I'm attempting to write an LWRP using the LWRPBase pattern. I'm using the Jenkins cookbook as my example. What I'm bumping into is that if I declare an attribute with the required true, its not actually being enforced. The only examples I can find using this pattern with a required attribute only have it set on the name attribute. In my case I have a couple extra attributes which are also required.

Is this a bug, by design, or might I be doing something wrong? Here is shortened version of what I have

class Chef
  class Resource::MyResource < Resource::LWRPBase
    identity_attr :myid
    provides :my_resource

    self.resource_name = :my_resource

    actions :create, :delete
    default_action :create

    attribute :command, :kind_of => String, :required => true

So I whipped up a test which invokes this as this:

my_resource "blah" do

I was expecting a validation error, but it happily proceeded into my provider code and wrote a file to disk (without the necessary information).

Assuming this is a bug, whats the cleanest/appropriate way for me to enforce the requirement? I understand I can hack up some code to do this, but if there is an existing method or something I can call that does that in a standard way I'd prefer that.
