                               {
                                            xtype:'combo',
                    name : 'policyId',
                    fieldLabel : 'policyTyep',
                    padding : 'padding-left: 20%',
                    displayField : 'analysisName',
                    valueField : 'analysisId',
                    queryMode : 'local',
                    //value:-1,
                    value: {analysisName:'Select..',
                            analysisId:0},
                    store : policyDetailTypeStore
                }
                       If I the policyDetailTypeStore is loaded ,but have no data.

然后我想在combox中显示"Select ...".我也将值配置为代码,但根本无法工作..
