title: Getting publish_actions permission with just a common Post action
body: <p>My Facebook app's permission dialog doesn't ask for publish_actions permission even though I said it should.  I think the reason has to do with not having any Open Graph actions declared.  However, I want to use a common Post action, and common actions don't get declared -- in fact, if you try to create a Post action in Open Graph manually, you get the error: A custom Post action is restricted. Please use the common Post action instead.</p>
  
  <p>What's the solution in order to get the publish_actions permission, if you are only going to use common actions that Facebook predefines?</p>
