React/Flux way to handle permission sensitive actions with login flows

Question

I have been playing with React/Flux, and I am having trouble wrapping my head around the \'Flux Way\' for handling permission-sensitive actions.

As FakeRainBrigand suggested in his answer, you'd want to just check that the user has a valid session before creating a comment by first retrieving that value from the SessionStore:

case CommentConstants.ADD_COMMENT:
  if (SessionStore.getUser()) {
   createComment(action.data);
  }
  break;

But to preserve the comment so that it gets created after the user logs in, I would create a collection of pending comments in the CommentStore, and then later, in a callback to the login verification and session creation, dispatch a new action to inform the CommentStore that the user has now logged in. Then the CommentStore can respond to that by creating real comments out of the pending ones.
