Answering myself. The doc says :
"you shouldn't need to expose the PK values as class' attributes. But,
ok, if you really want to do that, that is to say, if you declare them
as class properties, " 

That 's what i did, but this is wrong too, let read this 
snapshot:

===========================================================
from mortal.Objects.Article import Article
from Modeling.EditingContext import EditingContext
from Modeling.FetchSpecification import FetchSpecification

# creating a new object
ec = EditingContext()
article = Article()
article.setText('Oups')
article.setTitle('Again')
ec.insertObject(article)
ec.saveChanges()

# fetching the last inserted 
fetchSpec=FetchSpecification(entityName='Article')
ec.objectsWithFetchSpecification(fetchSpec)[-1]
<mortal.Objects.Article.Article instance at 0x85cfd44>
ec.objectsWithFetchSpecification(fetchSpec)[-1].getId()
# <---> the id is 0 cause the fetch isn't done here.
0 
ec.dispose()
# <--> after a dispose it's work . 
ec.objectsWithFetchSpecification(fetchSpec)[-1].getId()
26L
==========================================================

1) first i don't want to dispose each time i insert a new object
   cause this can really be time consumming

2) for an unknow reason right now, (perhaps i'll debug that) 
   even calling dispose() on my ec don't force a re-fecht
   in a real application


So do you have any idea on how shoud i try ?
