Yes. I'm using POJO and annotating one of the field with RiakIndex. When
I'm reading the object with the key, as the tag field is not part of the
object, while writing I dont have the tag value while writing the object.
Class Foo {
private String fooId;
@RiakIndex(name="barid")
private String barid;
.....
}
When I'm storing the object, I set the barid for the object and storing the
object. Annotation is taking care of tagging the object with barid.
When I query the object with barId, I have the barId value so I'm setting
barId to object and writing it. But If I lookup the object with fooId, as
barId value is not part of the object I cant tag the object with barid. SO
when I'm writing the object I'm losing the association .
So Is there any thing I'm missing to make it part of the object state. That
way as you said, When I read-modify-write, the tag value exist all the time.
Thanks
Santi
