ComponentArray errors with `findall`

[pdeffebach]

Is this expected behavior?

It's causing some annoying bugs for me.

julia> t = ComponentArray(a = [1, 2], b = [3, 4])
ComponentVector{Int64}(a = [1, 2], b = [3, 4])

julia> findall(<(2), t)
ERROR: MethodError: Cannot `convert` an object of type Int64 to an object of type Symbol
