Cédric Chantepie commented on EJB-338:
--------------------------------------

I''ve asked on IRC. 

I may be wrong but according JPA specs @Column annotation could be added on field or on getter in equivalent way, so why should it be different for query ?

> When binding property with @Column annotation arround corresponding getter query "cannot resolve property", whereas all other persistence features (EntityManager.{persist,find,...}) properly supports it. 
> Just moving annotation to the private field fix this issue, but in some case you really want to mapped property from its getter and not from private (protected) field.
> Annotation binding (causing issue) :
> [...] class ProcessStateEntity {
> [...]
>   @Column(name="col")
>   public Calendar getOccured() { ... }
> [...]
> }
> Query exception :
> org.hibernate.QueryException: could not resolve property: occured of: xxx.ProcessStateEntity [SELECT s.occured FROM xxx.Pr
> ocessStateEntity s]
