    Default Nullable Datetime field not getting rendered in Store (Ext JS)

    Nullable Datetime field not getting rendered in Store (Ext JS)


    <ext:Store ID="StoreSample" runat="server" RemotePaging="true" RemoteSort="true" AutoLoad="true"
    ShowWarningOnFailure="false" >
    <Proxy>
    <ext:HttpProxy Url="~/Samples/OpenEdit/GetSampleList" Json="true">
    </ext:HttpProxy>
    </Proxy>
    <Reader>
    <ext:JsonReader IDProperty="Id" Root="data">
    <Fields>
    <ext:RecordField Name="Id" Type="Int">
    </ext:RecordField>
    <ext:RecordField Name="SampleDescription" Mapping="Description">
    </ext:RecordField>
    <ext:RecordField Name="SamplestartDate" Mapping="StartDate" Type="Date">
    </ext:RecordField>
    <ext:RecordField Name="SampleEndDate" Mapping="EndDate" Type="Date" >
    </ext:RecordField>
    </Fields>
    </ext:JsonReader>
    </ext:Store>
    In this store the fields SampleStartDate and SampleEndDate are of type Nullabe Datetime (Datetime?) in the model. In controller i am getting value for every field and i am converting this to StoreResult in the function GetSampleList. But in store i am always getting the value as 'undefined' in these two fields. But if i change the datatype from Datetime? to DateTime the in model i am getting all the values in store.Can any one help me to get the nullable datetime value in store?

    Please try the following code and make any adjustments as needed to simulate your problem:

    Code:
    Ext.application({
        name: 'test',
        launch: function () {
            Ext.define('Company', {
                extend: 'Ext.data.Model',
                fields: [{
                    name: 'id',
                    type: 'int'
                }, {
                    name: 'todate',
                    type: 'date'
                }]
            });
    
            Ext.define('Companies', {
                model: 'Company',
                extend: 'Ext.data.Store'
            });
    
            var store = Ext.create('Companies');
    
            store.loadRawData([{
                "id": 1,
                "todate": "2011-08-08"
            }, {
                "id": 2,
                "todate": null
            }, {
                "id": 3,
                "todate": "2011-08-09"
            }]);
    
            var grid = Ext.create('Ext.grid.Panel', {
                store: store,
                columns: [{
                    header: 'Id',
                    dataIndex: 'id'
                }, {
                    header: 'To',
                    dataIndex: 'todate',
                    xtype: 'datecolumn'
                }],
                columnLines: true,
                width: 600,
                height: 300,
                title: 'GRID',
                renderTo: Ext.getBody()
            });
        }
    });​
    Regards,
    Scott.
