Yes, indeed. Cheers Werner

After my long winded explaination I figured it out. I just have to call unmarshal.setClass(WalletFlexFacade.class) to make it unmarshal to that Class. Craig.

I'm currently running v1.3.1 and have the following mapping: <class name="com.some.domain.Wallet"> <map-to xml="Wallet" /> <!-- Bunch of properties --> </class> <!-- Wallet that has special properties used to facilitate marshalling which is not easily achieved using just the plain Domain objects --> <class name="com.some.domain.WalletFlexFacade" extends="com.some.domain.Wallet"> <map-to xml="Wallet" /> <field name="expenseRequests" collection="collection" type="com.some.domain.flex.ExpenseRequestFlexFacade"> <bind-xml name="ErLine" /> </field> </class> I then unmarshal some XML that has the<ErLine> elements in them like so: String _MAPPING = XMLMapper.class.getResource("/resources/mapping/DomainObjectsMapping.xml").toExternalForm(); Mapping _MAP = new Mapping(); _MAP.loadMapping(_MAPPING); InputSource xmlSource = new InputSource(new StringReader(xml)); Unmarshaller unmarshal = new Unmarshaller(_MAP); unmarshal.setValidation(false); Object object = unmarshal.unmarshal(xmlSource); In the log I get this: DEBUG - Get descriptor for: com.some.domain.ErLine found: null DEBUG - Now in method: org.exolab.castor.xml.util.resolvers.ByIntrospection resolving: com.some.domain.ErLine DEBUG - Ignored problem at loading class: com.some.domain.ErLine through class loader: sun.misc.launcher$appclassloa...@601bb1, exception: java.lang.ClassNotFoundException: com.some.domain.ErLine DEBUG - Called addAllDescriptors with null or empty descriptor map DEBUG - Get descriptor for: com.some.domain.ErLine found: null DEBUG - Adding class name to missing classes: com.some.domain.ErLine DEBUG - unable to find FieldDescriptor for 'ErLine' in ClassDescriptor of Wallet - ignoring extra element. DEBUG - unable to find FieldDescriptor for 'ErLine' in ClassDescriptor of Wallet - ignoring extra element. DEBUG - unable to find FieldDescriptor for 'ErLine' in ClassDescriptor of Wallet - ignoring extra element. Ok, I think to myself, for some reason Castor can't work backwards from the <bind-xml> statement for the ErLine element to realize that<ErLine> really maps to ExpenseRequestFlexFacade (and the get/setExpenseRequestFacade) when unmarshalling... Also, the "object" being returned from unmarshal.unmarshal(..) ends up being is a Wallet, not a WalletFlexFacade!!!! So what I do is add "setErLine/getErLine" methods to WalletFlexFacade and change the<field> name attribute in the mapping from "expenseRequests" to "erLines" in hopes that Castor will notice that WalletFlexFacade is the right class to instantiate, not Wallet. Nope, that didn't work. It's just hell bent on using "Wallet". So my question here is: How do I get it to use a WalletFlexFacade and not the parent class (Wallet) when unmarshaling?
