Hey Seb,

I'd go with an exception which can be handled. You could perhaps have an error route for it and have the choice of either forwarding to a view or returning json as a response to the calling client.

Hi All,
In the scope of https://issues.jboss.org/browse/AEROGEAR-803 , we have a method to retrieve an user (based on its id). If the user don't exist it returns null.

There were some suggestions to change that into :
- throwing a runtime exception (seems a bit brutal)
- or returning an empty user (can be confusing)

What is your opinion about this ?

Seb
