    Default Problem updating a combobox selection list with an ArrayStore

    Problem updating a combobox selection list with an ArrayStore


    So I have a combo box that uses an ArrayStore for its data. The combo definition looks like this:
    Code:
    {
         xtype: 'combo',
        store: store1,
        mode: 'local',
        id: obj.rolesCombinedSelectComboId,
        hidden:!obj.set_btn_add,
        typeAhead: false,
        forceSelection: true,
        //triggerAction: 'all',
        lastQuery: '',
        emptyText: 'Please select',
        width: 85,
        minListWidth: 200,
        //tpl: tpl,
        displayField: 'display_name',
        valueField: 'event',
        fieldLabel: 'Add New',
        tooltip: 'Select an item to create',
        editable: false
    }
    And I have the following code to update the store when certain events happen:

    Code:
    if (!Ext.isEmpty(obj.rolesCombinedSelectComboId)){
         var cmb = Ext.getCmp(obj.rolesCombinedSelectComboId);
         if (!Ext.isEmpty(cmb)){
             cmb.store.removeAll();
             var newData = [];
             var arraydata = obj.setRolesCombinedSelectionArray(obj);
             for (var ad=0;ad<arraydata.length;ad++){
                 var newRec = new cmb.store.recordType({
                     id: arraydata[ad][0],
                     display_name: arraydata[ad][1],
                     event: arraydata[ad][2],
                     description: arraydata[ad][3],
                     icon: arraydata[ad][4],
                     xtype: arraydata[ad][5]
                 });
                 newData.push(newRec);
             }
             cmb.store.add(newData);
             cmb.store.clearFilter();
        }
    }
    I got the above code from the following thread:
    http://www.sencha.com/forum/showthre...th-ArrayReader

    I can see that the store gets updated with the new values, but the combobox dropdown does not display the new data. Can anyone tell me what I'm doing wrong here?

    Also, I should mention, I"m using Ext 3.4

    This is working for me in 3.4.0:

    Code:
    var store = new Ext.data.ArrayStore({
        fields : [
            'event', 'display_name'
        ],
    
        data : [
            [1, 'One'],
            [2, 'Two'],
            [3, 'Three'],
            [4, 'Four'],
            [5, 'Five']
        ]
    });
    
    var form = new Ext.form.FormPanel({
        renderTo : Ext.getBody(),
        width    : 400,
        height   : 400,
        title    : 'Test',
        items    : [
            {
                xtype: 'combo',
                store: store,
                mode: 'local',
                typeAhead: false,
                forceSelection: true,
                //triggerAction: 'all',
                lastQuery: '',
                emptyText: 'Please select',
                width: 85,
                minListWidth: 200,
                //tpl: tpl,
                displayField: 'display_name',
                valueField: 'event',
                fieldLabel: 'Add New',
                tooltip: 'Select an item to create',
                editable: false
            }
        ]
    });
    
    setTimeout(function() {
        console.log('add data');
    
        var recs    = [],
            recType = store.recordType;
    
        recs.push(new recType({
            event        : 7,
            display_name : 'Seven'
        }));
    
        recs.push(new recType({
            event        : 8,
            display_name : 'Eight'
        }));
    
        store.add(recs);
    }, 2000);
