I think I found the cause. NormalisedEntityPersister.postInstantiate() seems to lack knowledge of composite objects within ID types (doesn't use getColumnSpan()). 

By adding / replacing the following code (from EntityPersister) I got it to work: 

... 
Type[] subtypes = actype.getSubtypes(); 
... 
int j = 0; 
for (int i = 0; i < props.length; i++) 
{ 
String subidpath = idpath + StringHelper.DOT + props[i]; 
String[] componentColumns = new String[subtypes[i].getColumnSpan(factory)]; 
for (int k = 0; k < componentColumns.length; k++) 
{ 
componentColumns[k] = columns[j++]; 
} 
columnNamesByPropertyPath.put(subidpath, componentColumns); 
mods.put(subidpath, actype.getSubtypes()[i]); 
}
