Error while checking frozen types

[José Guilherme Vanz]

Hi!

I'm developing a scala application using the java driver. In runtime an exception is thrown.
The source code line with problem and the stacktrace can be view here:

Have you ever seen some similiar problem in a scala application? What's my mistake?

Thank you

Hi,

The type checker resolves latitude as type Any because of the null. In the Java world this resolves to Object, the driver doesn't know how to map that. I think you need to specify the type explicitly.

scala> var foo = Some(1.0) match { case Some(d) => d case _ => null }

foo: Any = 1.0

scala> var foo:java.lang.Double = Some(1.0) match { case Some(d) => d case _ => null }

foo: Double = 1.0
