Hi, What could be the reason a ViewModel cannot be recreated with the exception below ? Looking at org.apache.isis.objectstore.jdo.datanucleus.persistence.spi.JdoObjectIdSerializer#toJdoObjectId() it tries to find '_' separator and use the string before it to decide what class to load (byte, int, UUID, ...).
In my case the ViewModel extends from an abstract ViewModel. The parent one is annotated with @ViewModel and the child one with @DomainObject(nature = Nature.VIEW_MODEL). I've tried different combinations with the annotations but it always leads to this exception.
