Trying to make Issues readable for other users of the same customer (linked via Contact). Portal’s list view shows them, but you can not read or edit if you didn’t create them.
In theory, un-checking Role Permission Manager’s “Only If Creator” could do just that but doesn’t, at least not here (15.98.1).
So I tried some hooks (has_permission, override_doctype_class, override_whitelisted_methods) but none worked, tried to override issues/[issue name] but code never executed or was never in the the ri path.
So besides telling the customer “Only one of you can file issues”, what does one do?
