Hey there,
I want to make a RPC Call with an Object called Feature. This class
included an ArrayList with refereces to other Object. So when I do the
RPC Call and want to reach the Object from the ArrayList, i get the
following Eception:

Is it because of the ArrayList? Thats my Class:
public class Feature implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
private ArrayList<Group> subgroups = new ArrayList<Group>();
private String context;
public Feature(){
}
public Feature(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public void addSubgroup(Group group) {
subgroups.add(group);
}
public ArrayList<Group> getSubGroups() {
return subgroups;
}
}
And that is my Call:
public void test() {
AsyncCallback<String> callback = new AsyncCallback<String>() {
public void onFailure(Throwable caught) {
caught.printStackTrace();
}
public void onSuccess(String result) {
Window.alert(result);
}
};
Feature feature2 = new Feature("test Feature");
Feature feature = new Feature("root");
Group group = new Group(GroupType.mandatory,feature2);
feature.addSubgroup(group);
SpeicherService.Util.getInstance().test(feature, callback);
}
