In Cairngorm a Command creates a Delegate which fires off (e.g.) a WebService operation. The way that's done in most Cairngorm examples is like this:
service = ServiceLocator.getInstance().getService('someWebService'); token = service.someWSMethod(someData); This AS way of triggering the WebService passes an outgoing argument (someData) to the mx:operation, which sends it to the remote web service. Problem is that in the Flex documentation, there are way more examples of using data binding inside an mx:operation to send those outgoing arguments... <mx:WebService id="employeeWS" destination="wsDest" showBusyCursor="true" fault=Alert.show(event.fault.faultstring)"> <mx:operation name="getList"> <mx:request> <deptId>{someDataProvider.data}</deptId> </mx:request> </mx:operation> </mx:WebService> In Cairngorm, to use the data binding method I'd have to bind to data in the ModelLocator, so even if the argument's data isn't something I'm tracking or storing in ModelLocator I'll have to store it in there for the WebService data binding to work. That sounds junky. That means when someone clicks on a selected person (or whatever) I'll have to first store them in ModelLocator, fire off the WebService operation, then in my result handler clean that temp selected person out of ModelLocator. But... If I use the AS method of firing off a WebService (which appears to be the proper way) and just do token = service.someWSMethod(someData) and pass in (someData) I don't have to worry about all that temp ModelLocator stuff... but... there's very little documentation on how to pass data into an mx:operation using AS. Actually I think there's only two, and they're very simplistic. I've gotten basic WebServices (with a single arg) to work the AS way, but what happens when I need to send multiple args to my remote web service? I know I can do token = service.someWSMethod(someData, otherData, evenMoreData) but how does the remote web service know which data maps to which args? Will the operation just process and send them in order, or are the variable names automatically changed into tags before calling the remote ws (e.g. someData is sent to the remote web service as <someData>someData's value</someData>)? Is there any documentation or examples out there that deal with this on a slightly more complex level? I just need to know how to call a WebService operation with multiple outgoing args, and to understand "the rules" behind passing args to WebService operations in AS. Anyone? Thanks!
