Hi, I gave a quick look at the patch, I think the reason it is not working with MongoDB is that MongoDB does not support natively Character type. You need to use a different CharacterType implementation for MongoDB, you can do it via the method MongoDBDialect.overrideType(...). You will find that we are already doing it for other types like Byte and Calendar for example. You should do the same for Character (and Short I suspect). I have also created a branch where I rebased your work to the latest changes and fixed the checktyle errors (branch 401 on my repository): https://github.com/DavideD/hibernate-ogm/tree/OGM-401 I hope this help, Davide On Mon, Dec 22, 2014 at 10:43 AM, Davide D'Alto <davide(a)hibernate.org&gt; wrote: > > Hi Ajay, > sorry we were quiet in these days, we worked hard for the latest OGM > release and most of us have started the Christmas holidays. > > I'm packing for my holidays as well so I don't think I will be able to > look at this now. > I'll try to have a look at it tomorrow. > > Cheers, > Davide > > > On Mon, Dec 22, 2014 at 2:06 AM, Ajay Bhat <a.ajay.bhat(a)gmail.com&gt; wrote: >> >> Hi, >> I was working on OGM-401 (Implementing new property types) and I >> encountered some errors while running the tests.
