Yep, for end users the descriptions usually have to be filtered to the most basic properties. This is a copy of the code I used in some commercial application a few years ago (I just say that because today there are many more attributes nowadays, so you probably need to add some more selectors to #rejectedDescriptionFields). What the following code does is to remove some descriptions from the description to be edited. Moreover it makes the label to be required. buildEditor: aDescription title: aString | desc | desc := aDescription description reject: [ :each | self rejectedDescriptionFields includes: each accessor selector ]. desc := desc collect: [ :each | (each accessor selector = #label) ifTrue: [ each copy beRequired ] ifFalse: [ each ] ]. ^ (desc asComponentOn: aDescription) addValidatedForm; yourself. rejectedDescriptionFields ^ #( priority visible readonly persistent nilLabel ) Hope this helps, Lukas -- Lukas Renggli http://www.lukas-renggli.ch
