Actionscript 3 在AdvancedDataGrid:TypeError:Error#1010中添加记录时：术语未定义且没有属性

TypeError:Error#1010:术语未定义且没有属性

我在flex中有一个可编辑的AdvancedDataGrid：

<mx:AdvancedDataGrid id="dgTrans" dataProvider="{arrDtlTransDP}" styleName="advancedDataGrid" left="5" right="50"
    doubleClickEnabled="true" itemDoubleClick="fn_EditFieldDetail(event);" maxWidth="850"
    editable="true" top="27" rowHeight="20" verticalAlign="middle" resizableColumns="true"  
    allowMultipleSelection="true" allowDragSelection="true"
    horizontalScrollPolicy="auto" height="460">
<mx:columns>
<mx:AdvancedDataGridColumn headerText="S No." dataField="rrd_Trans_No" labelFunction="fn_GetSNo" width="100" editable="false"/>
    <mx:AdvancedDataGridColumn headerText="Monthly Amount" dataField="rrd_Amount" width="110" labelFunction="fn_FormatAmountGrid"/>
    <mx:AdvancedDataGridColumn headerText="Effective From" dataField="rrd_Effective_From" width="100" rendererIsEditor="true"
        labelFunction="fn_FormateDate" itemRenderer="mx.controls.DateField" editorDataField="selectedDate"/>
    <mx:AdvancedDataGridColumn headerText="Narration" dataField="rrd_Narration" width="150" editable="true"/>
    <mx:AdvancedDataGridColumn headerText="Rental Income a/c" dataField="rrd_Acc_Code" id="rrd_Acc_Code" width="120" labelFunction="fn_FormatCOAGrid"/>
</mx:AdvancedDataGridColumn>
<mx:AdvancedDataGridColumn headerText="Description" dataField="rrd_Acc_Desc" id="rrd_Acc_Des" width="120" editable="false"/>

当我点击任何一列编辑这个虚拟数据时，我会遇到一个错误

TypeError:Error#1010:术语未定义且没有属性

首先，用数组填充arrDtlTransDP。立即将该项添加到arrDtlTransDP，跳过dgArray

像这样：

arrDtlTransDP = new ArrayCollection();
arrDtlTransDP.addItem({
    rrd_Trans_No:'1', rrd_Amount:'0.00', 
    rrd_Effective_From: new Date(2016,0,1), 
    rrd_Narration:'abc', rrd_Acc_Code:'0001', 
    rrd_Acc_Desc:'acd'});

其次，我们需要关于函数实现的更多信息，以便正确地告诉您可能存在的问题

我已经添加了这些实现，在我的上述更改中，它运行正常：

    protected function fn_FormatAmountGrid(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Amount;
    }

    protected function fn_FormatCOAGrid(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Acc_Code;
    }

    protected function fn_FormateDate(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Effective_From;
    }

    protected function fn_GetSNo(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Trans_No;
    }

    protected function fn_EditFieldDetail(event:ListEvent):void {
        // TODO Auto-generated method stub

    }

我希望这能有所帮助。

这是Advance Data Grid:trace（arrDtlTransDP）的结果是什么如果在代码顶部添加该变量，在访问其.additem（）方法之前，您是否在代码中的某个地方正确声明了“arrDtlTransDP”变量？像

var arrDtlTransDP:ArrayCollection=newarraycollection（）如果双击项目时出现错误，则可能还需要发布fn_EditFieldDetail（）方法
    protected function fn_FormatAmountGrid(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Amount;
    }

    protected function fn_FormatCOAGrid(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Acc_Code;
    }

    protected function fn_FormateDate(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Effective_From;
    }

    protected function fn_GetSNo(item:Object, column:AdvancedDataGridColumn):String {
        return item.rrd_Trans_No;
    }

    protected function fn_EditFieldDetail(event:ListEvent):void {
        // TODO Auto-generated method stub

    }
