I am including both these errors in one post, because I have a hunch
they are related. If it was a mistake to do so even if they were
related, please let me know for future reference.
I am working with OCM, I have a single class that is being stored and
versioned in the repository (see below). My first error is when I try to
get an instance of this class by version (it works fine if I do just a
getObject (path) ). The error is the IncorrectPersistentClassException
due to no descriptor for nt:unstructured, which I don't think I am
using. If I do need this, why? And how should I define it?
I also have an error when I try to checkin the object after updating
(checkout, getObject, modify it, update, save appear to work fine.). The
error is the RepositoryException caused by NoSuchItemStateException. I
have included what I think is the relevant information below. Using
Jackrabbit 1.4 with 1.4.2 core. I would certainly appreciate any input -
on either error.
