Defining trigger actions over remote tables

[Kodachi]

As of today I am facing a terrible problem with defining trigger updates and deletes on remote tables.

Consider a view X created as:

create view X as
select «columns» from
X@«dblink»

I then define a trigger over that view in the following way:

create or replace trigger X_t
instead of insert or update or delete on X
for each row
begin
if inserting then «insert on X@«dblink»»
end if;

if updating then «update on X@«dblink»»
end if;

if deleting then «delete on X@«dblink»»
end if;
end;
/

When I insert tuples on view X, the insertion is propagated successfully.

However, when I update or delete over view X, I get the infamous:

ORA-03113: end-of-file on communication channel

I am practically despairing as I have searched and searched for ways to workaround this problem and I just can't understand what's wrong with my code.
