Editor Customfield: without editor

[Maurizio67]

Hello,
I see several topics on this issue but I'm still facing the same problem (so I guess it's not yet resolved).
I need to use a Customfield with a rich structure, so I think the Editor type should fit... but the editor is not appearing.
The version used is: VirtueMart 4.0.7 10701 (with J4.2.2)

Any suggestion about this?

Thanks in advance
Maurizio
