Putting a bean into flow/flash/conversation scope that is created with a ProxyFactoryBean results in the exception:

org.springframework.webflow.execution.repository.continuation.ContinuationCreationException: Could not serialize flow execution; make sure all objects stored in flow or flash scope are serializable; nested exception is java.io.NotSerializableException: org.springframework.aop.framework.adapter.DefaultAdvisorAdapterRegistry Caused by: java.io.NotSerializableException: org.springframework.aop.framework.adapter.DefaultAdvisorAdapterRegistry at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1375) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1347) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1290) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1079) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:302) at java.util.HashMap.writeObject(HashMap.java:985) at

A ProxyFactoryBean is generally not intended to be serializable; only a proxy that it builds is serializable. Hence I'll turn this into an enhancement request for making ProxyFactoryBean instances themselves serializable as well.

This is unfortunately a non-trivial problem that we can only properly address in Spring 2.1 M4 but not backport to Spring 2.0.7.

ProxyFactoryBean and its superclasses and dependent objects are fully serializable now, as far as possible (i.e. as far as the target and interceptors are serializable as well).

This should be available in tomorrow's 2.1 M4 snapshot.
