Cross-referencing nested inputs

[xian]

I'm trying to reference nested inputs between multiple levels, without any success so far. This document describes how to reference nested inputs in the resources section: User input in VMware Aria Automation requests

What I want to do is to reference these inputs in the inputs section, to provide dynamic default values or dynamic list of values, depending on other input fields.

Referencing on the same level works, here is a simple example:

inputs:
  size1:
    type: number
  doublesize1:
    type: number
    $dynamicDefault: /data/vro-actions/com.test/double?num={{size1}}
  level2:
    type: object
    properties:
      size2:
        type: number
      doublesize2:
        type: number
        $dynamicDefault: /data/vro-actions/com.test/double?num={{size2}}

This will result in the following form:

However, I cannot reference size1 input in level2 doublesize2, and vice versa, I cannot reference size2 in doublesize1.

This limitation(?) applies to both cloud templates and custom forms.

Any suggestion how to workaround this, or this is a hard limitation?
