RubyAMF and Rails 2.3.3

Nevermind ... I found several name expansion problems in my code. After fixing Ruby AMF 1.6.5 worked fine with Rails 2.3.3.

After further research, I ran into the problem again. Seems like RubyAMF is choking on serialization. Any hints on how / what to dig deeper into this issue?

You have a nil object when you didn't expect it!

You might have expected an instance of Array.

The error occurred while evaluating nil.include?
