Hello forum,

I'm new at Flex and ActionScript and I am in trouble with Web Service
Consumption. In my application, I need to call several times to the same Web
Service but with one different request parameter.

The thing is, that once performed all the .send(), the resultHandler is
called, but always with the last value I gave to that request parameter, so the
result is always the same.

I paste some of the code:

[..]
employeeID = "00005001";
wsGetEmployeeData.EmployeeGetdata.send();
employeeID = "00005002";
wsGetEmployeeData.EmployeeGetdata.send();
[..]
private function resultGetEmployeeData(event:ResultEvent):void{
xmlEmpData= wsGetEmployeeData.EmployeeGetdata.lastResult;
[..]
<mx:WebService id="wsGetEmployeeData" wsdl="url">
<mxperation name="EmployeeGetdata"
resultFormat="e4x"
result="resultGetEmployeeData(event);"
fault="faultGetEmployeeData(event);">
<mx:request>
<EmployeeId>{employeeID}</EmployeeId>
</mx:request>
</mxperation>
</mx:WebService>
[..]

Does anyone have an idea of how to call the Same Webservice?

Thank you,
toni

Hi Tonni, differents methods are possible in your case:

- call your ws with wsGetEmployeeData.EmployeeGetdata.send(employeeId)
- create a stack of ws calls (you're calling the next ws only when you
get result from the first one and then removing it from the stack of
ws).


Sample there:
//>>#######################################
private var isDoingAFlagRequest:Boolean = false;

private function onSetToFlag(event:EventData):void
{
stackFlagsToSet.addItem(event.data);
executeStackFlagsToSet();
}

private function executeStackFlagsToSet():void
{
if (!isDoingAFlagRequest)
{
if (stackFlagsToSet.length != 0)
{
isDoingAFlagRequest = true;
WsInduction.SetFlagToObject(stackFlagsToSet[0].InductionGuid,
stackFlagsToSet[0].FlaggedObjectGuid,
stackFlagsToSet[0].FlaggedObjectName,
stackFlagsToSet[0].FlagId,
onResultExecuteStackFlags);
}
}
}

private function onResultExecuteStackFlags(data:XMLList):void
{
isDoingAFlagRequest = false;
stackFlagsToSet.removeItemAt(0);
if (stackFlagsToSet.length > 0)
{
callLater(executeStackFlagsToSet);
}
}
//>>#######################################

Enjoy your Flex

It is my understanding that each WebService.send() will result in your
result handler being called. It is being called twice, but you are
probably only seeing the results of the second call as you are
overwriting the xmlEmpData variable.

I think that you can use AsyncTokens to track the different requests.

Hope this is some help

hi
why are you calling your webservices like that? there's an much easier way to
do that:
like this

if you have you webservice definition in mxm like

<mx:webservice name="youwebservice" wsdl="yourwebservice path?wsdl">
<mxperation name="youroperationname" result="your result handler function"/>
</mx:webservice>

then in actionscript you can call it like:

yourwebservice.youroperationname(yourparameter)

and this wil return each time a diferente result depending on what you send as
parameter.

the .send way is used with httpservice because it doesn't have methods defined
