[OpenSIPS-Users] How to get is_from_gw to fill gw_id_avp

[mayamatakeshi]

Hello, can anyone give me an example of how to call drouting function
is_from_gw ?

http://www.opensips.org/html/docs/modules/1.9.x/drouting.html#id293958
<http://www.opensips.org/html/docs/modules/devel/drouting.html#id294786>

The doc gives this example:
    if (is_from_gw("3","1")
which seems to be incorrect as "1" is not a valid flag.

I am trying to use flag "i" to get the gwid in the AVP set using gw_id_avp
but it is not working.
I already tried as:
    if (is_from_gw("", "i"))
and
    if (is_from_gw("0", "i"))
but it is not working: the avp set by avp_gw_id is no filled.
I know my configuration is correct because do_routing() does fill the avp.

Obs: the doc also says that if I don't care about the type of the gateway I
can pass a negative number.
So I tried:
    if (is_from_gw("-1", "i")
But then i get:
Aug  3 16:53:44 SERVER /usr/local/src/git/opensips-head/opensips[1454]:

In case this is a bug, I tried with this git commit (head):
