Getting error ORA-00904: "THIS_". on model

[rsearls]

I am wiring 2 pre existing (hibernate) model classes to my Gails 1.3 app.
I get this error on both model classes. Interestingly in both cases the
error is flagged on the last column in each table.

How can I resolve this?

Here is one error msg in full and corresponding model class.

Bizarre. The SQL looks fine. Does this Hibernate model works fine in other apps? It looks like a Hibernate/Oracle issue rather than anything specific to Grails. Perhaps a difference in Hibernate versions, JDBC driver or something else.

Did you try running the SQL above (from the stack trace) in Oracle? My guess would be that product_name isn't the actual name of the field in the table/view you're working with. Perhaps its aliased as something else.
