Forum OpenACS Q&A: Re: Subsites, Host-Node Map, and Context Bar

I do exactly the same thing but some of my subsites have nothing to do with each other. The context-bar is set in www/default-master.tcl. if you add something like

if { [template::util::is_nil context_bar] } { 
        if { [ad_conn package_key] eq "acs-subsite"  } {
                set subsite_node_id [ad_conn node_id]
        } else {
                set subsite_obj_id [site_node::closest_ancestor_package -node_id [ad_conn node_id]]
                set subsite_node_id [site_node::get_node_id_from_object_id -object_id $subsite_obj_id]
        }
    set context_bar [ad_context_bar -from_node $subsite_node_id ]
}

in place of just setting the context bar it will probably do what you want.
