could not find implicit value for evidence parameter of type slick.ast.TypedType[(slick.lifted.Rep[Int],...

I'm looking to do something like the following:



streetTable.joinLeft(countQuery).on(_.streetId === _._1).map {
case (_street, _cnt) => (_street.streetId, _cnt.map(_._2 > 0))
}


Where countQuery was defined previously and has two columns, (Int, Int).



I am getting this error in a couple places throughout my code, and it seems like it is happening when I have a subquery (like countQuery) where it is more complex than a simple select (maybe I do a sum or I create a boolean column using the > operator). Then I get the error when I try to do an outer join using that subquery.



Any ideas?
