it sounds like iframes are like frames. if that's the case, eelco has
described what you should do.

Hi,
i'm not really following the iframes thing (maybe partly because i
don't know what one is), but pages were certainly not designed to be
nested. pages are containers and so you might be able to nest them,
but i've never tried this and i don't think should be supported
behavior. instead, why not make your own "page" class that inherits
from WebMarkupContainer called something like MyPage or something
and then you can nest these anyway you like. when you have one at
the top level, you can put it inside a WebPage. otherwise you can
do this iframe
iframes are used for showing pages as part of other pages. The
contents of iframes are loaded by a separate request done by the web
browser. This doesn't mean nesting in all cases, because an iframe
can show things not related to the main page. But it can be used to
build nested pages as well, where the embedded pages are managed by
and nested in the containing page. This is what I want to achieve.
It seems as this could work without any major troubles right now, if
Page/WebPage could be given a custom id and thus could act like a
WebComponent. It could add a src attribute to iframe-tags with
matching wicket:id. This would get the browser loading the page from
the right location without any need to bother about the urls involved
to view the nested page.
Unfortunately this can't be achieved easily by subclassing WebPage,
because the id-constructor is gone with Page and doRender() is final
for WebPage. Subclassing WebMarkupContainer doesn't feel right as
well, because this means losing all of the Page/WebPage behavior.
I don't know if this is worth of being supported behavior. But
iframes/frames are a common web technique. They are a bit despised,
but there are a lot of reasonable use cases for them. So maybe it
would be worth supporting them in a way which feels more like Wicket :)
