[sr-dev] t_set_fr() error

i stored timeouts to local cfg variables and tried to set them with t_set_fr: xlog("about to set fr to $sel(cfg_get.local.invite_timeout)/$sel(cfg_get.local.gw_timeout)\n"); t_set_fr("$sel(cfg_get.local.invite_timeout)", "$sel(cfg_get.local.gw_timeout)"); xlog("after setting fr\n"); unfortunately, the above t_set_fr results in syslog error: Mar 30 21:05:10 localhost /usr/sbin/sip-proxy[31365]: ERROR: about to set fr to 75000/3000 Mar 30 21:05:10 localhost /usr/sbin/sip-proxy[31365]: ERROR: <core> [sr_module.c:1546]: Could not convert PV to int Mar 30 21:05:10 localhost /usr/sbin/sip-proxy[31365]: ERROR: after setting fr why is that? the two local cfg variables have been set to int values and no conversion should be needed: Mar 30 21:05:00 localhost /usr/sbin/sip-proxy[31367]: INFO: Handling XMLRPC POST from <127.0.0.1> with body <<?xml version="1.0" ?><methodCall><methodName>cfg.set_now_int</methodName><params><param><value><string>local</string></value></param><param><value><string>invite_timeout</string></value></param><param><value><int>75000</int></value></param></params></methodCall>> Mar 30 21:05:00 localhost /usr/sbin/sip-proxy[31367]: INFO: <core> [cfg/cfg_ctx.c:411]: INFO: cfg_set_now(): local.invite_timeout has been changed to 75000 Mar 30 21:05:03 localhost /usr/sbin/sip-proxy[31363]: INFO: Handling XMLRPC POST from <127.0.0.1> with body <<?xml version="1.0" ?><methodCall><methodName>cfg.set_now_int</methodName><params><param><value><string>local</string></value></param><param><value><string>gw_timeout</string></value></param><param><value><int>3000</int></value></param></params></methodCall>> Mar 30 21:05:03 localhost /usr/sbin/sip-proxy[31363]: INFO: <core> [cfg/cfg_ctx.c:411]: INFO: cfg_set_now(): local.gw_timeout has been changed to 3000 this is with current master branch. -- juha ps. it took a while before i found where the error comes from because there is no script line number in the message.
