problem with relation reverse in v3.0 BETA

Hello

I have created a relation field for a type 'A' which point to a field of type 'B'.

I want to create in type 'B' a Reverse relation field which points to the previous type 'A' field (relation field).

I don't find in the reverse relation parameters how to enter the reverse link.

I only get this parameter :
[attachment=0:3o0lelay]<!-- ia0 -->reverse_field_parameter.png<!-- ia0 -->[/attachment:3o0lelay]

How can I create this reverse link ?

thank you for explanations

Best regards

Michel

Hello

in

relation_reverse.xml

replace:
<fieldset name="group-relation_reverse"

for:
<fieldset name="group-relation_reverse-v"

thank you

It's working now.

Just a detail : in the backend when I click on the reverse relation field, the page linked is not displayed,I get this :
[attachment=0:3cd02j59]<!-- ia0 -->Panneau d administration.png<!-- ia0 -->[/attachment:3cd02j59]

It seems to be the content of the home page.
I think the problem is a SEO one :

The article page in the admin is :
/index.php?option=com_flexicontent&task=items.edit&cid[]=2

the hyperlink of the reverse relation is :
/index.php/site_content/2-uncategorised/16-efraim

Presently it's not a problem for me. I jusst wanted to signal the problem

best regards
