SEAM-GEN Entities and the issue of BOOLEAN type fields

Hello Everyone,

I'm experiencing a strange issue with Seam-Gen after generating the Seam entities from a database with 3 tables (using JBoss Developer Studio ver: 2.0.0.CR2). Any entity/table with BOOLEAN type field throws validation errors (length must be between 0 and 1) no matter what AND even if I comment out that input boolean field (from front end) just to test that I can save it. I get this error from the console: 21:19:01,489 ERROR ContainerBase Servlet.service() for servlet Faces Servlet threw exception. The only time I do not have any issues with saving via the Seam generated CRUD form is if it is saving to a table that does not have any BOOLEAN fields?

I SEAM-GEN'ed from a postgresql database v8.4, has anyone else encountered these issues? If so did you find a solution? Or do I have to make sure that when I design my database(s) that I don't use boolean type columns?

Example javabean found in code section below which is mapped to the database

Thanks,
