Dojo: dojox.grid.enhanced.plugins.Filter - all items are cleared from the grid on filtering

I've got a dojox.grid.EnhancedGrid with a dojox.grid.enhanced.plugins.Filter and a dojo.store.Memory wrapped in a dojo.data.ObjectStore. Whenever I try to filter, all records are removed from the grid. I get a '0 of 0 items shown' message. When i click 'clear filter' the grid remains empty.

Update: The plot thickens. It seems that just sorting the grid by a column clears the grid. I'm trying to get a basic example working here: http://jsfiddle.net/wp64T/4/

Solution

I had the same problem and only managed to fix it by running the grid filter periodically in the background with the help of some jQuery. Here is some sample code; hope this helps someone else having problems with this.

// ADD JQUERY
<script src="http://code.jquery.com/jquery-latest.js"></script>

// PUT THIS IN THE <HEAD> OF THE PAGE
<script type="text/javascript">
    $(document).ready(function() {
        function filterTheDataGrid() {
            if (dijit.byId("grid") != undefined) {
                dijit.byId("grid").filter({color: "Red"});
            }
        }
    // RUN THE filterTheDataGrid FUNCTION EVERY ONE SECOND (1000 MILLISECONDS) //
    // LOWER '1000' FOR FASTER REFRESHING, MAYBE TO 500 FOR EVERY 0.5 SECOND REFRESHES //
    var refreshDataGrid = setInterval(function() {  filterTheDataGrid();    }, 1000);
    }
</script>

// PUT THIS IN THE <HEAD> OF THE PAGE
<script type="text/javascript">
    // SETUP THE LAYOUT FOR THE DATA //
    var layoutItems = [[
    {
        field: "id",
        name: "ID",
        width: '5px',
        hidden: true
    },
    {
        field: "color",
        name: "Color",
        width: '80px'
    }
]];

// Create an empty datastore //
var storeData = {
    identifier: 'id',
    label: 'id',
    items: []
}
var store3 = new dojo.data.ItemFileWriteStore( {data : storeData} );
</script>

 // PUT THIS IN THE <HTML> OF THE PAGE
<div id="grid" dojoType="dojox.grid.DataGrid" jsId="grid5" store="store3" structure="layoutItems" query="{ type: '*' }" clientSort="true" rowsPerPage="40"></div>

<script type="text/javascript">
function addItemToGrid(formdata) {
    // THIS FUNCTION IS CALLED BY A DIALOG BOX AND GETS FORM DATA PASSED TO IT //
    var jsonobj = eval("(" + dojo.toJson(formData, true) + ")");

    var myNewItem = {
        id: transactionItemID,
        color: jsonobj.color
    };
    // Insert the new item into the store:
    store3.newItem(myNewItem);
    store3.save({onComplete: savecomplete, onError: saveerror});
}
</script>
