组件里面更新数组对象失败

[zhongzepeng]

组件里面data设置了一个数组对象，发现调用setData方法无法更新，应该是这里的问题
// Recurse if we're merging plain objects or arrays
if (deep && copy && (is.hash(copy) || (copyIsArray = is.array(copy)))) {
if (copyIsArray) {
copyIsArray = false;
clone = src && is.array(src) ? copy : [];
} else {
clone = src && is.hash(src) ? src : {};
}

      // Never move original objects, clone them
      target[name] = extend(deep, clone, copy);

    // Don't bring in undefined values
    } else if (typeof copy !== 'undefined') {
      target[name] = copy;
    }
