[Users] How to get unrendered child nodes

[geographika]

Hi,

Depending on the node type the children exist if the node hasn't been 
expanded. I added a listener for a gx_overlaylayercontainer to expand 
and switch all child nodes on if the parent is switched on:

{
                     "nodeType": "gx_overlaylayercontainer",
                     "expanded": false,
                     checked: false,
                     "text": "Parent Node",
                     listeners: {
                         "checkchange": function(node, checked){

                             if(checked){
                                 //need to load all the child nodes to 
switch them on
                                 node.expand();
                             }
                             node.eachChild(function(n){
                                 n.getUI().toggleCheck(checked);
                             });
                         }
                     },
