In an "ADF Task Flow", i'm trying to use a router to select which page will show base on the result from a query (if empty, page A, else page B).

There is alot option in expression builder of the router.. but not much related to the results of my query?!?

Thanks for your help

Ben

Not exactly your use case, but it should get you started. The key is to execute the vo query first and then check if the iterator returned zero rows or more than zero rows.
