Cannot generate hibernate mappings from schema

I am trying to get IDEA 12 to generate hibernate (4.1) mappings from schema but it doesnt like it. Every time, regardless of what combination of xml/annotations output, single table selection , etc, I use, it always fails with the error: "basic attribute type should not be object". Then, the OK button is always greyed out meaning I have to close the dialog and start again.

My pom.xml is:

OK - I was being a doofus. I need to expand all the nodes and I would have seen all the red markers. So, once all the red markers were corrected, the mappings were generated BUT it seemed to want to generate mappings for sequences. This resulted in errors when trying to run any query in the hql console. Any help would be appreciated. I havent tried with other databases yet.
