错误描述
???????????????? flex在加载module时报出如题所示的错误,
实际表现
问题就出现在这 我取消这个错误提示框 再次在前台查询数据 就一切ok
问题就出现在这一句
var zoufangModel:ZfRecord=ZfRecord(data);
调试
第一次是这样 继续就出抛出错误
取消错误再次查询 调试的结果就是这样
多了个[inherited] 确实第二次是正常的 但为什么第一次不行 到现在也不明白
解决方法
将错误的那一句改成
var zoufangModel:ZfRecord = ObjectTranslator.objectToInstance( data,ZfRecord ) as ZfRecord;
ObjectTranslator类的代码如下
