Hi Nick,
I would use an other data structure.
class Item {
int nodeId;
int parentId;
String name;
// .. more Data
}
class TreeData extends ArrayList<Item> implements IsSerialisable {}
or
class TreeData implements IsSerialisable {
public ArrayList<Item> items;
}
And you should asure that a parent appear before its children.
If you like you may remove nodeId and substitue it by the index.
