| ERROR | unqualified instance attribute references allowed only in member methods |
| CAUSE | An attempt was made to use the name of an object instance attribute in the body of a static method, or in an initialization default value on another attribute. If the instance attribute is not qualified with a particular object instance that supplies a value, the instance attribute can be named only when it is inside a member method. |
| ACTION | Qualify the attribute reference with the name of an object value, or change the containing method to a member method rather than a static method. |
