Hi Andrea,
It looks like you've stumbled on a bug in NestableJsonFacet. I
clearly wasn't thinking about Date stats when I first wrote it; it
looks like it doesn't detect/parse them correctly in the current
iteration. I'll try to fix this in a subsequent release. But in the
meantime, unfortunately your only option is to use the NamedList
structures directly to retrieve the stat value.
Thanks for bringing it to our attention.
Best,
Jason
