DHTMLXTree: locked tree?

When executing a full expand of the tree (opens all items dynamically), I get an exception "'that.G_node.id' is null or not an object" whenever I expand some other node in the meantime... I guess this behaviour is normal when messing with the tree's internal state variables (the queue of nodes used while opening the nodes dynamically), but how can I avoid it?

PS. I implemented the onAllOpenDynamic myself, by doing the following in dhtmlxtree_xw:

dhtmlXTreeObject.prototype.openAllItemsDynamic = function(itemId)
{
    //alert("can see you");
    this.ClosedElem=new Array();
this.G_node=null;
var itemNode = this._globalIdStorageFind(itemId||this.rootId);
this.onLoadReserve = this.onXLE;
this.onXLE=this._loadAndOpen;
if(this._getOpenState(itemNode)<0)this._HideShow(itemNode,2);
if(itemNode.XMLload==0)this.ClosedElem.push(itemNode);
//this.setOnLoadingEnd(this._loadAndOpen);
this._openAllNodeChilds(itemNode,0);
if(this.ClosedElem.length>0)this._loadAndOpen(this);
};


Thanks
