我正在开发一个函数，可以根据对DB的调用在Flex中在运行时生成表单。对DB的调用返回字段类型，id，工具提示等作为arraycollection，然后解析arraycollection以确定基于数组中的类型字段显示什么控件 - 这个位工作正常。
但是，我仍然试图使用CFC将表单字段保存回数据库。
我的表单呈现代码如下，但如何保存输入数据库的值？
我的渲染代码..

以与Flex接收数据相同的方式将数据发送回CF.
创建通用Object的实例，向其添加属性;我猜id，default_text，label，direction，required，tooltip等...添加'finalVAlue'属性。
在CF中，我认为默认对象应该显示为结构;虽然如果可能的话，我强烈建议在cF和Flex中为这些数据创建一个Value Object，并使用Flex Remoting CFC到AS3对象映射。
如果您需要访问您创建的Flex中的所有表单元素，而不知道ID，则可以使用numChildren和getChildAt对所有子项执行循环。
更新： 以下是创建通用对象和添加属性的示例：
var newObject : Object = new Object();
newObject.property1 = 'some value';
newObject.property2 = 'some other value;
newObject.finalValue = textInput.text;
