Hi Johan, The unmarshalling error basically means that the code thought it had processed everything in the <owner> element content, but hadn't found anything to do with the <collectiontypeone> element. That's very strange, especially since you show the contained <structure> is required (meaning JiBX should find something to match it or will complain about it being missing).
So I'm not sure why you're getting the unmarshalling error, but your binding is unnecessarily complex and that might indirectly cause some problems. As you've outlined it, there's no need to even have the <mapping> elements for java.util.ArrayList and GenericCustomCollection present in the binding. You can just remove these, and also remove the extends="GenericCustomCollection" attribute from the two specific collection <mapping>s. JiBX will then use the runtime type of the collection instance to choose between <collectiontypeone> and <collectiontypetwo> when marshalling, and will use the element name to decide which to create when unmarshalling. - Dennis Dennis M.
