Question

I am working on a grails application which uses Amazon’s SimpleDB.
I changed a domain field type from String to boolean and now my application does not start up. We are using jPA plugin for integration.
I have not changed the name of the field just the type.

My code is

String newsletter

change the above to

boolean newsletter = false

It gives me a hibernate exception
