[SR-Users] $avp reset to <null> with no reason?

[Uri Shacked]

Hi,****

** **

I encountered a problem. While doing some avp's settings I notice that one
avp that I use is changing to <null> without me doing anything.****

** **

Here is the part of the cfg file:****

………….****

………….****

Route[SET]{****

…………..****

$avp(Sfeaturetype)=$avp(next_feature_type);****

…………****

Route(DIDSRV);****

}****

** **

route[DIDSRV] {****

xlog("L_CRIT","$C(rg) SCRIPT: in DIDSRV type = $avp(Sfeaturetype), index =
$avp(SfeatureIndx) $C(xx)\n");****

if($var(srvcount)>3){****

xlog("L_NOTICE","$C(rg)Too many services loops $C(xx)\n");****

update_stat("nts_subs_srv_loop", "+1");****

$avp(TRMCS)="10";****

t_reply(403,"too many loops");****

exit;****

}****

$var(srvcount)=($var(srvcount)+1);****

xlog("L_CRIT","$C(rg) SCRIPT: in DIDSRV before switch to $avp(SfeatureType)
or $avp(next_feature_type) $C(xx)\n");****

switch ($avp(SfeatureType)){****

case "0" :****

……….****

………****

** **

On the route "SET" I put the value from the $avp(next_feature_type) in
$avp(Sfeaturetype).****

After that I call the route "DIDSRV" and use switch($avp(Sfeaturetype)).
Before the switch I xlog the value of the avp twice.****

As you can see in the log below, on the first xlog print, the value is 0
(as I expect). On the second print it resets to <null>****

WHY?****
