PropertyGrid中的组合框

Question

我有一些商店，它是数据。在面板上，它看起来如何“ fieldName”和文本字段（与调用的形式有所不同）。

例如，在一种形式上显示“名称文件”和字段，在另一种形式上显示：销售日期和日期字段。数据是动态形成的。

这是商店：

tableTempStore = new Ext.data.JsonStore({
        url: objectUrlAddress,
        baseParams: {
            'objectID' : objectID
        },
        root: 'Fields',
        fields: [
            {name: 'Hint'},
            {name:'Type', type: 'int'},
            {name: 'Value'},
            {name: 'Index', type: 'int'},
            {name: 'IsRequired', type:'bool'},
            {name: 'Identifier'},
            {name: 'EnumList'},
            {name: 'Directory'},
            {name: 'Data'}
        ],
        listeners: {
            load: function(obj, records) {
                Ext.each(records, function(rec) {
                    var item = null;
                    switch (rec.get('Type')) {
                    case 0: // целое
                            item = new Ext.form.NumberField();
                            item.id = rec.get('Identifier');
                            item.fieldLabel = rec.get('Hint');
                            var isRequired = rec.get('IsRequired');
                            item.anchor = '100%';
                            item.allowBlank = ! isRequired;
                            item.disabled = editDisabled;
                            item.value = rec.get('Data');
                            break;
                        case 1: // вещественное
                            item = new Ext.form.NumberField();
                            item.id = rec.get('Identifier');
                            item.fieldLabel = rec.get('Hint');
                            var isRequired = rec.get('IsRequired');
                            item.anchor = '100%';

                        }
                            source[item.fieldLabel] = '';
                            grid.customEditors[item.fieldLabel] = s;
                            grid.setSource(source);
                       };
                });
            }
        }
    });

这是属性网格

grid = new Ext.grid.PropertyGrid({
        title: 'Заполнение шаблона',
        url: objectUrlAddress,
        id: 'propGrid',
        autoFill: true,
        autoHeight: true,
        width: 200,
        store: tableTempStore,
        width: 600,
        style: 'margin:0 auto;margin-top:10px;'
        });

组合框问题。他在单元格上显示itemValue而不是fieldValue，我不知道如何解决此问题。我能怎么做？感谢您的进步。
