Reference to rows not working as expected

[Rudja]

Hello everyone,

I am trying to build an application where it should be possible to edit an object at two different places into a form. I'm using tabs for this form. 

Let's simplify my issue. 

My form
Tab1 - Tab2 - Tab3 - Tab4
Each tab represents a step for a project. 

In Tab3, I have an inline object. When you click on it, you are redirected to a form, where you can edit all the fields. This step is OK for me. 

Into Tab3, I need to put the same inline object again and be able to edit it. So I have created a virtual column, indicating the REF_ROWS("T_Chantier", "ProjetId"). It is working since I can see the inline object, but when I click on it, I'm redirected to a specific detail page and I can do nothing on it. Only a "Done" button is visible at the bottom. See the image below.

So what can I do to be able to edit the fields of this last view, please? 
If you need more information, do not hesitate. 

I joined the pictures below.

Inline object ok and I can interact with it (add a new one and edit it after clicking )Same inline object. I cannot add a new one and when I click on it, I am redirected on a "specific" detail view. I cannot edit anything on it.Detail view with "done" action only
