Unfortunately I get again the following errors.

I attached the tarball of the test project.
I you have time to have a look and eventually to tell me if I am doing some wrong.

Thank you very much

Summary: I believe this bug is fixed with the latest changes I pushed in 
Rock. Please tell me if I am wrong.


Long explanation
-----------------
The problem came from a type export policy change I recently did on oroGen.

Registering a type in the RTT type system is pretty costly in terms of 
compilation time. Since people that use Rock-only (i.e. the Ruby tools) 
don't need to register all types, I changed the default in oroGen to 
export only types that are used in task interfaces. typegen-generated 
typekits would export all types (obviously).

However, for the XML marshalling to work, all types *also* need to be 
registered in RTT.

So:
* the default is back to export all types in oroGen. Rock autoproj
   configuration changes that to export only used types for rock users
* a new configuration option in Rock's autoproj configuration allows
   to require OCL compatibility, in which case all types are exported.

So, if you answer 'yes' to OCL compatibility, it should work as expected.
