Hmmm ... the code seems to be fine (as far as I can tell from the code
snippet)
Can you perhaps declare your RequestVars outside of Cars scope?
just
object locationQuery extends RequestVar[Box[LocationQuery]](Empty)
class Cars {
...
}
.. personally I would avoid using open_! unless I'm really sure that
the Box is not Empty.
