[chef] LWRP and new_resource.updated_by_last_action

[< >]

I'm trying to get my LWRP resource - which just a collection of other 
resources
- to tell it's "invoker" that it changed. The invoker does this:

ruby_block "display_changed" do
        action :nothing
        block do
                Chef::Log.info "RESOURCE CHANGED!!!!!"
        end
end

myresource "myresource_name" do
        action :install
        version "360"
        notifies :create, resources(:ruby_block => "display_changed"),
:immediately
end

if, in the "myresource" provider :install action I do a direct
new_resource.updated_by_last_action(true), then the "display_changed"
ruby_block does get executed BUT before all the LWRP resources get processed.

If however I do THIS in the provider;


        ruby_block "set_changed" do
                action :nothing
                block do
                        new_resource.updated_by_last_action(true)
                        Chef::Log.info "PROVIDER CHANGED!!!!!"
                end
        end

        execute "install_component" do
                command "tar --no-same-owner -xzf #{component_local_archive}"
                cwd "#{component_path}"
                user "#{component_owner}"
                group "#{component_group}"
                not_if "test -d {component_path}/bin"
                notifies :create, resources(:ruby_block => "set_changed"),
:immediately
        end

        ruby_block "display_changed" do
                block do
                        Chef::Log.info "CHANGED =
#{new_resource.updated_by_last_action?}"
                end
        end

and {component_path}/bin does not exist, then "set_changed" gets executed and
display_changed displays "CHANGED = true" (i.e. business as expected) BUT the
"invoking resource" does NOT see the change.

if {component_path}/bin does exist then "set_changed" does not get executed 
and
display_changed displays "CHANGED = false" i.e. business as expected.

Any way out of this?
