Can I pass complex objects as inputs to Spring WebFlow Subflows?

From:

http://docs.spring.io/spring-webflow/docs/current/reference/htmlsingle/#subflow-state-element-input

I see that I can specify a type for flow input (and output) elements, but I don't see any indication of whether those types can be anything other than simple, single-value types.

If I'm using a Flow as a Subflow, I have some cases where I'd like to pass a POJO or a Map. I'm guessing this is not supported, but want to confirm that before I proceed in trying to make those cases work.

(BTW, I realize I can pass objects by placing them directly on some accessible scope. I'm asking specifically about input/output)

You can use:

<input name="myObject" type="com.example.MyObject"/>

With MyObject being Serializable.

For a map you would have to use an implementation type that is Serializable as well 

<input name="myObject" type="java.util.HashMap"/>

You can map anything you want to your output as well
