There are three classes,for example,ClassA,ClassB and ClassC

@Entity(name = "ClassA")
public class ClassA implements java.io.Serializable {
private static final long serialVersionUID = 1L;
private Long id;
...
@GeneratedValue
@Id
public Long getId() {
return id;
}

public void setId(Long id) {
this.id = id;
}
...
}

@Entity(name = "ClassB")
public class ClassB extends ClassA implements java.io.Serializable {
...
}

...ClassC extends ClassB ...

Notes that ClassB and ClassC have no id property.
gas3 generates such actionscript as following code(ClassABase.as,ClassBBase.as and ClassCBase.as are almost the same):
       ...
        public function set uid(value:String):void {
            // noop...
        }
        public function get uid():String {
            if (isNaN(_id))
                return "ClassA";
            return "ClassA:" + String(_id);
        }
        ...
The question is that:
1 uid should be overrided in ClassBBase.as
2 _id should be changed to id,because _id is private in super class.(in ClassBBase.as)
3 whether or not you add override befor uid in ClassCBase,it will be error. In som sense it should be added override.
  But in ClassBBase.as uid has already added it,and override can not be used again in inheritance hierarchy.
  
question 3 is new,question 1 and 2 have been post in http://www.graniteds.org/jira/browse/GDS-149,but i can't find valid entry to post a comment.
