I'm using latest version of IDEA Ultimate 2016.2.1 (downloaded on August 5) and while attempting to generate a Hibernate persistence mapping, the Import Database Schema wizard is flagging all UUID data types as errors, "'Basic' attribute type should not be 'Object'".
I can work around the issue painfully by selecting java.io.Serializable as the alternate type, generating the mapping, and manually replacing all affected field types back to UUID. However, I'm not certain if this is the best way to work around the problem.
There were earlier problems with the wizard dealing with nvarchar and other PostgreSQL types. Was the UUID tested?
Thanks in advance.
