Hello, I have "Model" class, dictionary instance variable in it and in this dictionary, there is "Task" and "Meeting" classes (Meeting is subclass of Task). I have problem with fuelAfterMaterialization order, if I log debug line in fuelAfterMaterialization, I got this fuelAfterMaterialization call order: Task Task Task ... Task Model (!) - here? why? Model is root object Meeting Meeting Meeting and some other objects, collections etc. Problem is, when I need to do some things with Tasks and Meetings in fuelAfterMaterialization of Model (eg. rebuild caches), I am excepting, that all fuelAfterMaterialization calls is done before on all Tasks and Meetings - because they are stored in instance var dictionary of Model. Is it a bug? Thanks! Petr Fischer
