You need to make a concrete class for ChangeableIntervalParameter that implements the IXMLSchemaInstance interface. That will allow you to hint to the SOAPEncoder the exact xsi:type you want. Then make a ChangeableSelectionParameter class that extends the ChangeableIntervalParameter and has get/set for each of the properties of the actual type you are trying to create. When you make up the parameters to pass into the web service, instantiate the ChangeableSelectionParameter class (along with a QName) and populate with the arguments and pass that into the web service. Since you have implemented the IXMLSchemaInstance, the SOAPEncoder will be able to correctly work out the type of the arguments and it will work. You need Flex 2.0.1 Hotfix 1 to do this, you can use the docs for Flex 3 to reference - http://livedocs.adobe.com/labs/flex3/langref/mx/rpc/xml/IXMLSchemaInstance.html Hehe, someone else helped me out with this just last week!
