I thought about that before, couldn't we create a custom
VariableResolver/ELResolver using decorator pattern to load beans fro mflow
scope when parent call fails? We could declare the bean in
trinidad-config.xml using the same syntax as faces-config.xml.

The simplest possible solution I can come up with is:
- Continue to require pageFlowScope as an EL prefix:
#{pageFlowScope.foo}
- Enhance the pageFlowScope resolution so that, if a lookup
fails, it will:
- Perform a general VariableResolver lookup for that
as a top-level variable
- If we get back a non-null value, see if the class
has an annotation (like you say)
- If so, push it into pageFlowScope
It wouldn't help you for #{foo}, but it would help you
for #{pageFlowScope.foo}.
