To make things a little clearer.
Here a small example, which does not work as it is supposed to do at least
for my understanding.
public class FormBorder extends Border
{
private Form form;
public FormBorder( final String id )
{
super( id );
super.add( form = new Form( "form" ) );
}
public MarkupContainer add( final Component child )
{
form.add( child );
return this;
}
}
<wicket:border>
<form wicket:id="form">
<wicket:body/>
</form>
</wicket:border>
------------------------------------------------------
public class HomePage extends WebPage
{
private Border formBorder;
public HomePage()
{
add( formBorder = new FormBorder( "border" ) );
formBorder.add( new TextField( "name" ) );
}
}
<html>
<body>
<span wicket:id="border">
<input type="text" wicket:id="name">
</span>
</body>
</html>
I get: wicket.markup.MarkupException: Unable to find component with id
'name' in [MarkupContainer [Component id = border, ...
Why does Wicket try to lookup the input field in the border component and
not in the form?
I was expecting that the <wicket:body/> tag would be replaced with the input
field.
Is this a bug, or am I missing something?

Betreff: AW: [Wicket-user] Component nesting problem (bug???)
The code is based on the navmenu example. What we need is a tabbed pane,
where each tab
contains a form.
All tabs extends this class.
public abstract class AbstractTabsPage extends PageWithMenu
{
private Form form;
public AbstractTabsPage(final PageParameters parameters)
{
super();
this.form = new Form( "tabForm" );
add( this.form );
}
public void addToForm( final Component child )
{
this.form.add( child );
}
public String getVariation()
{
return getRequestCycle().getRequest().getParameter( "page" );
}
}
A page looks e.g. like this:
public class TabsPage extends AbstractTabsPage
{
/**
* Constructor.
* @param parameters Page parameters
*/
public Home(final PageParameters parameters)
{
super( parameters );
Login login = new Login();
addToForm( new TextField( "name", new PropertyModel( login,
"name" ) ) );
addToForm( new TextField( "firstname", new PropertyModel( login,
"firstname" ) ) );
}
...
..
.
What's wrong with this code?
Thanks.

What does the rest of your code look like/ how do you add the inputs
to the form to the border?
