Re: MADateDescription and nil objects

Hi Lukas Hum, I shouldn't trust my own memory. In fact, the problem has nothing to do with the date format but when Magritte is committing the changes to the original object. I can reproduce the problem with a form structure (Pier.72, Magritte. 142). 1) Create a form 2) Edit the meta of that form 3) Add a date element 4) Save the element 5) Save the meta 6) Edit the form 7) Assign a date 8) Save the form 9) Edit the form 10) Select the date and delete it (the field should be empty) 11) Save the form At that moment, I get this traceback: MessageNotUnderstood: UndefinedObject>>start UndefinedObject(Object)>>doesNotUnderstand: #start self nil temps aMessage start Date(Timespan)>>= self 2 March 2006 temps comparand nil inst vars start 2006-03-02T00:00:00+00:00 duration 1:00:00:00 [] in Dictionary>>= {[:assoc | (aDictionary at: assoc key ifAbsent: [^ false]) = assoc v...]} self a Dictionary(a MADateDescription label: 'Date' comment: nil- temps aDictionary a Dictionary(a MADateDescription label: 'Date' comment: nil->2 March 2006 a MAStringDescription labe...etc... assoc a MADateDescription label: 'Date' comment: nil->nil inst vars tally 2 array #(nil nil a MAStringDescription label: 'Title' comment: nil- Dictionary(Set)>>do: self a Dictionary(a MADateDescription label: 'Date' comment: nil- temps aBlock [] in Dictionary>>= {[:assoc | (aDictionary at: assoc key ifAbsent: [^ false]) = assoc v......etc... index 5 each a MADateDescription label: 'Date' comment: nil->nil indexLimiT 6 inst vars tally 2 array #(nil nil a MAStringDescription label: 'Title' comment: nil- Dictionary>>associationsDo: self a Dictionary(a MADateDescription label: 'Date' comment: nil- temps aBlock [] in Dictionary>>= {[:assoc | (aDictionary at: assoc key ifAbsent: [^ false]) = assoc v......etc... inst vars tally 2 array #(nil nil a MAStringDescription label: 'Title' comment: nil-
