I have a items in a data store that have a position object. For an array of items in the store, here's a sampling of the position attributes that the items might have:

position : 1
position : 1.1
position : 1.15
position : 1.15.1
position : 1.2.7
position : 2
position : 2.1

While it's easy enough to issue a query to the store for all position 1 items, such as query:{position:'1'}
- returns example 1 above

and it's pretty easy to issue a query for all level 1 items, such as query:{position:'?'}
- returns example 1 and 6 above

I am new to dojo, just got a big headache :-( when working on client-side pagination. But I really love Dojo, and want to use it :-) .
The demo somewhere in forum is just not working in Dojo1.1. http://osdir.com/ml/web.dojo.devel/2006-10/msg00013.html

** Error found:
With coding and Json below, I can only go to next item, but then got a problem which actually already reported here in forum ( dojo datastore automatically combined (messed up?) with previous store fetched).
In console, it just showed combined page1 and page 2, but I can never navigate to page 3. Why ??

I'm trying to figure out how to plug in a JSON-RPC service with a grid.

There doesn't seem to be a dojo.data store for json-rpc, however all the plumbing is there for doing the rpc calls. Anyone have suggestions on how to go about this?

My service controller (Zend Framework) looks something like this:

public function jsonAction ()
{
$server = new Zend_Json_Server();
$server->setClass("MyClass_RPC_" . $this->_getParam('class'));
$server->setAutoEmitResponse(true);
if ('GET' == $_SERVER['REQUEST_METHOD']) {

For the last couple of days, I've been trying to find the way to use the XML backend of the dijit.Tree widget, as the documentation says it should be possible. Quoting http://dojotoolkit.org/node/3157:

The easiest data-driven way to approach this uses dojo.data. Dojo.data reminds Andy of ODBC in the Windows world, JDBC in Java, and DBD in PHP (Andy gets around.) Though dojo.data can talk to many different kinds of backing stores formatted in CSV, XML or HTML, Andy picks JavaScript Object Notation, or JSON.

I am playing around with Dojo, and I wanted to be able to store start/end times in some sort of data store. However, storing the items has caused me some trouble. Below I have given relevant code..

  var store = new dojo.data.ItemFileWriteStore({url: '/data/store.json'});
  
  // Passing in a random/unique id
  function startTime(id) {
    timers[id] = new Date();
			
    var storeTime = store.newItem({timerId: '1234', type: 'start', time: timers[id] });
    store.save({onComplete: saveDone, onError: saveFailed});

    var gotName = function(items, request) {
