[]List数据源的格式问题导致无法响应List的SelectHandler

1、List数据源设置的相关代码

var temp:Array = [];

var skillInfoVO:SkillInfoVO;

for(var i:int = 0;i<20;i++)

{

    skillInfoVO = new SkillInfoVO();

    skillInfoVO.Name = "数据源" + i;

    skillInfoVO.Lv = i;

    skillInfoVO.Color = 1;

    temp.push(skillInfoVO);

}

list.array = temp;

2、SkillInfoVO的相关代码

public class SkillInfoVO extends Data

{

    public var Lv:int;

    public var Name:String;

    public var Color:int;

}

3、Data的相关代码

public class Data extends EventDispatcher  

{

    public function Data()

	{

    }

	

    protected function dataSourceChange(eventType:String, property:String, value:Object):void

	{

        var data:* = this[property];

        this[property] = value;

        if (value != data)

		{

			var result:Boolean = event(eventType , {oldValue:data , newValue:value});

        }

    }

}

现在问题就出在Data这个类上面，如果将Data修改为继承Obejct，则List就可以响应SelectHandler，现在继承自EventDispatcher就不行。查看API发现EventDispatcher也的确继承自Object，麻烦帮忙测试下的。多谢
