App engine does not store List when it is annotated with serializable and defaultFetchGroup set

I am trying to store an Jdo which has a List in it. When the list is annotated with 

@Persistent (defaultFetchGroup = "true")

It works fine, but when I have 

@Persistent (serializable = "true", defaultFetchGroup = "true")

It does not store the list. Does anyone know why? What do I do when I have a list of custom objects that I want to store, do I mark them as serializable or not?
