somehow proxy is getting an instance of a class which isn't build for : at org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler.invoke( LazyInitProxyFactory.java:402) at org.apache.wicket.proxy.$Proxy76.searchDocuments(Unknown Source) at x.document.page.document.search.AdvancedSearchDocument.search( AdvancedSearchDocument.java:156) So it sounds to me that the wicket proxy resolves a wrong object when it deserializes.. Or maybe it suddenly resolves to a diffect class of that object, but i don't know how likely that is..
