){ public void populateItem(final ListItem listItem){ final String detail = (String) listItem.getModelObject(); listItem.add(new Label("code",detail)); listItem.add(new DropDownChoice("age",ageList)); listItem.add(new TextField("name"));
} }; add(listView); } public List getDetailData(){ java.util.List hm = new ArrayList(); // Should get the data from DB, for simplicity I use hardcode value hm.add(""); hm.add(""); hm.add(""); return hm; } }&
nbsp; //
Model class public class DetailModel implements Serializable { private String[] age = new ArrayList(); // Not sure about the type private String[] name; public String[] getAge(){ return age; } public void setAge(String[] age){ this.age = age; } public String[] getName(){ return name; } public void
setName(String[] name){ this.name = name; } }The idea behind String[] was my 'past time' with Struts :) Any suggestion?Cheers,Michael

It also adds more magic to the wicket core. I'm not sure if I like more magic.

no again. then you set an instance. And getPage() is the same as doing nothing because that is thepage where we return to by default.So if you set the response page to a page instances we can't redirect to a mount because a mount is
a bookmarkable pageWhen targeting a instance the url must be something like wicket:xxx:0johanOn 3/15/06, David Leangen

I've done or rarther are trying to do this by using the wicket radiochoice and a wicket ListMultipleChoice. And are overiding the onSelectionChanged and the wantOnSelectionChangedNotifications, so that onSelectionChanged does what I want and wantOnSelectionChangedNotifications returns true. However now I get this error: [PoolThread-9] ERROR wicket.RequestCycle - Unexpected runtime exception [page = null] wicket.WicketRuntimeException: Attempt to access unknown interface IOnChangeListener And I am a little confussed on why I am getting this error since the RadioChoice already implements the interface so it should be known? Only other option is that the error conseals another error which is caused by something else? I have a similar control which has this functionality, instead of using a radiochoice onselectionchange it uses a button to make something similar. I'll be happy to send the code and log, or just give a more detailed explaination. -regards Nino

please please guys what can be wrongisnt it as basic as

add(new AjaxLink(link) { public void onClick(AjaxRequestTarget ajaxRequestTarget) { Label b = new Label(a,B); ajaxRequestTarget.addComponent
(b); }});
is there some configuration i am not putting in place?
Re: [Wicket-user] wicket:1.1.1 error unknown interface IOnChangeListener?

RE: [Wicket-user] DataView (extentions)
The DataTable in Wicket Extensions 1.1 handles paging and sorting, but you must build a custom IDataProvider that accumulates the sorting instructions from the DataTable and provides sorted subsets of the data when requested by the DataTable (which handles the actual paging display). DataTable and supporting classes have been greatly refactored in Wicket Extensions 1.2 to give the user much more flexibility in the set of features desired. The API changes will break Wicket 1.1 programs, so if you need to subclass anything to modify its behavior, I would suggest going to Wicket 1.2 now. Otherwise, you can upgrade fairly easily at any time by replacing Wicket 1.1 DataTable with Wicket 1.2 DefaultDataTable. Wicket 1.2 DataTable is more flexible but less complete; DefaultDataTable subclasses it to provide defaults which make it behave like the Wicket 1.1 DataTable. I have come up with my own subclass of DataTable and implementation of IDataProvider to display any arbitrary database java.sql.ResultSet. The basic idea is that my IDataProvider implementation contains a List of rows, each row consisting of a List of Object. Also in the implementation is an array of descriptors, one per column, each of which contains the column name and an indicator as to whether I want to be able to sort on that column. (The column name comes from the ResultSetMetadata; a method is provided to set the sortability flag.) My implementation of the abstract method to deliver a sequence of rows will delegate to the List.sublist() command from the Java Collections API, and each time the DataTable delivers a sort criteria I apply the Collections.sort() method to my list of rows, passing it a Comparator that delegates to the Comparator of the Object at the relevant column index. My implementation of IDataProvider can also look at my array of column descriptors and generate a list of IColumn objects (needed to construct the DataTable). Its actually a bit more complicated than that (and a work in progress), because I have complicated the above mechanisms to deal with the possibility of a summary row at the end, and when rows are requested, the query string will be recalculated based on form data -- and if it has changed since the last request then the data will be refreshed from the database and the current page set back to 1. The code is actually quite compact; when Im finished Ill post it to the list if there is any interest. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Igor Vaynberg Sent: Tuesday, March 14, 2006 5:21 PM To: wicket-user@lists.sourceforge.net Subject: Re: [Wicket-user] DataView (extentions) there is also a DataTable component which wraps DataView+paging+sorting. -Igor On 3/14/06, Vincent Jenks [EMAIL PROTECTED] wrote: I'm using 1.1.1 Are there any plans to whittle down the amount of code it takes to implement paging sorting?

The API changes will break Wicket 1.1 programs, so if you need to subclass anything to modify its behavior, I would suggest going to Wicket 1.2 now. Otherwise, you can upgrade fairly easily at any time by replacing Wicket 1.1 DataTable with Wicket 1.2 DefaultDataTable. Wicket 1.2 DataTable is more flexible but less complete; DefaultDataTable subclasses it to provide defaults which make it behave like the Wicket 1.1 DataTable. I have come up with my own subclass of DataTable and implementation of IDataProvider to display any arbitrary database java.sql.ResultSet. The basic idea is that my IDataProvider implementation contains a List of rows, each row consisting of a List of Object. Also in the implementation is an array of descriptors, one per column, each of which contains the column name and an indicator as to whether I want to be able to sort on that column. (The column name comes from the ResultSetMetadata; a method is provided to set the sortability flag.) My implementation of the abstract method to deliver a sequence of rows will delegate to the List.sublist() command from the Java Collections API, and each time the DataTable delivers a sort criteria I apply the Collections.sort() method to my list of rows, passing it a Comparator that delegates to the Comparator of the Object at the relevant column index. My implementation of IDataProvider can also look at my array of column descriptors and generate a list of IColumn objects (needed to construct the DataTable). It's actually a bit more complicated than that (and a work in progress), because I have complicated the above mechanisms to deal with the possibility of a summary row at the end, and when rows are requested, the query string will be recalculated based on form data -- and if it has changed since the last request then the data will be refreshed from the database and the current page set back to 1.

[Wicket-user] trying to understand concept...
I'm trying to wrap my head around how I would create a page where I could either edit an existing record or create a new one.Currently, I've got a form where I can add a record to the database - that part is working great. I'd like to refactor it now to also edit an existing record, if there is one. The user would choose a record from a ListView below the form and the form would be populated w/ the values of that entity bean. The user would change values and then submit the form.
My first idea was to pass the object into the constructor of the page class:public EditProduct(Product editProduct)...and then decide inside the constructor whether or not to create a new Product object or use the one passed in:
//edit or new? Product p = null;if (editProduct == null) p = new Product(); else p = editProduct;I would then pass the Product into the form:
add(new EditProductForm(editProductForm, p));...which would be bound like so: public EditProductForm(String name, Product product) { super(name, new CompoundPropertyModel(product));
..However, I didn't realize you had to do everything within the *default* constructor of the WebPage derived class...oops! I start to see this exception all over again:wicket.markup.MarkupException

Re: [Wicket-user] What about Wicket Javascript and Browser errors?
you cannot add a new component via an ajax call because wicket will not know where to put its markup. via ajax you can only replace components that have been previously renderered.so in your case if you wanted to replace the Label you would do something like this
final Label label;add(label=new Label(a, A));label.setOutputMarkupId
(true); === this is important if you want to rerender this component via ajax
add(new AjaxLink(link) { public void onClick(AjaxRequestTarget ajaxRequestTarget) { Label b = new Label(a,B);
label.getparent().replace(b); ajaxRequestTarget.addComponent
(label); }});-IgorOn 3/15/06, Ayodeji Aladejebi [EMAIL PROTECTED] wrote:

Re: [Wicket-user] DataView (extentions)

Re: [Wicket-user] Newbie question: applying dynamic form component with ListView
Hi Michael,
One thing that I personallythink is important
to understanding ListView is knowing that each item in the ListView is one
concrete model object instance. If you think about it, then you will see
you shouldn't need many(if any) collections in your form backing model
classes. So aListView takes a 'list' ofmodel objects and
displays each one independent of the other. One of the cool things about
wicket is that your model object instancefieldscan be strongly typed
(more easily than Struts). As you'll see in the model object below. Take a
look at the following code which is based on your example (I only used generics
for type clarity):
public class DetailForm extends Form {private final List
ageList = Arrays.asList(new Integer[]
{Integer.valueOf(10), Integer.valueOf(20),
Integer.valueOf(30) });
// You'll probably want to pass your list in to your form
constructor, as opposed to this.private final static
ListDetailModel model = initModelList();
public DetailForm(final String id) {
super(id);
// This model is a list of DetailModelsListView
listView = new ListView("detailList", model) {
public void populateItem(final ListItem listItem) {
listItem.setModel(new
CompoundPropertyModel((DetailModel)
listItem.getModelObject()));
// This is bound to
model.getCode()/setCode()listItem.add(new
TextField("code"));
// Same for
model.getAge()/setAge()listItem.add(new
DropDownChoice("age", ageList));
// Same for
model.getName()/setName()listItem.add(new
TextField("name"));}};add(listView);
}
// Just a test to see that your changes are taking
effect.@Overrideprotected void onSubmit()
{System.out.println(model);}
// Again, not ideal, but for the sake of this example.
private static ListDetailModel initModelList()
{ListDetailModel model = new
ArrayListDetailModel();model.add(new
DetailModel(Integer.valueOf(10), "Harry",
"bigboy"));model.add(new DetailModel(Integer.valueOf(20), "Jan",
"foo"));model.add(new DetailModel(Integer.valueOf(30), "Meg",
"boss"));return model;}
public static class DetailModel implements Serializable {
private Integer age;private String
name;private String code;
public DetailModel() {
}
public DetailModel(Integer age, String name, String code)
{super();this.age =
age;this.name = name;this.code =
code;}
public String getCode() {return
code;}
public void setCode(String code)
{this.code = code;}
public Integer getAge() {return
age;}
public void setAge(Integer age) {this.age
= age;}
public String getName() {return
name;}
public void setName(String name)
{this.name = name;}
@Overridepublic String toString()
{return name + ", " + age + "(" + code +
")";}}
}
Good luck, I hope this helps you understand. Just remember that it
really is as easy as it should be, which (sadly) takes some getting used to if
you've used other frameworks.

Ok its pretty basic but I havent been able to figure out why i am not able to get CompoundPropertyModel work for me.Class BasePage{ Account getAccount( ){ }}Class MyPage extends BasePage{
MyPage(){ Form form = new Form(); form.setModel(new CompoundPropertyModel(this)); form.add(new Label(account.username)); form.add(new PasswordTextField(account.password
)); form.add(new AccountFieldsPanel(accountFields)); }}public class AccountFieldsPanel extends Panel { public AccountFieldsPanel(String id) { super(id);
add(new Label(account.firstName)); add(new Label(account.lastName)); add(new Label(account.email)); add(new Label(account.phone));
}}Fields in the AccountFieldsPanel are showing up blank. The fields in MyPage (account.username account.password) show up just fine. The AccountFieldsPanel is not calling getAccount( ).getFirstName( ) for example - i checked this thro debugger. Account object has all the attributes and it is being picked from the Session. For some reason am not able to get the AccountFieldsPanel to use the MyPage as its Compound model.

you cannot add a new component via an ajax call because wicket will not know where to put its markup. via ajax you can only replace components that have been previously renderered.so in your case if you wanted to replace the Label you would do something like this

label.setOutputMarkupId (true); === this is important if you want to rerender this component via ajax

you cannot add a new component via an ajax call because wicket will not know where to put its markup. via ajax you can only replace components that have been previously renderered.so in your case if you wanted to replace the Label you would do something like this
final Label label;
add(label=new Label(a, A));
label.setOutputMarkupId (true); === this is important if you want to rerender this component via ajax
add(new AjaxLink(link) { public void onClick(AjaxRequestTarget ajaxRequestTarget) { Label b = new Label(a,B);
label.getparent().replace(b);
ajaxRequestTarget.addComponent (label); }});

please please guys what can be wrongisnt it as basic as

Re: [Wicket-user] trying to understand concept...
you cannot call the page standalaone from the browser. wicket doesnt work that way. the /only/ pages you can call yourself are the bookmarkable pages that have a stable url.the ?path... urls are internal and the same url can point to different pages dependent on what the session state is. you should never call those urls directly.

Re: [Wicket-user] Newbie question: applying dynamic form component with ListView
Vincent, I'm not sure I understand your question. The Label objects are used to render some value field of your model object. In my opinion, its easiest to understand the ListView as a black box that takes a list of domain objects, wires up the proper rendering components for the elements you desire to render and outputs the result. The populateItem(ListItem item) method is the 'programmer directions' on how to do this for each element in the list. More simply, populateItem is called for each item in the list.

Re: [Wicket-user] DataView (extensions)
the question was about large datasets, in which case it is not a good idea to keep that stuff in session. but i am glad to see IDataProvider is flexible enough for you to adopt to your usecase.-Igor On 3/15/06, Frank Silbermann [EMAIL PROTECTED] wrote: The DataTable in Wicket Extensions allows for both paging and sorting. The API provides a partial implementation of IDataProvider, i.e. SortableDataProvider, which you can extend – or you can create your own from scratch. There are classes used SortableDataProvider and also available for your own implementations to allow you to record the sorting requests which arrive each time the user clicks the heading of a sortable column in the DataTable. The IDataProvider method "Iterator iterator(int first, int count)" -- which you must implement -- requests one page worth of data rows, specifying where to begin among the set of all rows, and how many are needed for the current page. It is up to the implementer to ensure that the rows returned are sorted according to the history of sort requests. (Presumably, your most recent request dictates the primary sort level, the previous sort request would be the secondary sort level, and so on. For example, if the user clicked the header for first-name and then the header for last-name, the list would be sorted by last-name, but among people with the same last-name they would appear in first-name order.) I believe the creators of DataTable assumed that in the usual case, every invocation of IDataProvider.Iterator(first, count) would result in a new request of rows from the database, and the accumulated sort criteria would be used to build the SQL "ORDER BY" clause. This approach avoids burdening the session storage, but requires lots of database calls. It also requires complex custom code to generate the SQL query command taking into account both the required ORDER BY clause and also to select the proper subset of rows needed for that page only. I suppose if you wrapped the ResultSet in a pageable RowSet and kept that RowSet in session storage, then until the sorting order changed you could use the same RowSet each time a new page is requested. If the RowSet caches the data, then the RowSet will be a huge object in your session storage. If you find a RowSet implementation which reconnects to the database for each subset of rows you request, that might simplify your code without burdening session storage. (Of course, if your RowSet maintained a connection to the database, you'd be tying up a DBConnection – not a good idea.) My problem is to display mostly small result sets containing not raw data but rather statistics, which may be time-consuming for the database to compute. I have about fifty different SQL select queries (not counting variations in the WHERE clause according to parameters chosen by the user). Usually, these results must be presented in tables with sortable columns. This is not an e-commerce application; rather, it provides information to a small group of process engineers. With few users and small result sets, I am not so worried about session storage. With about fifty different DataTables to present -- and I'm not sure we have the _right_ set of queries, either -- I _am_ greatly concerned about flexibility and ease of programming. Therefore, I have chosen to allow the table's data to remain in session storage, re-sorted in memory whenever the user requests, and replaced with new data when the user changes the values of request parameters. The data does not leave session storage until the page containing it expires -- this is clearly not a general approach for every kind of production system. The main advantage is that all I have to do for each table is override the method that generates the SQL SELECT query string, and I can display the results in a DataTable easily configured for sorting and/or paging. (Only a very few of my DataTables are large enough to require paging.) When I'm finished, I'll post my code; even if it's not suitable for most production applications my classes might serve as a useful prototyping tool. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Igor Vaynberg Sent: Wednesday, March 15, 2006 10:59 AM To: wicket-user@lists.sourceforge.net Subject: Re: [Wicket-user] DataView (extentions) I cant speak for Frank's implementation, but when the IDataProvider is implemented correctly you only retrieve the window of data that will be rendered for this request and hold none of it in session. so the performance of the datatable component itself should be great. -Igor On 3/15/06, Mats Norén [EMAIL PROTECTED] wrote: That would be great! btw, how is the performance with large resultsets?

[Wicket-user] Problems migrating my old web application to Wicket
After some reading and experimenting with wicket, I am just trying to collect the steps that would be necessary to migrate an web application (that used XSLT transformations) to wicket. There are several questions that I would like to ask. I surely do not understand Wicket enough, these are all beginner's questions. The main characteristics are: 1. There are ca. 200 static HTML-Pages without any header and navigation elements. They are distributed over several subdirectories, the root being WEBAPP/content. My Question: How can the single root directory for all HTML pages be configured? I found a IResourcePath and WebApplicationPath class, but no usage of it. 2. So far there were several XML pipelines to insert a header block and a navigation block on the left via XSLT transformations. The navigation block has links to all pages in a subdirectory and is the same for all pages in this subdirectory and is defined in a XML file siteindex.xml. Question: Do I really have to write a class for every HTML page? That means about 200 classes that are all nearly the same! They all could extend a common base class and add nothing apart from their classname. I would be happy to write a class per subdirectory that could evaluate the siteindex.xml file and create a dynamic navigation component. This class could even be the same for all pages, if it could be configured. The HTML pages should remain unchanged. There should be no wicket:id in every HTML page for the header and navigation block, this should rather be done outside the pages. Maybe, I could write a XSLT preprocessor stage to achieve that. 3. There will be some Java classes to do real work, some protected pages visible only to registered users and a lot more which I believe Wicket is suited very well for. I hope anyone can give me some hints where to find additional information.

Re: [Wicket-user] validating input
if we want to support this then we don't want a IModel.getObjectType() ofcoursebut a IModel.getObjectType(Component)A model doesn't return one thing for a text field!think about compound models.. So you can't type the IModel itself because that doesn't help if the model can return multiply things.Also getModelObject().getClass() doesn't really work because when you edit for example a new Person()object that returns for its properties all null. Then suddenly types don't work but if they have a property then it works? That looks really inconsistent to me.I guess if we want to support it we need getObjectType(Component) and then walk the complete class property pathBut i am not a big fan of this if i think about it, the developer knows it much better upfront. johanOn 3/15/06, Igor Vaynberg [EMAIL PROTECTED] wrote: but i guess if there wasnt typeerasure we wouldnt have the wildmasks...-Igor On 3/15/06, Igor Vaynberg [EMAIL PROTECTED] wrote: type erasure sucks, dont think generics can help us there. and even if there wasnt type erasure what can you do for IModel? extends SomeClass :) -IgorOn 3/15/06, Eelco Hillenius [EMAIL PROTECTED] wrote: For Wicket 2.0 we might be helped with generics.

A stupid typo on my part. Rather than getPageClass(), I kept writing
getPage().

So if you set the response page to a page instances we can't redirect

a bookmarkable page
When targeting a instance the url must be something like wicket:xxx:0

I did say this for a reason:

so don't do
setResponsePage(new MyPage())

And als we can do a bookmarkable redirect.

Yeah, I did:

Is there a nicer way, perhaps?

Re: [Wicket-user] Newbie question: applying dynamic form component with ListView
mmhh It did struck me for a while to understand the underlying concept of Wicket's model and the relationship with various components. One thing I notice, It seems that Struts deal with form backing model more transparent than Wicket does in terms of accessing the model object (or may be I'm just being bias :). Or perhaps it just the way model 2 was implemented. However I agree in long run Wicket provides better reusability and scalability once I get used to with the concept. Thanks for your thorough explanation I really appreciate it.MichaelJonathan Cone [EMAIL PROTECTED] wrote:Hi Michael, One thing that I personallythink is important to understanding ListView is knowing that each item in the ListView is one concrete model object instance. If you think about it, then you will see you shouldn't need many(if any) collections in your form backing model classes. So aListView takes a 'list' ofmodel objects and displays each one independent of the other. One of the cool things about wicket is that your model object instancefieldscan be strongly typed (more easily than Struts). As you'll see in the model object below.

[Wicket-user] Overriding onRender() for BookmarkablePageLink
This approach used to work for me under 1.1, but no longer in 1.2.
I have a BookmarkablePageLink that I want to disable when its target is
a subclass of a given page.
I used to do something like this:
protected void onRender( final MarkupStream markupStream )
{
setEnabled( ! m_parentClass.isAssignableFrom(
getPage().getClass() ) );
super.onRender( markupStream );
}
But this now throws an exception:
wicket.WicketRuntimeException: Cannot modify component hierarchy during
render phase
at wicket.Page.checkHierarchyChange(Page.java:1001)
at wicket.Page.componentStateChanging(Page.java:934)
at wicket.Component.addStateChange(Component.java:2118)
at wicket.Component.setEnabled(Component.java:1732)
...
How should I go about creating the same effect? Where should I set the link's
enabled value based on the above criterion?
Thanks!

Re: [Wicket-user] Newbie question: applying dynamic form component with ListView
Struts might be more transparent in that it delivers you a flat model.
There's just that request and that one form comming in, and the form
is populated by matching incomming request parameters with formbean
properties. Furthermore, that formbean IS your model (and your only
one), instead of a facade like Wicket's models are. It's surely
simpler in that respect, but quite limited too.

mmhh It did struck me for a while to understand the underlying concept of
Wicket's model and the relationship with various components. One thing I
notice, It seems that Struts deal with form backing model more transparent
than Wicket does in terms of accessing the model object (or may be I'm just
being bias :). Or perhaps it just the way model 2 was implemented.
However I agree in long run Wicket provides better reusability and
scalability once I get used to with the concept.
Thanks for your thorough explanation I really appreciate it.

Hi Michael,
One thing that I personally think is important to understanding ListView is
knowing that each item in the ListView is one concrete model object
instance. If you think about it, then you will see you shouldn't need
many(if any) collections in your form backing model classes. So a ListView
takes a 'list' of model objects and displays each one independent of the
other. One of the cool things about wicket is that your model object
instance fields can be strongly typed (more easily than Struts). As you'll
see in the model object below. Take a look at the following code which is
based on your example (I only used generics for type clarity):
public class DetailForm extends Form {
private final List ageList = Arrays.asList(new Integer[] {
Integer.valueOf(10), Integer.valueOf(20), Integer.valueOf(30) });
// You'll probably want to pass your list in to your form constructor, as

public DetailForm(final String id) {

// This model is a list of DetailModels

public void populateItem(final ListItem listItem) {
listItem.setModel(new CompoundPropertyModel(
(DetailModel) listItem.getModelObject()));
// This is bound to model.getCode()/setCode()
listItem.add(new TextField(code));
// Same for model.getAge()/setAge()
listItem.add(new DropDownChoice(age, ageList));
// Same for model.getName()/setName()
listItem.add(new TextField(name));
}
};
add(listView);
}
// Just a test to see that your changes are taking effect.
@Override
protected void onSubmit() {
System.out.println(model);
}
// Again, not ideal, but for the sake of this example.
private static ListDetailModel initModelList() {
ListDetailModel model = new ArrayListDetailModel();
model.add(new DetailModel(Integer.valueOf(10), Harry, bigboy));
model.add(new DetailModel(Integer.valueOf(20), Jan, foo));
model.add(new DetailModel(Integer.valueOf(30), Meg, boss));
return model;
}
public static class DetailModel implements Serializable {
private Integer age;
private String name;
private String code;
public DetailModel() {

I apologize! The fields on the template were of type 'text'. They were never labels/span.
I changed to wicket.TextField in the Panel and its working fine now. I sdn't be working late i guess :)But normally i have seen wicket complain - about such mismatch. Oh may be its because Label does not have checkComponentTag -

This means that you declared wicket:id=sub-panel in your markup, but that you either did not add the component to your page at all, or that the hierarchy does not match.
