The error message uses the term state field, because the JPA uses the term state field for a persistent field or property. This depends on whether the entity class uses field based or property based access type. Where do you place your annotations such as @Id or @Basic: on the field or on the getter? Please note, a single access type applies to an hierarchy of entity classes, defined by the root entity class (sample.entity.Value in your case).
The query compiler tries to find a persistent field called asString or a persistent property asString meaning a getter method getAsString in class Value depending on whether Value has a field or property based access type. In your sample code the getter getAsString was annotated as @Transient, so it is not persistent property and cannot be used in a query.
I hope this helps.
Regards Michael
