Seeking for help to resolve this scenario.
The problem here is that capitalization of `aDocId` is problematic and does not really match implicit name that getter/setter would produce. Because of this, Jackson things there are 2 different properties (with different casing). This only affects the specific case of single-lower-case-letter. There are 2 ways to resolve this: 1. Move `@JsonProperty` annotation to getter or setter -- there is no need to annotate Field, usually, and since it is private, it should be ignore if not annotated 2. Add duplicate of `@JsonProperty` on getter or setter -- this will link Field and getter/setter Methods to make them be part of one single logical propery I hope this helps, -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
