Hi Michael, thanks for an honest attempt to convince me. Hard sell, though. :)
I use a lot of 3rd party libraries and I've only hit one time where using the bean spec was necessary — JasperReports. That was easily fixed by providing *BeanInfo classes, in accordance with the Bean spec. But Cayenne doesn't really follow the Java Bean Spec, it just hardcodes "is", "get" and "set". As for the Eclipse thing… Well. A standard DataObject already has five methods prefixed with "get" so that list is questionable. And I don't miss this functionality. I think it's important to note that the change I'm proposing would not affect those who choose to add the prefix. It just accommodates those of us who choose not to, thus expanding the audience of the framework.
