如何在外部类中实现RemoteObject？

如何解决如何在外部类中实现RemoteObject？

| 这是代码：

public class Schem
{
    public var info:String=\"\";      

    public function Schem()
    {
    }

    public function loadCurrentSchem():void
    {
        var ro:RemoteObject = new RemoteObject(\"Hibernatetest\");
        ro.endpoint = \"http://Jesus/blazeds/messagebroker/amf\";
        ro.addEventListener(ResultEvent.RESULT,onResult);
        ro.getCells();
        info = info + \"Loader called ... \\n\";




    }

    public function onResult(event:ResultEvent):void
    {
        var array:ArrayCollection = event.result as ArrayCollection;
        info = info + \"Schemlength = \" + String(array.length)+ \"\\n\";
    }


    private function onFault(event:FaultEvent):void
    {
        info = info + \"Errorhandler Called\";
    }
    //Eventhandlers


    //Getters,Setters
}

不幸的是，当我调用loadCurrentSchem（）函数时，它没有到达eventHandler。怎么了？ 这就是我所说的课：

<fx:Script>
    <![CDATA[
        import argoseye.main.Golem;
        import argoseye.main.Schem;

        import mx.collections.ArrayCollection;
        import mx.rpc.AsyncToken;
        import mx.rpc.Responder;
        import mx.rpc.events.FaultEvent;
        import mx.rpc.events.ResultEvent;
        import mx.rpc.remoting.RemoteObject;

        protected function button1_clickHandler(event:MouseEvent):void
        {
            var schem:Schem = new Schem();
            schem.loadCurrentSchem();
            textfeld.text = schem.info;
        }

    ]]>
</fx:Script>

那里。     

解决方法

        问题是您没有正确确保结果处理程序正确调用。问题是，当您使用：

textfeld.text = schem.info;

您已设置以下值：

info = info + \"Loader called ... \\n\";

作为文本字段的文本，并且该值在结果处理程序中不会更改。 您可以通过至少两种方式解决此问题： 从

EventDispatcher

扩展

Schem

类，并将事件元数据放在此处。 班级：

[Event(name=\"result\",type=\"mx.rpc.events.ResultEvent\")]
[Event(name=\"fault\",type=\"mx.rpc.events.FaultEvent\")]
public class Schem extends EventDispatcher
{
    public var info:String=\"\";      

    public function Schem()
    {
    }

    public function loadCurrentSchem():void
    {
        var ro:RemoteObject = new RemoteObject(\"Hibernatetest\");
        ro.endpoint = \"http://Jesus/blazeds/messagebroker/amf\";
        ro.addEventListener(ResultEvent.RESULT,onResult);
        ro.addEventListener(FaultEvent.FAULT,onFault);
        ro.getCells();
        info += \"Loader called ... \\n\";




    }

    private function onResult(event:ResultEvent):void
    {
        var array:ArrayCollection = event.result as ArrayCollection;
        info += \"Schemlength = \" + String(array.length)+ \"\\n\";
        dispatchEvent(event);
    }


    private function onFault(event:FaultEvent):void
    {
        info += \"Errorhandler Called\";
        dispatchEvent(event);
    }
    //Eventhandlers


    //Getters,Setters
}

然后在您的MXML类中：

<fx:Script>
    <![CDATA[
        import argoseye.main.Golem;
        import argoseye.main.Schem;

        import mx.collections.ArrayCollection;
        import mx.rpc.AsyncToken;
        import mx.rpc.Responder;
        import mx.rpc.events.FaultEvent;
        import mx.rpc.events.ResultEvent;
        import mx.rpc.remoting.RemoteObject;

        protected function button1_clickHandler(event:MouseEvent):void
        {
            var schem:Schem = new Schem();
            schem.addEventListener(ResultEvent.RESULT,onResult);
            schem.addEventListener(FaultEvent.FAULT,onFault);
            schem.loadCurrentSchem();
            textfeld.text = schem.info;

        }

    private function onResult(event:ResultEvent):void
    {
        textfeld.text = event.currentTarget.info;
    }

    private function onFault(event:FaultEvent):void
    {
        textfeld.text = event.currentTarget.info;
    }
    ]]>
</fx:Script>

第二种方法是使用数据绑定。

Schem

班：

public class Schem
{
    [Bindable]
    public var info:String=\"\";      

    public function Schem()
    {
    }

    public function loadCurrentSchem():void
    {
        var ro:RemoteObject = new RemoteObject(\"Hibernatetest\");
        ro.endpoint = \"http://Jesus/blazeds/messagebroker/amf\";
        ro.addEventListener(ResultEvent.RESULT,onFault);
        ro.getCells();
        info += \"Loader called ... \\n\";
    }

    private function onResult(event:ResultEvent):void
    {
        var array:ArrayCollection = event.result as ArrayCollection;
        info += \"Schemlength = \" + String(array.length)+ \"\\n\";
    }


    private function onFault(event:FaultEvent):void
    {
        info += \"Errorhandler Called\";
    }
    //Eventhandlers


    //Getters,Setters
}

在MXML中：

<fx:Script>
    <![CDATA[
        import argoseye.main.Golem;
        import argoseye.main.Schem;

        import mx.collections.ArrayCollection;
        import mx.rpc.AsyncToken;
        import mx.rpc.Responder;
        import mx.rpc.events.FaultEvent;
        import mx.rpc.events.ResultEvent;
        import mx.rpc.remoting.RemoteObject;

        [Bindable]
        private var schem:Schem;

        protected function button1_clickHandler(event:MouseEvent):void
        {
            schem = new Schem();
            schem.loadCurrentSchem();
        }

    ]]>
</fx:Script>
<s:Label id=\"textfeld\" text=\"{schem.info}\" />

希望这可以帮助！ :)
