Error generating marshallers: Cannot convert from List to ArrayList<Something>

[navigateur]

For every "ArrayList" variable I'm using in a @Portable class, I'm getting:

{code}
37. ERROR in C:\Users\admin\AppData\Local\Temp\errai\7c2aa826f82ceab411fec8e8a739446fbc592f2afe682331fe9ed5ee771\errai.marshalling\gen\org\jboss\errai\marshalling\server\impl\ServerMarshallingFactoryImpl.java (at line 438)
          entity.relatedStatements = java_util_ArrayList.demarshall(obj.get("relatedStatements"), a1);
                                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Type mismatch: cannot convert from List to ArrayList<Id>
{code}

How do I make it work?

Removing the "public" modifier made it work for now, but I'd like to be able to use public fields.

Yes, that looks like a bug. Errai marshalling should work with public fields. Can you open an issue for this at issue.jboss.org?
