dhtmlxTree -- setAutoLoading (Dynamical Loading in dhtmlxTree v.1.x)

Hi,

I need your help with setAutoLoading feature in dhtmlxTree.

Parent.xml:

<?xml version="1.0" encoding="iso-8859-1" ?>
<tree id="0">
<item text="Surveillance" id="a1" im0="dhtmlxtree_icon.gif" im1="dhtmlxtree_icon.gif" im2="dhtmlxtree_icon.gif" child="1" />
<item text="Apple" id="app" im0="dhtmlxtree_icon.gif" im1="dhtmlxtree_icon.gif" im2="dhtmlxtree_icon.gif" child="1" />
</tree>

Child.xml:

<?xml version="1.0" encoding="iso-8859-1" ?>
<tree id="a1">
    <item text="Hello" id="a3" im0="dhtmlxtree_icon.gif" im1="dhtmlxtree_icon.gif" im2="dhtmlxtree_icon.gif" child="0"/>
<item text="Hel" id="ga3" im0="dhtmlxtree_icon.gif" im1="dhtmlxtree_icon.gif" im2="dhtmlxtree_icon.gif" child="0"/>
</tree>

<tree id="app">
    <item text="Aapple11" id="Aapple11" im0="dhtmlxtree_icon.gif" im1="dhtmlxtree_icon.gif" im2="dhtmlxtree_icon.gif" child="0"/>
<item text="Aapple111" id="Aapple111" im0="dhtmlxtree_icon.gif" im1="dhtmlxtree_icon.gif" im2="dhtmlxtree_icon.gif" child="0"/>
</tree>

JS:
function callTree(){
var tree;
    tree=new dhtmlXTreeObject(document.getElementById('treeBox'),"400%","150%",0);;
    tree.setImagePath("codebase/imgs/");
    tree.enableCheckBoxes(false);
    tree.setXMLAutoLoading("http://localhost/xml/Child.xml");
    tree.loadXML("http://localhost/xml/Parent.xml");//load root level from xml
}


Issue:

While browsing the top node, it give an loadxml error. According to "Dynamical Loading in dhtmlxTree v.1.x" documentation, this should work as for each parent "id" you have a corresponding child "id" in the <tree> </tree> format.

Kindly help.

Thanks,
Mohit.
