User-Defined Data Type (Data Transfer Objects) is null

Question

hi
i try to access a nested complex datatype over blazeds. i always see that the second level of the  complex datatye is NULL but the other data's like String are ok.
here an example:
as you can see TT1 has a member TT2, and a String
TT2 has a member TT3 and a string
and TT3 has just a string.
in the ActionScript the TT2 referenz in TT1 is always NULL.
Java Code
Java code:
package clientreportingserver;
public class TT1 {
    public String getT1s() {
        return t1s;
    public void setT1s(String t1s) {
        this.t1s = t1s;
    String t1s;
    public TT2 getTt2() {
         return tt2;
    public void setTt2(TT2 tt2) {
         this.tt2 = tt2;
    TT2 tt2;
=================================================
package clientreportingserver;
public class TT2 {
    public String getT2s() {
        return t2s;
    public void setT2s(String t2s) {
        this.t2s = t2s;
    String t2s;
    public TT3 getTt3() {
         return tt3;
    public void setTt3(TT3 tt3) {
         this.tt3 = tt3;
    TT3 tt3;
=================================================
package clientreportingserver;
public class TT3 {
     public String getT3s() {
        return t3s;
    public void setT3s(String t3s) {
        this.t3s = t3s;
    String  t3s;
ActionScript DataType
package clientreporting.model
import mx.collections.ArrayCollection;
[RemoteClass(alias="clientreportingserver.TT1")]
[Bindable]
public class TT1
    public var t1s:String;
    public var t2:TT2
====================================================================
package clientreporting.model
import mx.collections.ArrayCollection;
[RemoteClass(alias="clientreportingserver.TT2")]
[Bindable]
public class TT2
    public var t2s:String;
    public var t2:TT3
===================================================================
package clientreporting.model
import mx.collections.ArrayCollection;
[RemoteClass(alias="clientreportingapi.TT3")]
[Bindable]
public class TT3
    public var t3s:String;
here the output from blazeds. for me it looks perfect, all data are transmitted

(Byte Array #6, Length 16)
the last Alert (accessing t2) got always a null pointer, the fist Alert works fine and print out the string i expected to see
call in ActionScript
    public function loadTT():void {
       _policyService.getTT(loadTTHandle);
    private function loadTTHandle(content:TT1):void {
       Alert.show("" + content.t1s);
       Alert.show("" + content.t2.t2s);
is it possible to access a nested complex type? i only could find simple examples.
thanks for your help joe

I found the problem
in the flashlog.txt i found :ReferenceError: Error #1056: Cannot create property AFoo on [...]
