Juergen Donnerstag updated WICKET-1134:
---------------------------------------
Attachment: wicket-1134.patch
Small update on this one:
- generified the patch
- minor bug fixing
But not working properly: 3 tests failing
The ability to have multiple "implementations" identified by an "id" attribute
in derived classes obviously is not yet implemented
No test cases yet for new features
> Multiple abstract/implement tags instead of child/extend
> --------------------------------------------------------

> 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>
