[lively-kernel] newbie - "Cannot serialize old model object" problem

[Davide Della Casa]

P.S.

Saving a world starting from the "slide.xhtml" file works just fine - no serialization problems there.

So I guess there is probably something from the default index.xhtml world that is annoying the serializer?

Cheers,
