paging toolbar not displaying properly

[dorgan]

All of a sudden I the area where the paging toolbar should be is now blank. Why would this happen

MyDesktop.OrderLookResultsGrid = Ext.extend(Ext.app.Module, {
    init : function( results ){
        this.launcher = {
            text: 'Order Lookup Results',
            iconCls:'icon-find',
            handler : this.createWindow,
            scope: this
        };
        
    },
    setData: function( sop, po ) {
        this.sopnumbe = sop;
        this.cstponbr = po;
        //this.data = Ext.util.JSON.decode( data );
        OrderLookupDS = 
            new Ext.data.Store({
                url: 'findorder.php?sopnumbe=' + this.sopnumbe + '&cstponbr=' + this.cstponbr,
                //method: 'POST',
                remoteSort: true,
                fields: [
