Thank you for your quick reply. What I find odd is that this error seems to be
coming from within:
GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure:
self shouldCallPreviousPersistence ifTrue: [
previousPersistence ensure: existingDictionary ].
So there is the "Fuel" Persistence and we want to migrate things. Fair enough
but in the migration we do have:
>>load: existingDictionary
"It loads stored information into existingDictionary."
self preferences exists ifFalse: [
"This is a new computer, so we define new computer UUID.
User still has to agree about sending data if it is not has
been done yet."
^ self save: existingDictionary ].
So self preferences exists is true and now the old (non-existent data?) is
being saved and we crash and exit on save.
* Why isn't the migration from Ston to Fuel more explicit?
* Why is "load" trying to save?
* Why is "ensure:" used instead of load?
* Not sure why "self preferences exists" seems to end in true?
have a nice weekend
