Using indices to select actions is not very future proof. If actions are re-ordered or removed this code would have to be changed or it could have potentially tragic consequences. The action name is usually a unique identifier. Afaik the Playlist actions generated from a PlaylistProvider::playlistActions() do not have names. So perhaps you could assign names to them and use those names to choose the right action. Make sure when you fetch the action by name, the action is non-null.
