Markup inheritance and composition mix
Hi everyone,
I am new to wicket and I am encountering a problem when I am trying to mix
some panel inheritance and composition. I don't know whether I'm doing
something wrong or it is not supposed to work like that but hope you can
help with some advice. So here's my hierarchy :
Panel -> A -> B . This is an inheritance relationship where panel B extends
panel A which extends Panel.
Panel -> C .
If I add panel B and panel C to a page everything works fine.
If I am trying to add panel C to panel B ( bPanelInstance.add(C) ) and add
panel B to the page then I am getting into problems (even if C is an
EmptyPanel instance) :
If I have
[C content]
I get an exception saying that the end tag for panel "b" is missing, though
the end tag is there. Here's a sample of my exception where the name "login"
equates to "b" from my exmaple.
WicketMessage: close tag not found for tag: . Component: [MarkupContainer
[Component id = login]]
Root cause:
org.apache.wicket.markup.MarkupException: close tag not found for tag: .
Component: [MarkupContainer [Component id = login]]
at
org.apache.wicket.markup.html.panel.Panel.onComponentTagBody(Panel.java:123)
at org.apache.wicket.Component.renderComponent(Component.java:2596)
at org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1521)
at org.apache.wicket.Component.render(Component.java:2421)
at org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1399)
at org.apache.wicket.MarkupContainer.renderAll(MarkupContainer.java:1537)
at org.apache.wicket.Page.onRender(Page.java:1522)
at org.apache.wicket.Component.render(Component.java:2421)
at org.apache.wicket.Page.renderPage(Page.java:926)
Adding a panel to another one works fine unless is one of my extended
panels, therefore I guess it's something that I am missing when I am
extending the panels. The way I am extending the panels is standard and only
I only override that required constructor and nothing else.
To summarize :
I have some markup inheritance with panels which works fine. I get the above
error when I am trying to add a panel using Panel's add method to my
extended panels. The html markup it's correct and it's not missing any tags.
Markup inheritance is done in the simplest way by only providing the panel
id constructor.
Do you have any idea why this happens ? If you think it should not happen,
you have tried it, you do not get into this and cannot reproduce the error,
can you provide a simple working example of this scenario ?
I am using Wicket 1.4-rc2.
Thanks very much,
Kind Regards,
Razvan

Hi Igor,
I was hoping I can create the hierarchy in the Index.html page not in the
panel itself, which I might want to reuse in other pages.
The reason I wanted to do it like that is that I want to reuse the B panel
as a panel which always contains a feedback panel along with _random_
forms/panels etc.
Anyway, your argument is fairly decent ... thanks very much for making it
clear.
Regards,
Razvan

in markup for B you dont have a tag with wicket:id="C" so where should
the markup for panel C be rendered?

Hi Igor,
First, thanks answering.
I have posted the demo code that throws this exception in a pastebin here :

its really had to tell whats going on because your markup is being
stripped, why dont you paste it all into a pastebin and send us a link
