Require using sls fails

README.md

I'm attempting to have a state depend on another state (state 'chaining' as outlined here)

In my example I have an include for the 'php' formula.

On line 14 of init.sls you can see - sls: php which is supposed to ensure that state install-pear depends on the php state which is derived from php.init.sls (included below for clarity).

When I execute salt foo state.highstate test=True I receive the following:

foo:
----------
          ID: php
    Function: pkg.installed
        Name: php5
      Result: None

The interesting thing is when I change the require to 'pkg: php' it works as I would expect:

foo:
----------
          ID: php
    Function: pkg.installed
        Name: php5
      Result: None

This is a trivialised example, I don't actually want to have a requirement for 'php', I'm actually attempting to chain states in a formula for freepbx I'm working on.

init.sls

include:
  - php

install-pear:
  cmd.run:
    - name: |
        pear uninstall db
        pear install db-{{ salt['pillar.get']('pear-db:version', '1.7.14') }}
    - cwd: /tmp
    - shell: /bin/bash
    - timeout: 300
    - unless: test `pear info db | fgrep 'Release Version' | grep -o -E '[0-9\.]+'` = {{ salt['pillar.get']('pear-db:version', '1.7.14') }}
    - require:
      - sls: php

php.init.sls

{% from "php/map.jinja" import php with context %}

{% if grains['os_family']=="Debian" %}
{% set use_ppa        = salt['pillar.get']('php:use_ppa', none) %}
{% if use_ppa is not none %}

{% set ppa_name        = salt['pillar.get']('php:ppa_name', 'ondrej/php5') %}

php54:
    pkgrepo.managed:
        - ppa: {{ ppa_name }}
    pkg.latest:
        - name: php5
        - refresh: True
{% endif %}
{% endif %}

php:
  pkg.installed:
    - name: {{ php.php_pkg }}
