Jerry,
the wiki has an example:

with markup inheritance you wouldnt need a separate border that wraps all
the pages, simply move everything that is in the border into the basepage
instead.

Thanks for the reply Igor! I'll try the methods you mentioned. You
also
said markup inheritance is a better fit for this use case, could
demonstrate
how you would do this? I thought I was using markup inheritance, but it
appears I don't fully understand how to set it up correctly. Thanks!

*Subject:* Re: [Wicket-user] Border and markup inheritance problem
if you look at the hierarchy of your message label it is like this:
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

Border Footer
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!
