I've been using Skipper for years now, but always with concrete classes.
We've inherited a project which has used annotations and we're very keen to migrate this to a Skipper model.
We have an abstract class AbstractInvite which has (let's say) and id and a name
We then have two super-classes
class ParticipantInvite extends AbstractInvite
class PublicInvite extends AbstractInvite
I can't for the life of me work out how to represent AbstractInvite in Skipper so that the two super-classes will inherit from it.
When I create AbstractInvite in Skipper it creates the class as a concrete class rather than an abstract class...
I'm sure this is my stupidity, but how should this be drawn in Skipper?
