Children are automatically removed when you remove the parent component from it’s parent. Could you clarify what you mean?

You need to remove the child elements first, e.g. recursively. So, before you delete the parent, dom something like

for(Object child: new HashSet<Object>(tree.getChildren(parent)){
   tree.removeItem(child);
}

If you have many levels of children, just make that a recursive method instead.
