In this Twiddle I created a simple example of a component that has a computed property. The application controller simulates a model that has 2 instances and those instances are each passed to the component as a simple parameter. What I expected from this experiment was to have the first rendered component with the activity count as 1 and the other as 0.
living room - Activity 1 bedroom - Activity 0
but the actual result is
living room - Activity 1 bedroom - Activity 1
Am I missing something here? Thanks in advance.
