[Simple-support] obligation of "static public class" ?

[Patrice B. <pat...@sm...>]

Hello,
I see some persons mention a similar problem:  an exception occuring
when reading a list of elements.   And I read Niall answering "you must
declare a 'static public class' for the embedded items.   So I changed
my code to have both outer and inner classes in same file, with inner
class declared as static public class within the first class, like this:

@Root
public class PropertyList {

   @ElementList
   private List<Entry> list;

   @Attribute
   private String name;

   public String getName() {
      return name;
   }

   public List getProperties() {
      return list;
   }

@Root
public static class Entry {

   @Attribute
   private String key;

   @Element
   private String value;

   public String getName() {
      return name;
   }

   public String getValue() {
      return value;
   }
}

}


(I take this from the tutorial page, but with a minor change to embed
"Entry" into "PropertyList" and make it static.)

However, I still get the same exception when reading.   What is exactly
this obligation of a "public static class" and is it possible to find
the rules that apply.   The tutorial is VERY well done, for giving a
overview of the possibilities, but is it possible that the sample code
that are in the tutorial would not work ?

Sorry for this beginner's question.   I did go through the archive
trying to find the answer (although search function seems to be
unavailable).
