Hi Jens,
I was just working on tackling this issue again as I never got it going. I
was hoping you could shed some light into how I could fetch a deleted
document and recover its data. I see in the raw db.sqlite file that the
JSON data is there for the document, but it's marked as deleted. If I ask
the document for its current revision, it comes back nil. I thought I
might be able to get the current revision and then set the isDeleted flag
to false or create a new revision that's not deleted and give it the
properties from the deleted revision.
Is this possible?
Thanks,
Brendan
