Hi everybody,

I would like to show a header_text field in my fieldset, if an asset is chosen (is not null).

Well, this is what I did:

      background:
        container: main
        folder: /
        restrict: false
        type: assets
        display: Background
      header_text:
        restrict_assets: false
        type: redactor
        display: Text
        show_when:
          background: not null

But unfortunately background: not null is always true.

Any idea here?
