tf transformer

[YakirHuri]

hi,
if i have this tf three: map->odom->base_link, and if i run rostopic echo /tf and there is no msg like : map to base_link,
but in c++ code i can call lookupTransform with the frames "map" to "base_link" (because the odom frame connect between them),
and its work,

but when i run it with ros.net it return false: the method
getLatestCommonTime have the error string : NO CONNECTIONSZSZ: NO_PARENT DOES NOT CONNECT TO /map
