You should always override the clone() method in a custom event class that adds 
new properties. Otherwise, re-dispatching such an event (calling 
dispatchEvent(event) inside a handler for that event) won't work properly.

You also may want to avveride the clone method in the custom event class:
/**
         *  @private
         */
        override public function clone():Event
        {
            return new RemoteClick(type, bubbles, cancelable);
        }
       - just omit the arguments if you are not using any

Cheers,
Claudiu

Hi,

Class names should begin with an Uppercase letter. RemoteClick not
remoteClick.
The type String can be lowercase if you want..

Something like the following..

package modulecode
{
import flash.events. Event;

public static const remoteClick: String="remoteCl ick";

public class RemoteClick extends Event
{
public function RemoteClick( type:String= "remoteClick" ,
bubbles:Boolean= false,

cancelable:Boolean= false)
{
super(type, bubbles, cancelable);
}
}
}

//Some component that dispatches and handles RemoteClick events
<MyCanvas>

<script>
public function handleButtonClick( ):void{
var eventObj:RemoteClic k = new RemoteClick( ); //no bubble
dispatchEvent( eventObj) ;
}

public function handleRemoteClickEv ent(e:RemoteClic k):void{
trace("handleRemote Click: "+e);
}

public function init():void{
addEventListener( "remoteClick" , handleRemoteClickEv ent);
}
</script>

<mx:FormItem label="" textAlign="right" >
<mx:Button label="Run" click="handleButton Click()" id="run"/>
</mx:FormItem>

</MyCanvas>

Or....

//Some component that dispatches RemoteClick events. NOTE : the name of
the event and the type.
<MyCanvas2>

<mx:Metadata>
[Event(name= "remoteClick" , type="modulecode. RemoteClick" )]
</mx:Metadata>

<script>
public function handleButtonClick( ):void{
var eventObj:RemoteClic k = new RemoteClick( ); //no bubble
dispatchEvent( eventObj) ;
}
</script>

<mx:FormItem label="" textAlign="right" >
<mx:Button label="Run" click="handleButton Click()" id="run"/>
</mx:FormItem>

</MyCanvas2>

Use MyCanvas2 in another component..

<ACanvas>
<script>
function handleRemoteClick( e:RemoteClick) :void{ ... }
</script>

<MyCanvas2 remoteClick= "handleRemoteCli ck(event) " ... />
</ACanvas>

HTH.
