Hibernate Generate Persistence Mappings does incomplete job, and no err msg

In generate mappings dialog, I selected two tables "Customer", then the dialog said I was missing Customer_Permission. So I added that one. It then told me I was missing Permission, so I added that one. Then I clicked OK.

The end result: the first two tables were generated and the third was not. Actually, there were some more tables. All told 5 were generated out of 9 that I selected.

So.. if the dialog even goes so far as to tell me (correctly!) about the missing tables , why can't it get the mapping generation right??

Also, no error messages are displayed to the screen. Is there somewhere else i should look for error messages?
