Andreas, I don't know if this will help you or not, but I'm about to
release an updated version of Conditional Tags that will now offer the
<r:puts> tag to render values. My goal was to allow users to inspect
the results of their evaluators but it would be handy here too. You
could create your own extension with a module like:
module MyModule
include ConditionalTags::Evaluatable
evaluator "id", :index_not_permitted do |tag, element_info|
tag.locals.page.id
end
end
Then, in your extension's my_extension.rb file you'd add the following
code to the #activate method:
raise "My Extension requires the Conditional Tags extension to be
loaded first" unless defined?(ConditionalTags)
ConditionalTags::CustomElement.send :include, MyModule
And suddenly you'll be able to output the value you seek using:
<r:puts value_for="id" />
Better still, you would also be able to use 'id' in conditional
statements like:
<r:if cond=" id is 15 ">I know what contextual page I'm on!</r:if>
Don't know if that part would be useful to you or not though.

Hey guys,
I'm not subscribed to the dev mailing list, but anyway...
Sean, could you please add :id to the standard page tags?
[:breadcrumb, :slug, :title, :id].each do |method|
desc %{
Renders the @#{method}@ attribute of the current page.
}
tag method.to_s do |tag|
tag.locals.page.send(method)
end
end
I'm aware that this is a pretty much useless tag for most users and
developers, but in some situations it comes in handy.
Thanks,
Andreas
