ok, if I refresh the edit part everything works correctly
But now I'm curious: what is causes of this behavior?
Why in your example the lists returned by getModelChildren() are
different from the lists returned by getChildren().getModel()
(debugging the code of your example i've noticed that this is the
difference)?
Sorry if I'm boring you with my question and thank you for your help

In the EDiagram example, the two lists (of attributes and operations) are
the model for the two CompartmentEditParts (equivalent to your
ListEditPart). The point to realize here is that the although the
attribute/operation has changed, the list containing it has not changed. If
you call refreshChildren() on the ClassEditPart, it will check to see if
EditParts exist for all the model children (which are the two lists). Since
they do, it won't make any change. Ideally, you'd want the notification of
the change in attributes/operation to go directly to the ListEditPart.
