I have a dynamic Class that is a Value Object that is used to pass arguments to a WebService. It has two public properties:

package {     [Bindable]     public dynamic class WebServiceCriteria     {         public var property1:String;          public var property2:String;     } }

I set these two properties in one part of my application:

var myCriteria:WebServiceCriteria = new WebServiceCriteria();  myCriteria.property1 = 'x';  myCriteria.property2 = 'y';

Then I added other – dynamic – properties at another point in my application:

myCriteria.property3 = 'z';

However, when I pass the instance to the WebService as the arguments, the original two public properties are not sent (as I can see in Fiddler), even though they have values. But, I can see them as properties of my Class instance in the debugger just prior to the send().

operation.arguments = {args: myCriteria};  operation.send(); // only property3 is sent

Why are those two properties not sent?

Here is an example of the SOAP request sent to the WebService:

<SOAP-ENV:Envelope xmlns:SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>   <SOAP-ENV:Body SOAP-ENV:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/'>     <intf:webservice_controller xmlns:intf='http://childDir.parentDir'>       <args xsi:type='apachesoap:Map' xmlns:apachesoap='http://xml.apache.org/xml-soap'>         <item>           <key xsi:type='xsd:string'>property1</key>           <value xsi:type='xsd:string'></value>         </item>         <item>           <key xsi:type='xsd:string'>property2</key>           <value xsi:type='xsd:string'></value>         </item>         <item>           <key xsi:type='xsd:string'>property3</key>           <value xsi:type='xsd:string'>z</value>         </item>       </args>     </intf:webservice_controller>   </SOAP-ENV:Body> </SOAP-ENV:Envelope>

  1. This behavior is documented in Flex 3.0 manuals. See Dynamic Classes for more information. A direct quote:

    […]Methods created in this way, however, do not have access to any private properties or methods of the [example] class. Moreover, even references to public properties or methods of the [example] class must be qualified with either the this keyword or the class name.
