Recursive structure - CORBA

Question

Hello
i am having some problems with a particular situation in CORBA. i am trying to invoke a server call and i am getting a BAD_PARAM exception (==? NULL references). Any kind of help would be greatly appreciated. Here is the sample codes:
IDL structure:
struct NestedStructure
    string name;
    sequence<NestedStructure> subField;
void getNestedStructure(out NestedStructureList data);
Server implementation :
public void getNestedStructure(NestedStructureListHolder data)
    System.out.println(data.value);
    data.value = myNestedStructure;
Client implementation :
public void getNestedStructure()
    NestedStructureListHolder dataHolder = new NestedStructureListHolder();
    myStub.getNestedStructure(dataHolder);
When i run them, i receive the following error message:
org.omg.CORBA.BAD_PARAM:   vmcid: 0x0  minor code: 0  completed: No

        at com.inprise.vbroker.orb.DelegateImpl.invoke(DelegateImpl.java:759)
        at org.omg.CORBA.portable.ObjectImpl._invoke(Unknown Source)
...when i add some value to the holder on the client before making the remote call, i still get the same exceptions. Moreover, the system output on the server side is also NULL in this case.
Any kind of help would be most appreciated. This has been annoying me for a while now.
Kind regards,
