Subject Re: Removing a version
Date Fri, 18 Nov 2005 17:23:52 GMT
Hi Nicolas,

 I didn't try your code but I think it throws
ReferentialIntegrityException because you are trying to remove the
base version which is referenced by the versioned node.

see http://thread.gmane.org/gmane.comp.apache.jackrabbit.devel/3746

br,
edgar
