SLICE-Issue-2903-EntryFieldHasErrorAndGrayedLabel-FernandoOlivero.1 The idea is to have specialized Editors that know the validity of the contents being edited. For example i'm working on a CompletionEditor, which knows if the contents are a valid class of the system. For now i've added the method Editor>>hasError ^ false. I will push the CompletionEditor, and the CompletionEntryFieldMorph in a new issue. I've also added the grayed out background label , setted by sending #initialContents. Fernando
