Thank you for your help.
Now I have another problem :
buildEditorFor: anItem
^(anItem description copy
addCondition: [:memento | (Item repository
contains: [:each | memento model id = each not]) not]
labelled: 'An item with that id already exists';
asComponentOn: anItem)
addValidatedForm;
yourself
The memento model id doesn't change it's value when I edit it. I saw
MACheckedMemento has a #cache and a #original method, maybe I should use them, but I
don't know how.

Likely that you're using the same component
for the entire length
of the
session. You may want to copy the description as well, I don't
recall if
Magritte still caches its descriptions, so say anItem description copy
addCondtion.
Yes, you have to copy the description, else your globally cached
description ends up with a whole set of conditions.
Caching can be disabled by using a different description-builder,
however need the descriptions a lot (e.g. searching, persistency) it
is really worth to let Magritte only build them once and then cache
them.
