Sorry I forgot a part of my request, what i would like is to add in my relation browser my custom relations. The OOTB ones are correctly displayed
I tried to modify the stylesheet "RB_UIConfigure.xml" but that did not solve my problem.
Do you have an idea ?
The problem was that to correctly displayed the relation added in the "RB_UIConfigure.xml", a total reboot of the internet browser is needed.
