Lock Version not incrementing

[nikhilbansal]

person = Person.create!(:name => 'xyz') - No validations in the model
Here the _lock_version is 1
person.save
Here the _lock_version is still 1

Am I missing something ? or is this a bug. Using mongo 2.4.13 with mongoid 3

@nikhilbansal Is it possible that since you're not changing any fields, mongoid is not calling update, thus the _lock_version is not incremented? Could you provide a test which breaks?

[nikhilbansal]

@burgalon I ran the spec. And 16 specs out of 38 failed. I have already tried changing the fields, but still doesn't work.

One such case was.
6) Mongoid::OptimisticLocking optimistic locking on a document should allow creating
Failure/Error: person._lock_version.should == 2
expected: 2
got: 1 (using ==)
# ./spec/optimistic_locking_spec.rb:90:in `block (3 levels) in <top (required)>'

@nikhilbansal Specs are passing here with Mongoid 3.

[nikhilbansal]

We are using mongoid 4.0.2
Is that the reason of issue.

[burgalon]

@nikhilbansal Indeed mongoid 4.0.2 seems to break. Can you look into the issue and possibly submit a pull request?

@burgalon I am still getting this issue with mongoid 5.0.2.. Any patch to it?
