instance field array crashes

[phr34k]

The visualizer crashes when you use it to expose an array based property in instance fields. It seems to work fine for user-defined structs, I believe it's related not being able to figure out the associated part filestream to display.

Could you provide a simple example that reproduces this problem?

I think I've found one:

meta:
  id: value_inst_array
instances:
  v:
    value: '[1000, 2000, 3000]'

After expanding v in the object tree:
