This is not exactly a question, it's rather a report on how I solved an issue with write_attribute when the attribute is an object, on Rails' Active Record.

I hooked a HibernateDirtyCheckInterceptor (extends EmptyInterceptor) into the Spring config file. This part is working, as my log entries get posted. My entity class clearly defines itself as not dirty, and the fi...
