I believe I am doing #1 now with no luck. Let me know if this is
correct:
class Cars {
// ...
object locationQuery extends RequestVar[Box[LocationQuery]](Empty)
def search(xhtml: NodeSeq): NodeSeq = {
def processSearch() = {
// ...
val lq = new LocationQuery(validPickupDate.open_!,
validDropoffDate.open_!, city, city)
S.redirectTo("/select", () => { locationQuery(Full(lq));
requestReference(Full(requestRef)) })
}
// binds are here
}
def selectedLocation(xhtml: NodeSeq): NodeSeq = {
if (locationQuery.isDefined) {
val selectedCity = locationQuery.open_!.pickupLocation
Text(selectedCity.name + ", " + selectedCity.region)
} else {
Text("")
}
}
// ...
}
Thanks,
Bryan
