Didn’t we solve this issue with your other topic - where I showed you how to render one of two page includes based on whether there was data in the queue model or not?  Shouldn’t you now expect this include page always to have ID data when called? 

(Yes, I’m going back through and cleaning out unanswered topics…)

Um … well … yes…  but … nvm. Can’t think of a use case where a page needing to work based on the id param shouldn’t throw this error. The page would be generally broken anyway.
