[Simple-support] problem with generic list

[Paulo F. <pau...@gm...>]

hello,

i'm trying to use simple and so far it's been helpful. however, i'm
facing some difficulty with the problem sketched below:

  @Root
  class C {
    @Element
    String data;
    C(String data){
      this.data=data;
    }
  }

  class A<T> {
    @ElementList               // LINE (1)
    List<T> elements;        // LINE (2)
    A(){
      elements = new ArrayList<T>();      // LINE(3)
    }
    void add(T t) {
      elements.add(t);
    }
  }

  @Root
  class B {
    @Element
    A<C> aC;
    B() {
      aC = new A<C>();
    }
  }

  public void test() {
    B b = new B();
    b.aC.add(new C("hello"));
    b.aC.add(new C("world"));
    Serializer serializer = new Persister();
    File dest = new File("test.xml");
    try {
      serializer.write(b,dest);
    } catch (Exception e) {
      e.printStackTrace();
      fail();
    }
  }

with this code, it throws

org.simpleframework.xml.load.ElementException: Unable to determine
type for @org.simpleframework.xml.ElementList(inline=false, type=void,
required=true, data=false, name=, parent=)

i think i must add some type attribute to LINE (1), but don't know
exactly how to do it.

i also tryed to replace LINE(2) and LINE (3) by

List<Object> elements;        // LINE (2*)
elements = new ArrayList<Object>();      // LINE(3*)

but then it gives

org.simpleframework.xml.transform.TransformRequiredException:
Transform memex.common.test.MapSerialisationAdaptorTest$CTransform is
required for class memex.common.test.MapSerialisationAdaptorTest$C

i might be missing something very elementary and i'd really appreciate
if anyone could help me.

thanks in advance,

paulo
