Hibernate uses method calls to get the values of domain class properties by default. How can I configure direct field access with GORM?
It's not directly supported but will be in 1.4. For now you can enable it with a custom Configuration subclass as described at http://grails.1312388.n4.nabble.com/GORM-setting-access-quot-field-quot-td1592837.html#a1594428
I did a small post about subclassing Configuration with links to specific examples at http://burtbeckwith.com/blog/?p=465
I suggest this is due to how groovy implements Beans convention therefore not something that can be configured for GORM.
