[CS-FSLUG] OT: Any Dojo Toolkit Users on Here?

[Timothy Butler]

I'm stuck with a Dojo problem. I'm trying to create a lazy loading tree. To do so, I am trying to use dojox.data.QueryReadStore as the store for the lazy loading dijit.tree. I seem hard pressed to find examples of people using this store instead of dojox.data.JsonRestStore, but I would really like to stick to using query strings as opposed to REST syntax for the sake of consistency throughout my application. The trouble is, while I can get QueryReadStore to pass along the root level of the tree, lazy loading the children, it always fails. 

Here's what I have:

	    dojo.require("dojox.data.QueryReadStore");
            dojo.require("dijit.Tree");



            dojo.addOnLoad(function() {
                var store = new dojox.data.QueryReadStore({
                	url:'/cgi-bin/safari/safari_json_responder.pl',
				    requestMethod: "get"
                });

                var treeModel = new dijit.tree.ForestStoreModel({
					store: store,
					deferItemLoadingUntilExpand: true,
					query: { 'id' : "0" },
					childrenAttrs: ["children"]
                });

                var myTree = new dijit.Tree({
                    model: treeModel
                },
                "treeOne");
                
                myTree.startup();
                
            });

When I click to expand one of the categories that has children, I get this error from Firebug:

> Node cannot be inserted at the specified point in the hierarchy" code: "3 
> [Break On This Error] (function(){var _1=null;if((_1||(typeo...setTimeout(dojo._loadInit,100);}})(); 

Any suggestions on what might be the issue? You can see the live test page here:

Thoughts?
