Comment #4 on issue 491 by andrehoraa: VerveineJ: MSE is not exporting implemented interfaces http://code.google.com/p/moose-technology/issues/detail?id=491
The problem was that if a class implemented interfaces, VerveiveJ was not exporting this information. Now it is exporting and, as consequence, now it is possible to use next/previous for Inheritance (like a "multiple inheritance", similar what InFusion do).
