Subject Re: Versioning with Jcrom
Date Tue, 22 Apr 2008 15:18:20 GMT

Sorry for the late reply.
This was indeed a bug in JCROM, as per this issue:

I've fixed this in release 1.3 which should be out in the coming weeks. In
1.3 you will not need to use the mixin type String array in the DAO. For a
full list of changes in 1.3, see here:

In the future, please post any JCROM related questions on the JCROM user
list at http://groups.google.com/group/jcrom, as I monitor that list much
more closely and will be faster to respond.

Thanks for using JCROM!
