It's with Al Maw's earlier mail. We should consider whether/ where we can integrate this functionality in existing parts instead of bluntly copying it though. I haven't looked into it yet.

Re: [Wicket-user] CSS background images
As you don't have to pre-register packaged resources anymore, you can
reference them if you know the URL, which for such resources always
has the same form:
/webapp/servletname/resources/some.package.SomeClass/theme.css
and even
/webapp/servletname/resources/some.package.SomeClass/some/sub/dir/theme.css
for *unmounted* packages. SomeClass is then used as the class relative
to the loading.
Also, you can use RequestCycle's urlFor and classes of
wicket.extensions.util.resource to do the trick without depending on
Wicket's internals too much. For instance with:
Map m = new HashMap();
RequestCycle r = RequestCycle.get();
m.put(star1, r.urlFor(new PackageResourceReference(StarPanel.class,
star1.gif)));
add(TextTemplateHeaderContributor.forCss(SomeClass.class, theme.css,
Model.valueOf(m)));
and in theme.css all ${star1} will be replaced by that image.
Still a lot of work though, so like Igor said, it would be nice to
have something simpler even. One of the starting points for this might
be TextTemplateHeaderContributor.forCss or CssTemplate it depends on.
CssTemplate could (optionally) parse the body of that file - it's
doing that for the var subst anyway - and replace urls and such.
Contribution is welcome :)
Btw, I'm about to move that package to core for 2.0 (so it looses the
extensions part in the package for that version).

Re: [Wicket-user] CSS background images
i think in this case we are talking about a contextpathprepender but for the css, not just a variable interpolator.also while the texttemplate stuff works what it does is sinclude the css into the page, im talking about a resource so you can have all this stuff done once and served/cached through the normal link/ tag.
