Hi Andreas,

   I'm afraid I don't know Scala.  Can you give a description of what you are
hoping for.

   We don't have converters on xToOne relationships, but I am trying to figure
out if there is something we can do in our event framework to deal with the issue.

 

Scala's Option is a bit like JAVA8's Optional (http://download.java.net/jdk8/docs/api/java/util/Optional.html) and is a container which may hold a value.

 

It would be very cool if one could write (with JAVA8's Optional):

 

@ManyToOne

private Optional<Project> project = Optional.empty()

 

This way one won't have to care about null-reference.
