求教高手,NumericStepper 作为itemrenderer 内存上溢
代码如下,麻烦高手给试运行一下:

                        public var dgArray:ArrayCollection = new ArrayCollection([
                                {foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:10},

                                <mx:itemRenderer>
                                        <fx:Component>
                                                <mx:NumericStepper value="{data.daizuo}"  minimum="1" maximum="{data.daizuo}" stepSize="1" >
                                                </mx:NumericStepper>
                                        </fx:Component>
                                </mx:itemRenderer>

                </mx:columns>
        </mx:AdvancedDataGrid>
</s:Application>

我的需求是,从数据源中取出daizuo 属性,作为最大值和当前值. 可是有问题,麻烦大哥们帮忙一下,先谢过了,小弟学flex不久,折腾一晚上了
[解决办法]
这个很简单，自己多实践下就可以了。

</fx:Declarations>

<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
public var dgArray:ArrayCollection = new ArrayCollection([
{foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:10},
{foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:2},
{foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:4},
{foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:4},
{foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:4},
{foodName:"AA",tableNum:"男性",deliveredNum:"30",daizuo:4}
]);
