Any reason not to use metaClass on domain objects? as in
domainObjectInstance.metaClass.dynamicTransientGreeting = “Hello”
Will this mess with hibernate at all?
It won’t mess with Hibernate at all since it won’t be seen by Hibernate. GORM only maps “real” properties to Hibernate properties.
That’s why the
idandversioncolumns and the collections that are generated fromhasManydeclarations (e.g. theuserscollection generated bystatic hasMany = [users: User]are added to the actual bytecode using an AST. If they were added just to the MetaClass they wouldn’t be seen and wouldn’t be persistent.
