Problems with LINK.DENY and LINK.APPROVE events

There is an inconsistency in Link object/tag used in LINK.DENY and
LINK.APPROVE events.

Fix should be applied to all CATALOG items.

If we do APPROVE/DENY via Catalog <inp2:l_Field name="..."/> tag would
work just fine.

But if we do APPROVE/DENY via Advanced VIew <inp2:l_Field name="..."/>
tag won't work, instead we should use <inp2:l.showall_Field name="..."/
> tag (with special).

Situation is not obvious for users and seems to be inconsistent to me.
Any ideas how this can be fixed besides using IFs to check if first
object is loaded and if not use the second one?
