ie.

layer="Products.Charlie.skin.ICharlieSkin"

fails for /@@detail.html but
Right. This will look up the 'detail.html' view for (context, request).
Now it depends on what layers the request has applied to. Unless you've
changed anything in the default skin configuration, it will have Zope's
default skin. Since the 'detail.html' view above wasn't registered for
the default layer but for soemthing else, it's not found.
<browser:page
for="Products.Charlie.event.interfaces.IEventDetail"
name="detail.html"
template="detail.pt"
class=".detail.DetailEdit"
permission="cmf.ModifyPortalContent"
/>
is fine with /++skin++charlie/@@detail.html
Yup, because if you don't specificy a layer explicitly, <browser:page />
will register a view for IDefaultBrowserLayer. Your charlie skin
probably inherits from IDefaultBrowserLayer (either directly or
indirectly). That's why this works.
Of course, this ties in with what I get from Zope - that the adapter
can't be found. I suspect I've misunderstood something fundamental on
how views work with layers.
My book has a large section devoted to this. :)
Regarding CMFDefault - all views are registered explicitly for
ICMFDefaultSkin but I think this isn't necessary as this is configured
as the default skin.
No, it *is* necessary, because the default skin can always change. In
fact, nearly every application (in the Zope 3 world) sets the default
skin (otherwise you'd need those hideous ++skin++ things in all URLs).
Also, by explicitly putting all views on the ICMFDefaultSkin layer,
those views are only there if your skin interface inherits from
ICMFDefaultSkin. Which means you can easily "switch off" those CMF views
by not including ICMFDefaultSkin. For some people this is an important
use case.
