WebMapUtil error thrown when there is no internet connectivity

SilviaPetcu — Mon, 19 Mar 2012 12:11:02 GMT

If there is no internet connectivity and try to load a Web Map the next error is thrown:

TypeError: Error #1034: Type Coercion failed: cannot convert mx.rpc.events::FaultEvent@13a5a301 to com.esri.ags.events.LayerEvent.

My WebMapUtil object has a listener to a FaultEvent but the event is never triggered.
I'm using agslib-2.5-2011-11-30.swc library.

Silvia, no.

If I disable my network device i recieve this error message:

[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error.

You need to search in adobe forums about: "event listeners", "event dispatchers".

cannot convert mx.rpc.events::FaultEvent@13a5a301 to com.esri.ags.events.LayerEvent

just fill the difference:

wrong code:

var wmUtil:WebMapUtil = new WebMapUtil();
wmUtil.addEventListener(FaultEvent.FAULT, onWebMapUtilFault, false, 0, true);

protected function onWebMapUtilFault(event:LayerEvent):void // wrong event type
{
    //
}

/*
TypeError: Error #1034: Type Coercion failed: cannot convert mx.rpc.events::FaultEvent@ad35f81 to com.esri.ags.events.LayerEvent.
...
...
*/

working code:

var wmUtil:WebMapUtil = new WebMapUtil();
wmUtil.addEventListener(FaultEvent.FAULT, onWebMapUtilFault, false, 0, true);

protected function onWebMapUtilFault(event:FaultEvent):void
{
    trace(event.fault.getStackTrace());
}
