Hi Günther, The problem with this binding is that in order to have the <collection> as a child of the <mapping> with flexible='true' you need to define a name for the collection - a wrapper element around the items in the collection. This is needed so that JiBX can generate code that "knows" the possible element names to be handled and can ignore the rest, as appropriate for flexible='true'.
If you're using an XML representation that you can't control, and that representation doesn't have any wrapper element, I realize you can't add a name on the collection. In this case the best you can do is probably to use a custom marshaller/unmarshaller for the Customer class. You can still define a <mapping> for the Address class, and your custom code for Customer can invoke this as needed. See the tutorial on this for more details: http://jibx.sourceforge.net/tutorial/binding-custom.html#marunmar - Dennis Dennis M.
