--------------------------------------------------------------
Is this going to be implemented or 1.5-M2 is just a synonymous with "we will
set it to 1.6 when 1.5 is near"? It's been almost three years since the issue
was created. Just to remind, there was a very long discussion about that. I
provide links to the most important thoughts.

going back to C "as I can achieve everything from Java in C and get better
performance". ;)

- summary.
Even Open Power Template for PHP has got such a feature.

If you are not going to implement this please tell me if there are any easy
ways to achieve this. I haven't found anything in docs; the mailing discussion
shows only one correct solution but it doesn't look good (messing with
onRenders, initializations, etc.).

> Multiple abstract/implement tags instead of child/extend

> Key: WICKET-1134
> URL: https://issues.apache.org/jira/browse/WICKET-1134
> Project: Wicket
> Issue Type: New Feature
> Components: wicket
> Affects Versions: 1.3.0-rc1
> Reporter: Stefan Fussenegger
> Assignee: Johan Compagner
> Priority: Minor
> Fix For: 1.5-M2
>
> Attachments: wicket-1134.patch, wicket-abstract-implement.patch
>
>
> The current implementation of wicket:child and wicket:extend only allows for
> a single extension per subpage. However, this restriction is neither mandated
> by java class hierarchy nor by any other reason. Therefore, it should be
> possible to extend the current implementation to support multiple 'abstract'
> sections, just like abstract methods in java classes. This could be done by
> replacing
> <wicket:child>
> <wicket:extend>
> some content
> </wicket:extend>
> </wicket:child>
> with
> <wicket:abstract id="foo">
> <wicket:implement id="foo">
> some content
> </wicket:extend>
> </wicket:child>
> (new names have been suggested in
> http://www.nabble.com/Multiple-%3Cwicket%3Achild--%3E-tags-on-a-single-base-page--tf4738673.html)
> A possible application is a layout with two columns, e.g. a header with
> navigation, a left column with sub-navigation and a right column with content
> (where the sub-navigation may change depending on the section. In deed, this
> is already possible using panels or similar means. However, it would allow to
> take advantage of markup inheritance only:
> BasePage extens WebPage:
> <div wicket:id="links>[some nav links here]</div>
> <div><wicket:abstract id="subNavigation">[left navigation goes
> here]</wicket:abstract></div>
> <div><wicket:abstract id="content">[content goes here]</wicket:abstract</div>
> SectionPage extends BasePage:
> <wicket:implement id="subNavigation">[sub navigation links
> here]</wicket:implement>
> FooPage extends SectionPage:
> <wicket:implement id="content">[content goes here]</wicket:implement>
