This is a known bug, and we already had a fix pending review: https://issues.apache.org/jira/browse/CAY-2070 https://github.com/apache/cayenne/pull/92
So I did just that. It fixes the problem in my tests. Also note that it explicitly disables sync button for subentities, as it can't be made to work reliably with the current mapping approach. In the future (probably past 4.0) we are planning to allow setting an explicit root table for each v-inheritance subentitity, making sync possible again. Let me know if you need help with doing a fresh build of CayenneModeler from master. Such an upgrade will be a bit invasive though, as it bumps up the version of project XML, and will make your projects incompatible with earlier modeler versions.
