I solved it - the solution was in using an Array - not the ArrayCollection - when sending from Flex to web service.
So, it's convenient to have two types of collections - one for getting stuff from the web service, the other for putting stuff to the web service: [Bindable] public class MyDtoCollectionGet { public var IsError:Boolean = false; public var ErrorMessage:String = ""; public var Items:ArrayCollection; } [Bindable] public class MyDtoCollectionPut { public var IsError:Boolean = false; public var ErrorMessage:String = ""; public var Items:Array; } --- In flexcoders@yahoogroups.com, "Danko Kozar" <[EMAIL PROTECTED]> wrote: > > I've got a weird problem: > > - When passing an ArrayCollection (of strings) to the web service as > its method argument, everything works OK. > > - But, when wrapping an ArrayCollection (of objects) into a custom > collection object, only the first item in the collection is > transferred. > > The problem is in Flex - I checked this using Fiddler. > > --------------------- > > This is my DTO item: > > [Bindable] > public class MyDtoItem > { > public var Id:int = -1; > public var Name:String = ""; > public var Value:String = ""; > } > > I push my items into the MyDtoItem collection as its Items: > > [Bindable] > public class MyDtoCollection > { > public var IsError:Boolean = false; > public var ErrorMessage:String = ""; > public var Items:ArrayCollection; > } > > Then I send this collection to the web service method which should > accept it (I checked the WSDL). >
