DataGrid With RemoteObject

[Booma Devi]

Hi,

In the flex, Remote server is not displaying the datas to DataGrid... Below is the program...

DGridClient.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
	<![CDATA[
	        import mx.collections.ArrayCollection;
            import mx.controls.Alert;
            import mx.rpc.events.FaultEvent;
            import mx.rpc.events.ResultEvent;
      
          
            [Bindable]private var persons:ArrayCollection;

		
		private function faultHandler(event:FaultEvent):void
            {
                Alert.show(event.fault.faultDetail,"Error");
            }
         
         private function resultHandler(event:ResultEvent):void
		{
			persons=event.result as ArrayCollection;
	}


	]]>
</mx:Script>

<mx:RemoteObject id="serv" destination="remoteGrid" fault="faultHandler(event)"/>  
<mx:DataGrid dataProvider="{persons}" width="50%" height="50%" x="132" y="20">  
<mx:columns>
  <mx:DataGridColumn headerText="Name" dataField="name"/>  
  <mx:DataGridColumn headerText="Age" dataField="age"/>  
  </mx:columns>
  </mx:DataGrid> 
  <mx:Button id="btn" label="Get Person" click="serv.getList();" x="298" y="406">
  	
  </mx:Button>
</mx:Application>

package com.net.remote;

public class Person {

	public Person()

	public Person(String name, int age) {
		this.name = name;

}

Seems to me that you are missing a vital piece of information while you're creating the RemoteObject. Check again!

Thanks praveen... I need to map the java object with action script object...

Hi Booma Devi,

I dint mean that actually I was referring to line 28 in the first mxml where you have <mx:RemoteObject id="serv" destination="remoteGrid" fault="faultHandler(event)"/> defined. Here I dont see a result handler being declared, so I thought that would be the mistake.

As you have used the same strings('name', 'age') in datafields of mxml as well as attributes of class Person, I dont think there is a need to create an actionscript mapping class.

Thanks,
Praveen.

Thanks for your reply praveen...

My code is running now... :-)
