Re: weird "Unable to find component with id"
Hi Thorsten, Thanks for your comments. Weird thing is it only happens rarely in production. I have tried to reproduce this locally simulating random user access with no success.

Hi Martin, Thanks for your answer.

It's weird because: 1- There is no business related exception and I looked at wicket code and nothing seems to be catching/swallowing any exceptions. It looks as if for some weird reason wicket is at that moment not able find "main" on the markup associated to page. 2- This page is called around 500/600 times per day and in two week this happened 16 times. So it must be some extreme edge case... (e.g. first time after a redeployment?) Additional info: 1- On March 14th we jumped from 6.20.0 to 6.22.0. This feature was "there" but was not activated. 2- On May 4th those errors started to happen (and around the same time feature was activated). So we don't know for sure if this is 6.22.0 related or not. I was looking at changes from 6.20.0 to 6.22.0 and at first sight I could no spot anything suspicious. Anyway, we have migrated project to 7.3 and we probably will start using it next week. I will report back any issues I find :-) Thanks again! -- Regards - Ernesto Reinaldo Barreiro
Re: weird "Unable to find component with id"
Hi Ernesto, Does this page use variations/style, e.g. ReplyToProjectRequestPage_custom.html ? It could be that some user uses this custom variation and you test with the default version.

I often have problems with an error message like yours, not with the strange ids though, during development, if I e.g. change markup and just reload a formerly working page in the browser instead of requesting a new and/or restarting Tomcat. So if your customer is not changing markup, he maybe has customers accessing old versions of pages referencing things in markup which don't exist anymore because of upgrades and such.

RE: Misunderstanding : Unable to find component with id 'phl' or A child with id 'phl' already exists:
The ajout method is a debug method.
The main objective is that the method
HeadersToolbar//HeadersToolbar(final DataTable/RefreshingView>//Iterator>>//populateItem(Item> item)
is able to modify the content of "getheader" that is the X1 object (X1 is a for
debug).
In case 1 - I use "ajout" and wicket says phl already exists in the X1 object.
OK, I agree. X1 has already 2 labels.
In case 2 - I use "ajout", but the phl label is not yet declared in the java
object (ajout must add it), but the wicket render says
"Sorry, phl label does not exists".
This means that I cannot modify the getheader object from HeadersToolbar.
The example set the sortable link to the global header object. But I want to
put the sortable link to part of the header object.

PHL,
I'm sorry but it's hard to understand what your are trying to do.
Anyway, I find the X1 class very strange. I think you simply need to remove
the "ajout" method as the label is already added in the constructor. You
cannot add a label several times on the same panel unless you are using a
repeater.
public class X1 extends Panel
{
public X1(String id, String ColumnTilte)
{
super(id) ;
lbl = new Label("labelx", ColumnTilte) ;
add(lbl) ;
add(new Label("phl","added by constructor")) ;

public Label getLabel() { return lbl ; }

Misunderstanding : Unable to find component with id 'phl' or A child with id 'phl' already exists:
Hello,
I try to modify the header of a table. So according to the advice of this
mailing list, I write
public class DataTableFilterToolbarPage extends WebPage
{
/**
* constructor
*/
public DataTableFilterToolbarPage()
{
List> columns = new ArrayList>();
columns.add(new PropertyColumn(new
Model("ID"), "id")
{ private static final long serialVersionUID = 1L;
@Override
public Component getHeader(final String componentId)
{ X1 x = new X1(componentId,"id") ; // My own panel instead of a
label
return x;
}
});
As I want to set the sortable link in a part of X1, I modify HeadersToolbar
public HeadersToolbar(final DataTable table, final
ISortStateLocator stateLocator)
{
super(table);
RefreshingView> headers = new RefreshingView>("headers")
{
private static final long serialVersionUID = 1L;
@Override
protected Iterator>> getItemModels()
@Override
protected void populateItem(Item> item)
{
if (column.isSortable())
{
header = newSortableHeader("header",
column.getSortProperty(), stateLocator);
}
else
{
header = new WebMarkupContainer("header");
}
if (column instanceof IStyledColumn)
{ }
item.add(header);
item.setRenderBodyOnly(true)
((X1)column.getHeader("panel")).ajout() ; // action on X1
header.add(column.getHeader("panel"));
Where X1 is
public class X1 extends Panel
{
public X1(String id, String ColumnTilte) //, TextField x)
{
super(id) ;
lbl = new Label("labelx", ColumnTilte) ;
add(lbl) ;
}
public Label getLabel() { return lbl ; }
public void ajout()
{
add(new Label("phl","added by headersTools")) ;
}
}
Run this code, I get
Unexpected RuntimeException
Last cause: Unable to find component with id 'phl' in [X1 [Component id =
panel]]
Expected:
'filterForm:tableWithFilterForm:topToolbars:toolbars:3:headers:1:header:panel:phl'.
Found with similar names: ''
Markup
The problem is in
"file:/home/phl/apache-tomcat-7.0.47/webapps/phlwick/WEB-INF/classes/xxx/X1.html":
http://wicket.apache.org";>
1
The Title of the column
goes here
Action from HeadersTools goes here
I was expecting that the action ((X1)column.getHeader("panel")).ajout() ; will
define phl in X1
If I change the X.java to
public class X1 extends Panel
{
public X1(String id, String ColumnTilte) //, TextField x)
{
super(id) ;
lbl = new Label("labelx", ColumnTilte) ;
add(lbl) ;
add(new Label("phl","added by constructor")) ;
}
public Label getLabel() { return lbl ; }
public void ajout()
{
add(new Label("phl","added by headersTools")) ;
}
}
So I don't understand why the some time the id phl is not declared and sometime
is it already declared.
This is probably due to the fact that I don't clearly understand the render
mechanism.
Pointers or ideas are welcome.
Thanks,
PHL.
Then I get :
Last cause: A child with id 'phl' already exists:
[X1 [Component id = panel]]
WicketMessage: Error attaching this container for rendering: [HeadersToolbar

Re: Avoiding 'WicketMessage: Unable to find component with id' error
You should add the listView right away and keep it invisible until a
search result is available.

Avoiding 'WicketMessage: Unable to find component with id' error
Im a wicket newbie ..
I have a Search Page with some search criteria inputs and below it, the list
of data based on search.
The first time the page is hit, the listView component is not still present,
because Im adding that only onSubmit() -- like this:
class XPage extends WebPage {
class XForm extends Form {
...
@Override public void onSubmit() {
List resultList = searchDao.search(searchOptions);
add(new ListView ("listView", resultList ) {
});
}
}
The html is straightforward..
...
Even at first hit of the page, wicket shows up the message "Unable to find
component with id listView" ..
Is there a way to make Wicket not worry about unfound components or is there
any other standard way of handling it ?
Appreciate any help...

Re: "Unable to find component with id"
Hi, All
I found out the solution:
Wicket is very strict with the hierarchy. If I define the markup this way:
then I have to create components that way:
BookmarkablePageLink link=new BookmarkablePageLink("link", clas,
new PageParameters("id=" + element.getId()));
link.add(new Label("label", element.getLabel()));
item.add(link);
so the component hierarchy must match.
Thanks to everybody.

Re: "Unable to find component with id"
1. you are repeating the UL tag instead of the LI tag. You should use
, but I'd recommend to rename the component to
menuitem to make it more clear
2. you don't have child components defined in the markup for each
element. This is necessary.
and in your populateItem:
link = new BookmarkablePageLink("link", ...);
item.add(link);
link.add(new Label("label", ));

It seems that there is some kind of fromatting in place which is confused
because of my code fragments.
I've just read the help.
So, the mapping between components:
-- MenuView view = new MenuView("menu", menu);
add(view); // in HeaderPanel.java
-- item.add(new BookmarkablePageLink("link", clas, new PageParameters("id="
+ element.getId(; // in MenuView.java
-- item.add(new Label("label", element.getLabel())); // in MenuView.java

I think, there is a mutual mapping between html and java.
-- MenuView view = new MenuView("menu", menu);
add(view); // in HeaderPanel.java
-- item.add(new BookmarkablePageLink("link", clas, new PageParameters("id="

Re: "Unable to find component with id"
Send the code for HomePage.html and HomePage.html. It looks like you
declaring the label in the markup incongruent to your page hierarchy;
make sure it's in the wicket tag "menu".
Cheers,

Re: "Unable to find component with id"
That can't be the markup that generated that error because there is no tag in
it with a wicket:id="label" which the error message is complaining about.
But you also do not add a tag for exampleTitle which you add here
add(new Label("exampleTitle", exampleTitle));
Basically, every wicket:id in your html files must have a component in your
java file and visa versa

"Unable to find component with id"
Hi
I'm new in wicket. I tried to display a list of components, but I get the
following error:
WicketMessage: Unable to find component with id 'label' in [MarkupContainer
[Component id = link, page = com.myapp.wicket.HomePage, path =
0:mainNavigation:menu:0:link.BookmarkablePageLink, isVisible = true,
isVersioned = true]]. This means that you declared wicket:id=label in your
markup, but that you either did not add the component to your page at all,
or that the hierarchy does not match.
[markup =
