使用 [RemoteClass] 填充 ArrayCollection 属性
好的,我正在通过 WebOrb 将一个复杂对象从 .NET 库传递到我的 Flex 应用程序。 为了自动翻译,我使用 [RemoteClass] 元数据标记,如下所示:
[RemoteClass(alias="test.PlanVO")]
public class Plan
{
[SyncId]
public var id:int;
public var Name:String;
}
这绝对可以正常工作,直到我尝试扩展 Plan 类以包含复杂项目的数组:
.NET:
public class PlanVO
{
public int id { get; set; }
public string Name { get; set; }
public List<PlanElementVO> children { get; set; }
}
public class PlanElementVO
{
public string elementName { get; set; }
}
ActionScript:
[RemoteClass(alias="test.PlanVO")]
public class Plan
{
[SyncId]
public var id:int;
public var Name:String;
public var children:ArrayCollection;
}
[RemoteClass(alias="test.PlanElementVO")]
public class PlanElement
{
public var elementName:String;
}
在这种情况下,甚至当 .NET 库返回子级时,ActionScript Plan 类的 Children 属性为 null。
我尝试将 Children 字段更改为如下属性:
private var _children:ArrayCollection;
public function get children():ArrayCollection
{
return _children;
}
public function set children(o:*):void
{
if(o is ArrayCollection)
_children = o;
else if(o is Array)
_children = new ArrayCollection(o);
else
_children = null;
}
但 set 函数永远不会被调用。
我该怎么做才能让孩子们以这种方式进入我的 Flex 应用程序?
谢谢!
OK, I am passing a complex object from my .NET library to my Flex application via WebOrb.
In order to automatically translate, I am using the [RemoteClass] meta data tag as follows:
[RemoteClass(alias="test.PlanVO")]
public class Plan
{
[SyncId]
public var id:int;
public var Name:String;
}
This works absolutely fine, until I try to extend the Plan class to contain an array of complex items:
.NET:
public class PlanVO
{
public int id { get; set; }
public string Name { get; set; }
public List<PlanElementVO> children { get; set; }
}
public class PlanElementVO
{
public string elementName { get; set; }
}
ActionScript:
[RemoteClass(alias="test.PlanVO")]
public class Plan
{
[SyncId]
public var id:int;
public var Name:String;
public var children:ArrayCollection;
}
[RemoteClass(alias="test.PlanElementVO")]
public class PlanElement
{
public var elementName:String;
}
In this case, even when children are returned by the .NET library, the children property of the ActionScript Plan class is null.
I have tried changing the children field to a property like this:
private var _children:ArrayCollection;
public function get children():ArrayCollection
{
return _children;
}
public function set children(o:*):void
{
if(o is ArrayCollection)
_children = o;
else if(o is Array)
_children = new ArrayCollection(o);
else
_children = null;
}
but the set function never gets called.
What can I do to get the children into my Flex app in this way?
Thanks!

set 方法从未被调用,这对我来说并不奇怪。理论上,该对象应该从服务器返回,其中的项目已设置。
也就是说,我不认为 ArrayCollection 会与服务器端对象匹配。尝试在 Flex 中使用数组。在 .NEt 中,您应该使用“受支持”的类型之一。如果 List 是 IList 的实现,那么您可能没问题。

It's no surprise to me that the set method s never called. The object should, theoretically, return from the server with the items already set.
That said, I did not think that an ArrayCollection would match to a server side object. Try using an Array in Flex. In .NEt you should use one of the "supported" types. If List is an implementation of IList, then you're probably fine.
