org.apache.myfaces.trinidad.change.RowKeySetAttributeChange
Handles RowKeySetAttribute changes, which need to be handled specially because they are mutable and programmers assume that the instances don't change. Cases that we need to worry about: 1) old value is null 2) new value is null (should clear existing RowKeySet if possible) 3) old value = new value 4) new value is a ValueExpression or ValueBinding 5) old value is a ValueExpression that needs to be evaluated in context 6) RowKeySet is internally bound to a model that needs to be evaluated in context

    
    FacesContext context = getFacesContext();

                                        attributeValue);
