I’ve run into several cases when I need to observe properties within an array of properties within an array of properties within an … you get the idea. But the @each observer is known (almost famously) to go only one level deep:
Note that @each only works one level deep. You cannot use nested forms like todos.@each.owner.name or todos.@each.owner.@each.name
Here’s one implementation of observed nested properties on stackoverflow but it appears pretty clunky looking.
Are there any plans to observe properties multiple levels deep?
