using

{IPADDRESS}

macro in map labels results in inaccessible map (both config & monitoring) and an error message :
[ZABBIX_ERROR] Undefined index: ip[/home/main/usr/local/apache2/htdocs/trunk/include/maps.inc.php:616]

would be useful to check all other possible locations where frontend might need a host ip and maybe even somehow abstract it so that it doesn't have to be implemented dozen of times individually...
