Hello,
I am now on version 7.7.6
On the calls / list view page :
if you change the date inline (= directly in the table), then the relationship "related to " is lost.
how to proceed :
from the page : /index.php?module=Calls&action=index&return_module=Calls&return_action=DetailView
change the date directly in the list, save, refresh the screen : relationship has disappeared !
This issue was tagged as “solved” in the 7.7.6 release, but in my case the issue remains.
Please tell me if you need more info.
