Hello,
I want to access a webservice:getMonitorData() , on creationcomplete and returns an array, in an infinite
loop so that the getIndex0.text is updated each time.
Flex is not able to handle an infinite
loop and gives a timeout error 1502. If I run the for
loop until i<2000 or so it works fine.
How can replace the
loop so that my webservice is accessed continiously and the result is shown in getIndex0.text.
This is how my application looks like:
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"
xmlns:plcservicebean="server.services.plcservicebean.*"
creationComplete="clientMonitor1()">
<fx:Script>
<![CDATA[

//-----------Infinite

public function clientMonitor1():void{
for(var i:int = 0; ; i++){
clientMonitor();
}
}
public function clientMonitor():void{
var callResp:CallResponder = new CallResponder();
callResp.addEventListener(ResultEvent.RESULT, monitorResult);
callResp.addEventListener(FaultEvent.FAULT, monitorFault);
callResp.token = plcServiceBean.getMonitorData();
}
public function monitorResult(event:ResultEvent):void{
var arr:ArrayCollection = event.result as ArrayCollection;
dbl0 = arr[0].value as Number;
}
protected function monitorFault(event:FaultEvent):void{
Alert.show(event.fault.faultString, "Error while monitoring Data ");
}
]]>
