Max and Andi,

Thanks, that was it. And with that addition the new notification syntax works as well. I'm going to update the wiki; this seems like a critical thing to know when writing an LWRP.

Thanks again,
Kevin Christen

As far as I understand correctly you did not mark you resource as updated. You have to do that in order to enforce notification to be sent

@new_resource.updated_by_last_action(true)

Jake,

Thanks for the quick response, but unless I misunderstand the ticket, that's not my problem. I changed my recipe to use the old-style notification syntax:

ruby_block "the_observer" do
  block do
    Chef::Log.info("the observer has been notified")
  end
  action :nothing
end

package "my_package" do
  provider :test_my_package
  action :install
  notifies :create, resources(:ruby_block => "the_observer")
end

and the results are the same: no notification is sent to "the_observer". Other ideas?

Thanks,
Kevin Christen

Kevin,

  I suspect you're hitting this bug:
