in java:
page->message
in markup:
page->border->message
so when wicket tries to render message in the markup it cannot find it because it expects it to be in the border, but in fact you have added it to the page itself in extendpage.
so what you should do is either someting like this
ExtendPage() { getBorder().add(message); } to put it in the right place
or
BasPage() { add(new MyBorder("blah").setTransparentResolver(true); } this will tell wicket that the border is transparent - if component inside border cannot be found wicket should try to locate it in the border's parent
or use markup inheritance which is a much much better fit for this usecase

Sorry to send this again, I know you're all very busy trying to get the 1.2 release together, but I didn't want this to fall through the cracks if it is a bug.
I'm get a "WicketMessage: Unable to find component with id 'message'"
error. Maybe this can't be done or I'm doing it wrong using 1.2rc4, but what I'm working with is a MyBorder component, a BasePage, and ExtendPage. Here's the distilled code bits:
MyBorder.html:
<wicket:border>
<div wicket:id="header">[header]</div>
<div>
<wicket:body/>
</div>
<div wicket:id="footer">[footer]</div> </wicket:border>
MyBorder.java:
public class MyBorder extends Border {
public MyBorder(String id) {
super(id);
add(new Label("header", new Model("Border Header")));
add(new Label("footer", new Model("Border Footer")));
}
}
BasePage.html
<html>
<body>
<div wicket:id="border">
<wicket:child/>
</div>
</body>
</html>
BasePage.java
public class BasePage extends WebPage {
public BasePage() {
add(new MyBorder("border"));
}
}
ExtendPage.html:
<wicket:extend>
<span wicket:id="message">[message]</span>
</wicket:extend>
ExtendPage.java:
public class ExtendPage extends BasePage {
public ExtendPage() {
super();
add(new Label("message", new Model("Extended message")));
}
}
Here's the error output minus stack:
<html>
<head>
<title></title>
</head>
<body>
<div wicket:id="border">
<wicket:child><wicket:extend>
<span wicket:id="message">[message]</span>
</wicket:extend></wicket:child>
</div>
</body>
</html>
[Page class = ExtendPage, id = 4]:
# Path Size Type Model Object
1 _<body> 2.7K wicket.markup.html.internal.HtmlBodyContainer
2 _header 473 bytes wicket.markup.html.internal.HtmlHeaderContainer
3 border 1.3K com.ses.wicket.components.test.x.MyBorder
4 border:_child 485 bytes wicket.markup.html.WebMarkupContainer

7 border:header 456 bytes wicket.markup.html.basic.Label Border Header
8 message 460 bytes wicket.markup.html.basic.Label Extended message
From this it looks like the "message" Label isn't being added to the correct component(border:_child:_extend?), am I doing something wrong, or is this a bug?
Thanks for any input!
