Ember sanity check

gistfile1.coffee

# in my otherwise-working app:

GG.tasksController = Ember.ArrayController.create
  content    : []
  currentTask: null

GG.Drake = Ember.Object.extend
  
  # (...)
  
  visibleGenotype: (->
    visibleGenes = GG.tasksController.getPath 'currentTask.visibleGenes'
    debugger
    GG.genetics.filterGenotype @get('genotype'), visibleGenes
  ).property('GG.tasksController.currentTask', 'genotype').cacheable()

# debugger statement is reached when app starts up. However...

# later, in Web Inspector console:

GG.tasksController.set('currentTask', GG.Task.create({visibleGenes: ['Fl']}))

# debugger statement is not reached.
