Hi,

I have a case where I'm invoking saveOrUpdate(), where I expect the object to be updated. Instead, it's getting saved (I have hibernate.show_sql:true, and I'm seeing SQL inserts instead of updates). I set the log level to debug, but unfortunately the first message it prints is

Code:
DEBUG - saving [com.my.class.Name#<null>]


Not sure why it thinks it's "#null"! I put in some scaffolding to print the identifier property of the object, and it's not null

answer is most likely: fix your getId() method.

Hmmm, thanks...

here's what my id property looks like:

Code:
   /**
    * @hibernate.id
    *   generator-class="native"
    *   column="id"
    */
   public Long getId() {
      return _id;
   }
   public void setId(Long id) {
      _id = id;
   }


I'm having trouble imagining what it should be other than this...? Any other possibilities? Does the scenario I outlined conform to "best practice" for using Hibernate in a Web application?

thanks,
mark

Please make sure you are not accidentially overwriting the id with null in your steps 4/5.

How about check your unsaved-value?
