Re: Incomplete ChangeMap passed to CommitLogListener

Hi Nikita,

sorry for the late reply, managed to miss a new post in my cayenne mail =
folder.
What I didn't miss was the merge that just happened on STABLE-4.2 :).

Just tried it out and from trying it on at least my test project, the =
fix works great =E2=80=94 so huge thanks!

Cheers,
- hugi
